Bidens is the common name given to a group of about 200 flowering plants of various sizes and colors of both perennials and annuals. These plants look something like coreopsis and are, indeed, related to them. These members of the Asteraceae family grow naturally throughout the southern United States and as far south as Guatemala. This family of plants earned these names thanks to their clinging seeds, which look something like ticks and stick to clothing and fur to spread easily. The plants’ botanical name comes from the Latin words, bis and dins, which mean (respectively) twice and tooth. Its species name, ‘aurea’, means golden.
