No matter what you call it — Beggarticks, Spanish needle, monkey’s lice — Bidens alba is likely the most underappreciated of all Florida’s native wildflower. It is often considered a weed because it reproduces so prolifically, but it is a wonderful native wildflower for attracting pollinators. It is a larval host for the Dainty sulphur butterfly and a favorite nectar source for a myriad of butterflies including. In Florida, it is the third most common source of nectar for honey production. Its young leaves and flowers are edible.

Beggarticks blooms are comprised of five to eight white ray florets surrounding many yellow tubular disk florets. Leaves begin simple and oppositely arranged. As they mature, they become compound with lobed leaflets that have hairy undersides and toothed marginsSeeds have two barb-like bristles on the end that stick to clothing, hair and animal fur.

The genus name Bidens comes from the Latin words bis, meaning “two,” and dens, meaning “tooth.” The species epithet alba refers to the white ray florets.
