Acalypha chamaedrifolia
Acalypha chamaedrifolia, the red cat's tail, is a species of flowering plant in the family Euphorbiaceae, native to southern Florida and the islands of the Caribbean. It performs best in a loam-less potting mixture. As its synonym Acalypha hispaniolae it gained the Royal Horticultural Society's Award of Garden Merit in 2002, but this seems to have been rescinded.
