Bidens Tickseed Wildflowers
Tickseed sunflower plants (Bidens aristosa) are in the Aster family and from the genus Bidens. As such, they are composite flowers made up of bright yellow ray flowers (what most people think of as "petals" on an aster) and small darker yellow or brown disc flowers clustered at the center. They are also typically called Bur Marigolds or Bearded Beggarticks. This fast-growing annual grows 4-5 feet (1-1.5 m.) tall. Hundreds of 2-inch (5 cm.) golden daisies with buttery tips and dark, fringed eyes smother fine foliage in summer. Tickseed sunflower plants typically have a lot of branches too. It may look like the plant has many little deep green-toothed leaves, but what you see are actually leaflets that make up a larger compound leaf. The plant prefers moist, open habitats. While they are considered invasive in some areas, their ability to colonize new and disturbed habitats makes them conspicuous plants in areas where other species might not be able to grow. In spring, you may see big patches of tickseed sunflowers along roads and in ditches where they take advantage of the run-off after rains. In fact, you may hear them called "ditch daisies." They are also found in wet soils around wetlands or in marshes.
