I like to call this plant Psycho Coffee, because it's just more fun to say. I bought this several years ago from the Nature Coast Botanical Gardens, and it has thrived with no care at all. When I planted it back then I heeded the advice of IFAS and put it in the full shade, where it doubled in height and width and produced two seedlings. The seedlings also thrived in the full shade with no care, no watering, nothing.
Psycho Coffee is native to Florida, and Florida is its only home. It's hardiness is from 10B to 11, but it's growing well in the full shade in my 8A front yard. I happened to be at the Pasco County Earth Day celebration, and there was a gentleman there from the Florida Native Plant Society and he had some for sale, so I picked up another one and supported the Society. I have also spotted it growing as a huge bush at the entrance of the Boyd Hill Nature Preserve in St. Petersburg.
Psycho coffee propagates by seed, and I have found that the easiest way to propagate it is to dig up seedlings and put them where you want them.
The berries are edible, and have a large seed in them. They don't taste good. Flowers attract butterflies and the fruits attract birds. Some say that members of the coffee family contain a hallucinogen called dimethyltryptamine, but it is unknown if Psycho Coffee has that chemical. It's called Psychotria nervosa for the prominent ribbing on the leaves.
Definitely a keeper because edible fruit, beautiful flowers that bloom for months and attract pollinators, requires no care or watering, and loves full shade.
