[wikipedia] Range: Stachys floridana is a species of betony in the mint family, Lamiaceae. It is native to the United States, where its true native range is probably limited to Florida, but today it is known throughout the Southeast as an introduced species and common weed.[1][2] It occurs as far west as Texas,[2] and it has been recorded in California.[3] Its common names include Florida betony,[1] Florida hedgenettle,[4] and rattlesnake weed.[3] It has been called wild artichoke, but it is not closely related to artichoke.[5] The plant was the Florida Department of Agriculture's "Weed of the Month" for February 2010.[3] (contributed by Mary Ann Machi)
