    Bidens pilosa is a perennial that grows everywhere here in Florida. It's a profuse re-seeder and I find it popping up in my flower beds every year. To most gardeners this plant is considered a weed to be immediately removed while others consider it a beautiful wildflower that attracts many butterflies and bees to the garden. The seeds resemble black needles with barbed hooks at the ends. Seeds are dispersed by the wind as well as by attaching themselves to clothing or fur as people and animals brush against them. Bidens pilosa produces thousands of seeds that remain viable for up to 5 years so if you don't want a mass of these plants in your garden it's best to dig them out before they set seed.
