Few people know that the rather small, slightly bitter leaves of this common "weed" of central and southern Florida, are cooked and eaten as a wild potherb. In fact, it has been cultivated as a vegetable in Kenya. At a recent Florida Herbal Conference, I could not find one plant-lover who knew what this common species was... so let's all get to know it. Medicinally, it is used in Ayurvedic and other traditional practices for many ailments. Externally, it has been used to treat cuts, wounds, skin diseases, headaches, boils, and lice. Be sure not to confuse it with the similar looking Purple Tassleflower, Emlia sonchifolia, which has clasping leaves, and is found in similar locations... it contains toxic pyrrolizidine... ew, gross. Butterflies and bees like to nectar at the flowers.
