Buy this plant from me - Dwarf Red Canna

This morning I snapped a quick picture of this dwarf, red Canna. This is its first bloom of the season.
As you may know, Cannas love full sun and plenty of water. It's difficult to overwater them! Cannas can be placed into a pot in a new or existing pond, or planted out in the ditch that might exist in your yard.
I was thinking $5 or a trade/barter would be a good price, as this is a 100% organic offering of an edible plant beautiful enough for the front yard.
Thank you for checking out my plants. More offerings to come in the future. Ok to ask questions, even dumb ones.

Opuntia Placed Using the STUN method.

     I may have said before that I am a huge fan of Mark Sheppard's STUN method of gardening, which is short for Sheer Total Utter Neglect.  In short, you plant a whole lot of the thing you want to grow, as many different varieties as you wish, collect the seeds of the survivors, and continue to plant and collect seed of future generations so that you will be growing the best, most adapted plants for your space.
     So I pruned all of my Opuntia, which came out to a lot more than I had thought it would. Filling up an entire bucket! From my postage stamp yard I was impressed. These are not old and large plants, but tiny things I have found in the neighborhood and bought one at the botancal gardens. These are the native Opuntias, be cautious when handling!

     Then I took all the tunas to the new property, which I am going to have to give a name to. I had wanted to make a fortress of solitude out of the place complete with a moat of Cactus all around it, but as yet I dont have enough plant matter for that. So I placed them all in the ground in a protected area. Could always move them later on. I was delighted to find the sand was moist about an inch deep, perfect for these cacti! With any luck, I can STUN these into thousands more plants for my moat.

Opuntia, a revisiting

     I have been rethinking the case for planting spiny Opuntia at the new place. The spiny Prickly Pear still makes a delicious fruit, and it has the added benefit of keeping out people, deer, and anything else soft and fleshy.
There is a very nice overview here.
     I must have at least 20 starts in the front yard ready for transplant. Exciting!

Backyard Green Smoothie Recipe

1 loquat leaf
4 red hibiscus leaves
4 hibiscus leaves
6 lemon leaves
1/2 ginger leaf
rosemary - greens from one sprig 4" long
1-2 cups cold water

optional : canna - no added flavor, no significant nutrition
     lemongrass - tasty but adds a real "grassy" flavor
     mints

     Directions - add all ingredients to blender and blend on high for at least 30 seconds. There should be enough blending that a foam is created on the top, which quickly dissipates. Then pour through a strainer into a large enough jar to hold your smoothie, which should be enjoyed immediately or refrigerated and enjoyed within about 3 days. Take the strained contents to the compost heap, give to the rabbits now, or freeze into cubes for treats for the rabbits later.

Harvesting the Cranberry Hibiscus

     Earlier this spring my mother found these young plants at a garage sale, and they must have been priced well because she picked up one for me. It turned out the bargain annual happened to be the interesting and beautiful Hibiscus sabdariffa mentioned on the Florida Survival Gardening blog by David. No doubt the original seeds were from ECHO, as my mother lives not too far from there.

     I had no idea this plant could be so beautiful, unusual, useful, pest free, maintenance free...

     Today I am going to harvest the fruit. According to David, the round green bits are not the delicious part, but are where the seeds are stored. It's the red wrappers (or calyx) around the  round green fruit that is used for cooking and eating. This year recouping seeds is a high priority, since this is the only plant that I can source, and likely the only cranberry hibiscus growing in my county. It would be amazing to grow about 10 of these next year, as they like full sun. They do visibly wilt if you neglect to ensure hydration, but bounce back very easily and quickly. (I must have wilted it at least 5 times during the hot part of the summer.) Never would a tomato be this resilient.


       The leaves are edible, and I can tell you that the rabbits eat these leaves even before they eat their normal favorite weeds, Spanish Needle (Bidens alba). Although Hibiscus sabdariffa is tasty, none of the plants in the mallow family, or rose family, are particularly high in nitrogen (protein about 2 1/2%) - a consideration for overall rabbit dietary needs. I did eat a few of the leaves, which were very mild but did have a pretty tasty flavor, much better than Bidens, which is tart. These leaves would be good in a salad or on a sandwich (which is probably what I will be doing since the cold weather is here.)

     The seeds are higher in protein and very high in omega 6 fatty acids, and in quantity are valued as animal feed, particularly for chickens.

     This is the first and largest of probably two harvests from my one plant.

Turk's Cap Hibiscus, Malvaviscus penduliflorus, Sleepy Mallow, Mazapan

Uses: Edible, Xeriscaping, Forage, Medicinal. Native to: Mexico.
     This is another great plant that looks beautiful and blooms for most of the year. It's a great candidate for turf replacement, since it is very well-behaved once established. The bright red flowers attract pollinators including butterflies and hummingbirds.
     Perhaps one of the best things about Turk's Cap Hibiscus is that the leaves and flowers are edible, like all members of the mallow family. Wikipedia says, "Certain species of hibiscus are also beginning to be used more widely as a natural source of food coloring (E163), and replacement of Red #3 / E127." I have used it to color handmade soap, by making a tea for the water portion of my recipe, coloring the soap a pinkish hue.
     Have you ever had Celestial Seasonings Red Zinger tisane? According to their website, Hibiscus flower is their main ingredient. And after reading that list, doesn't it sounds pretty simple to make a version at home?

     Hibiscus flowers are known to be medicinal. They contain vitamin C and other vitamins and minerals. A study in 2008 found that it can lower blood pressure in mild cases. The flowers contain anthocyanins, acting as natural ACE inhibitors. This study reveals hibiscus' strong link to lessening the effects of metabolic syndrome. With a bit of looking, much more research can be found regarding the downward blood cholesterol effects of hibiscus. Some people are convinced the properties mentioned above can help them to lose weight.

Banana path update, one year later

     Remember the photo of these banana sticks that I planted last February?
     Surprisingly, all but one survived, and have turned into these beautiful, tropical trees. Photo taken in December.
     Underneath, on the southern side, I have decided to place another small sunken rabbit manure garden, planted up with taro, onions, annuals for the rabbits, and whatever else I can find.

Another Great Reason to Grow Lemon Trees

     There are several reasons to grow citrus trees even if your production of fruit turns out disappointing, or if you live in an apartment and only have room for a small plant in dim light indoors.
     Vitamins found in the leaves can be higher than the vitamins found in the fruit. This includes vitamin C, potassium, and vitamin A precursor. Potassium and vitamin C are not stored well by the body, so have to be replenished periodically by the diet. There is some evidence that dehydrating the leaves concentrates the vitamins, as long as the dehydrating is performed without excessive heat. Can we say valuable post-apocalyptic trading commodity? Also a great reason to enjoy herbal tisanes and justify the cost of an inexpensive solar dehydrator for the backyard.
     Citrus greening could become a problem, but not if you are growing the plants specifically for the leaves. Greening is the newest, baddest threat to Florida's citrus industry, basically an uncontrollable bacteria that causes fruit to improperly ripen. However, leaves are unaffected, and the bacteria is not a human pathogen. The best time to harvest leaves is right before the lemon trees flower and fruit, as that is when they will have the maximum nutrition. Meyer lemons flower in December, usually, and fruit a few months later. The flowers are fragrant and nutritious too! Citrus trees are perennials, so care must be taken to sustainably harvest them.
     As much as IFAS and the news sensationalize the plights of the citrus industry, most citrus trees are largely resistant to pests. Perhaps it is because those statistics come from the monocultured orchard citrus industry. Perhaps it's because most are already grafted before you have the opportunity to purchase the trees. Perhaps it is because most people's backyard citrus are not planted so densely so as to encourage the growth of pests and the lack of beneficial insects and bacteria. Remember this previous article about how the state destroyed thousands of homeowner's citrus trees, then lost a lawsuit because it was scientifically unfounded? It just shows that they don't really know the answers either.
     The fruit has many culinary uses. It is used in canning to lower pH and prevent oxidation. It can be used to cook raw fish without heat, but dehydrates the proteins - changing the texture. Lemonade. Household cleaner. Fragrance. Color. Limitless possibilities.
     It may have some medicinal properties. Although not thoroughly researched here in the US, lemon is used in Ayurveda in India. According to this study, lemon is used to treat disorders of the throat and persistent catarrh (inflammation of the mucous membranes usually in the airway, causing an overproduction of phlegm and mucus). The low pH of lemon juice inhibits bacterial growth. Certainly vitamin C is absolutely necessary in our diet. Remember this post where I wrote about vitamin C and guinea pigs (as a survival protein source)? We all need good nutrition.
     The recommendations for lemon culture from IFAS state that lemons are more vigorous than most citrus species and that dense plantings encourage pests. They are recommended for the warmest, sunniest part of the landscape that does not flood. IFAS doesn't recommend propagation by seed, but rather grafting onto a rootstock specifically chosen to avoid certain soil pathogens.

Cowpeas, Black-Eye Peas, Vigna unguiculata

Uses: Edible, Forage, Legumes, Xeriscaping. Native to: West Africa
     A true survival food, the cowpea is grown for its edible beans and leaves. It's a nitrogen-fixing legume, which allows it to grow in extremely poor soils. In addition, it's one of the best fodder plants for the deep south.
     Not only do cowpeas grow very well in this area, it seems that wildlife has very little interest in them. This can be a boon when squirrels and birds frequently do their best to defeat even the most resilient of gardeners.
     Plant cowpeas in the early spring, around the beginning of March if no additional freezes are reported. Plant them again at the end of September. They are a short-season annual that only needs about 3-4 months to produce a whole crop of beans. The beans germinate faster if soaked in clean water for 2-4 hours before planting. If desired, innoculate with additional nitrogen-fixing bacteria, but this step is not necessary in order to get good results. Grows very well in the full sun provided they plants have enough moisture to prevent wilting.
     Cowpeas have also been shown to be an excellent green manure and annual cover crop, as they grow in poor soil and have a short growing season. Supposedly they arrived in the US via the slave trade, and are still a New Years Day traditional holiday food in the south.
     Mine are originally from the grocery store, and I have been growing them now successfully for a while. I'm attempting to hybridize some cowpeas that particularly enjoy our weather and soil, though I have been amending the soil with rabbit manure for some time as well. This variety is low-growing and bushy, and can be planted very closely together to maximize your growing space. They are very well-behaved little plants, and will stay where they are placed. At the end of their cycle the beans and plants politely die and dry right on the plant, making harvest very easy.

Spiderwort, Tradescantia spp., Asparagus of the South

Uses : Edible, Forage, Xeriscaping. Native to : Eastern North America.
     There are several Tradescantia members that look similar, notably T. virginiana and T. ohiensis. The good news is that they are both edible. The bad news is that when anyone thinks of Tradescantia, they usually think of the striped (Wandering Jew) or purple (Purple Heart, Moses in a Boat), which are inedible.
     These purple beauties will bloom all spring, but each flower  is only open for a day or so. They are very successful, some might even say invasive, and can survive some mowing. The best practice is to relocate these hardy perennials to a flower bed in the full sun.
     Rabbits do enjoy eating them, along with some humans. Green Deane says:

     "Its leaves do not change in flavor as the plant ages. The leaves are good for salads as well, or in soup and stews but they are mucilaginous. The stems can be braised like asparagus. The flowers, at one time favorites for candying, make very pretty blue additions to back yard salads." 

   

Innovative Intensive Farming for the Humid Tropics

     I really enjoy this diagram for a self-sufficient farm in the semi-tropics. This particular plan calls for a large crop of sugar cane, which is processed into juice to feed the ducks and pigs. Perennial nitrogen-fixing forage trees are chopped to feed sheep, and azolla is cultivated to feed fish, sheep, ducks, and pigs.
     All the wastes are managed and recycled into the system to fertilize and prevent erosion. When done on a large enough scale, the meat and vegetable production could be great enough to take to market.
     This particular system could easily be modified for Florida by not changing a thing. Sugar cane grows well in most parts of the state, as does azolla and duckweed. The system might slow down in our cool winter, but should restart without any troubles in our warm spring. The daily chores would involve collecting food for the animals and managing livestock and manures. Like on any farm or homestead, the family's vegetable garden would need periodic tending. Overall, it looks like a balanced system with minimal outside inputs.
     The full description can be found here.
   

Survival Gardening in Florida, Part 2

     As far as growing carbohydrates, nothing really jumps out at me beyond sweet potatoes, cassava, sugarcane, the safe yams, and coontie, which are all very nutritious and pack a good deal of fiber as well. Also, kids like them. The leaves of all but coontie can be eaten or used as fodder. White potatoes are great too, if you are really good at growing them. Some grains that do well in Florida include amaranth and sorghum. Sorghum can be made into a tasty molasses if a person desired it. There are a ton of fruits that grow very well in Florida, the most well-loved being citrus, which can, with choosing proper varieties, be available for picking fresh about half the year. Canna, carrots, lilies, and cassava roots are all loaded with vitamins and nutrition. Sugarcane grows very well through most of the state. Bees love it here too.
     As far as growing fats, that's going to be a tough one. This might be a good time to mention micro-livestock like rabbits, guinea pigs, or chickens. Quail are great, but need an extremely high-protein feed as they naturally eat insects. Rabbits can live almost completely on grass and weeds. Chickens can live on almost completely grains and bugs. Fish can be raised in ponds or containers and fed things like azolla, duckweed, or garden worms.
     If I had to choose just three plants to grow to survive on, it would be cowpeas, cannas, and sweet potatoes. Cowpeas are a nitrogen-fixing legume that grow very well in poor soil and can be grown twice a year. The beans are high in protein and fiber, while the plant is high in protein for the rabbits. Cannas, aside from being beautiful and able to handle our hot, humid weather, can yield a starchy root and the leaves are high in vitamins for the rabbits. Sweet potatoes are a nutrient-dense starch, with very excellent tasting leaves which are high in protein. The leaves from all three plants can be eaten raw or cooked.
     Areas of the property which are not actively gardened can be, over time, landscaped with perennials that produce nutrition, fodder, or both. My favorite useful perennial is probably the wild rose bush. They don't have much of a smell, but make large, beautiful flowers that turn into rose hips - very nutritious. The leaves are good fodder and the thorns make the plant valuable for fencing. Thorned or thornless prickly pears are also a wonderful perennial, as the leaves are edible and the fruit is delicious. Plant those with an asiatic lily in between each bush and you will have created lush, flowery nutrition.

Actual Survival Gardening, Part 1

    Survival gardening is a phrase that has been thrown about and equated with permaculture, which it is not. Permaculture is lasting plantings of perennials which give abundantly year after year, while survival gardening is active gardening with a care to provide all of a person's nutritional needs.
     All nutritional needs. Fats, carbohydrates, proteins, fibers, trace minerals, and vitamins.
     There is a lot of debate as to how much land it would take to provide for all nutritional needs. Some people might say one acre per person, others more. Would all nutritional needs include meat and fish? what about the healthy fats that are in avocado and olives? So everyone is going to have their own opinion on land consumption, particularly in regards to climate and use, for example, like bio-intensive agriculture.
     I think as far as growing protein the first thing that jumps to mind is nut trees, and the first one that really jumps to mind is pecans. They grow really well in most parts of Florida, where other nuts fail. The rumors of a pecan blight exist, though I have not seen it for myself yet. Then there are bean plants, which are low-growing, sun-loving herbaceous protein factories. Peanuts, cowpeas, and green beans all do well here. Probably the best part about growing beans is that the plant stalk and leaves make great fodder for livestock once the beans are harvested. Sprouted grains are reputedly high in protein and vitamins.

Yucca gloriosa, Spanish Dagger

Uses : Fencing, Edible, Forage, Fiber, Wildlife. Native to : Southeastern US.
     There seems to be a lot of confusion over Spanish Bayonet and Spanish Dagger on the internet, and if you search for images of one or the other you will get both plants, some of which are improperly labeled. Here is what IFAS has to say on the subject:

"Spanish bayonet is often confused with Spanish Dagger. Leaf margins on Spanish Dagger (Yucca gloriosa) are smooth, whereas those on Yucca aloifolia (Spanish bayonet) are rough. The outer halves of the leaves on Spanish dagger also bend toward the ground, whereas those on Spanish bayonet do not."

     Finally, we have a clear ruling. I had thought my plants were Spanish Bayonet for the last few years in error, they were actually the less painful Spanish Dagger - although still quite painful! The leaves are rigid and spiky, and because the leaves point in every single direction it makes that plants as difficult to handle as a porcupine rolled in peanut oil. The spiky painfulness is probably why this plant is almost never commercially propagated, sad because it is a disease-free, sun-and-sand-loving, pest-resistant plant.
     It is a native in the yucca/agave family, and the flowers and fruit are edible. The white flowers attract bees. It is very easy to propagate, just dig any runners from the base of the plant and move to a sunny spot of the landscape. Very attractive and easy to care for in containers. The leaves are edible to rabbits. Can tolerate beach conditions. The roots contain saponins, but can be cooked to become edible. Or, perhaps, to yield soap? Like Century Plant, the leaves can be made into fibers for ropes, basketry, and clothing.
     It may get 15-20 feet high, then break off during a violent storm, as happened here. These leaves are going to become rabbit manure over the next few weeks.

Scrub Trees for Survival Fodder

     There has been a growing movement for farmers to seek additional feed sources for drought seasons and winter. Traditionally farmers would set aside dry feed or silage for the winter, but many have found themselves unprepared for warm seasons of extreme drought. This, like everything else, makes pastured meat more expensive.

     The Australians have really been looking into this problem, and they have suggested planting trees for fodder during drought. If done with alley-cropping techniques, this can actually increase pasture production thanks to the windbreaks and shade the trees will produce.

     If your animals are having trouble accepting the survival fodder, or you aren't sure what to feed them, more information is here. Rabbits can eat anything horses can eat, and I think goats and cattle as well. 

     Some of the best agricultural information is coming from the tropics these days.

Once fodder trees began to be planted on-farm, the 

technology spread rapidly throughout the region, as

farmers quickly realized the nutritional benefits of 

feeding fresh leaves to their cows.

Bamboo

Native to: Asia.  Uses: Edible, Forage, Xeriscaping, Fencing, Fuel, Building Material, Clothing Textile.
     I love bamboo. It's got a very tropical, Asian feel to it, indeed, it is the definition plant for Japanese-style gardens. It grows very quickly thanks to it's unique rhizomial adaptations. It has a million and one uses. And rabbits love it.
     I think most people should understand before they plant bamboo that it is a giant grass. And think of how hard it is to get rid of grass in Florida once it is established! So extreme care should be taken before a planting of bamboo is placed anywhere. It should probably not be planted over sewer lines, electrical lines, water pipes, etc.
     My large bamboo is in a pot, while my dwarf bamboo hides underneath a palmetto bush. Hopefully that will be good enough to keep my yard safe.
     This pile of bamboo was laying by the curb at a neighbor's house. Silly people.

Covert Urban Homesteading, Part 2: Animals

   Without animals, your urban homestead is really just a super-nice garden. To really maximize your land use, you will want to get some small herbivores to convert your kitchen waste and yard refuse into instant fertilizer and protein. It should be noted that since you have a homestead here, and not an urban farm, you should be trying to provide as much of your animal feed as possible yourself. Buying feed is not what homesteaders do, it's what urbanites do, right?
     Every one of these animals will need their human caregivers to protect them from human and animal threats in addition to providing quality feed and water, and a clean living environment. Urban homesteaders here in Florida will have numerous pests such as weasels, hawks, cranes, cats, dogs, snakes, raccoons, teenagers, homeless, and the odd code enforcement official to contend with.

     Rabbits are by far my favorite outside animal. They can live on a completely home-grown diet of grasses and weeds, or planted vegetation. Larger operations will probably appreciate he convenience of pellet, which is not prohibitively expensive. The meat and manure are high quality, and extra stock can be sold as pets.

     Chickens are hilarious little birds. I've read that a combination of cat food and day-old bread, supplemented with egg shells, can be enough food for them, though I've never tried it.

     Quail need an extremely high protein diet as naturally they would eat nothing but insects. I've heard that they thrive in areas high in cockroaches, so...

     Guinea Pigs, also called cuys, are good eats in parts of South America. Think of them as slightly smaller rabbits.

     Mice/Hamsters. I'm considering raising them just for their cat and dog food value, since they will eat rabbit pellet and kitchen scraps and be fine with that. Maybe ground hamster could become the next big chicken or fish feed additive?

     Pigeons, especially homing pigeons, are popular outdoor pets in West Florida. I've heard that they can free-range and return home very well. They eat similar feed as chickens.

     Fish can be kept in aquariums as pets, raised for meat value, or raised for their plant fertilization value (think Aquaponics). Crawdads, catfish, and tilapia are all raised successfully here in Florida. Perhaps one of the most covert urban animal operations could involve a decorative "koi" pond filled with catfish or tilapia (Guess what I'm building in my back yard!).

     Bees live very well here in Florida, the main consideration being the location and disguise of your hive(s). After all, no one can complain you have bees if they can't see the hives. Most urban and suburban areas of Florida have decorative flowering plants and trees, that produce year-round blooms.

Surprising Azolla Harvest

     The azolla in the newly built pond is finally growing up to the expectations claimed by numerous sources on the internet. Though the little pond is perhaps about 10 square feet of surface area, and even with the floating  planters, I was able to harvest a full pot of azolla last week and another pot of azolla today.
     I have been steaming to destroy bacteria (and  tadpoles) on the plants before draining and freezing into ice cube trays for ease of feeding to the rabbits. But it just brings up the good point, that if a person was starving, here is an extremely prolific food source for a survival garden.
     The only way to find the betta fish is by harvesting the azolla. It might not be a good idea to add this particular floating plant to decorative koi ponds. Now that my pond is up and running, I find myself wondering why not grow edible snails? They eat algae and won't disturb the floating planters, azolla, or fish.

Azolla, Azolla spp.

 Uses: Edible, Fodder, Fertilizer. Native to: The Cretaceous Period, worldwide.
     This floating water plant is actually a tiny, prehistoric fern with amazing properties. It fixes atmospheric nitrogen due to its symbiotic relationship with cyanobacteria, like an aquatic version of our more common legumes. Due to its nitrogen-fixation, it is also an extremely protein-rich plant, making it an excellent choice for home-grown fodder. In fact, there are very few land-based livestock animals that will not eat azolla, if any. Chickens, rabbits, goats, ducks, and cows are reported to gorge on this aquatic plant.
     Historically it has been used as a wetland green manure crop in the warmer parts of Asia. In the spring when taro or rice is planted in the boglands, the azolla would be innoculated to the water's surface. There the little ferns would fix nitrogen and proliferate, crowding out any competing algae or weeds via shading. Since the rice and taro have most of their foliage above water-level, it does not hinder their growth. The azolla will thrive, then self-mulch, then die down when the cooler weather comes. The farmers harvest some and shelter it for next year's use. The green manure properties of azolla make it possibly the six most valuable ferns on the planet.

A close-up of the roots which hang into the water.

     It's culture is simple - grow it in clean still or gentle water. Wind and water turbulence can fragment and destroy azolla, so sometimes floating beds are used. Like duckweed, under the right conditions it can become weedy if it escapes into waterways, so care should be taken to prevent escape. Since it provides it's own nitrogen, phosphorous can be a limiting factor to optimal growth. "The symptoms of phosphorous deficiency are red-coloured
fronds (due the presence of the pigment anthocyanin), decreased growth and curled
roots." A quick search of the webs reveals a superior organic source of high quality phosphorous can be made by burning animal bones at high temperatures to ashes. Never has a rocket mass heater in florida sounded more appealing!
     Azolla species can be used as a very nutritious survival food for humans, but it will need to be cooked to destroy any pathogens that might be living in the watery growing media. For animals, this compilated table shows it to have 16.5% crude protein and a bevy of other useful vitamins, like leucine and alanine. This Australian study lists many of the benefits of using azolla as a large-scale fodder source, but points out a simple drawback to commercial production - that contamination of the plantings by tiny freshwater shrimp can occur. This accidental animal protein renders the azolla illegal to sell as a feed source for ruminants in Australia, as they have strict legislation prohibiting animal proteins for ruminant consumption there. They also recommend the azolla be fed fresh or refrigerated, but within a week of harvest.
     A very nice synopsis of azolla research here.

Some free aquatic snail contamination.

I don't speak this language, but the video is very informative even muted.
