Bidens, the common weed Spanish Needles, is one of the most important pollinator nectar source plants in our area. It is a host plant for certain butterflies.
Spanish Needles is also a source of an annoying seed that has a sharp end and little burrs on the other end that are also sharp. The starry seed clusters hold many of these needle-like seeds. Caught in dog fur, they are among the hardest seeds to remove. They also cling to clothing as you walk by. A source of seed for songbirds, they are best left to wild places.
Blue Curls, Trichostema dichotomum is an annual wildflower with a long season of bloom. The wild area pictured is also where I frequently see Twinflower, Dyschoriste oblongifolia in early spring.
