Bidens alba

Plant portrait: Small white-rayed flowers with golden centers on an airy, freely branching plant.

Garden rhythm: Warm-season annual or short-lived perennial depending on winter; sun to part sun, adaptable.

Garden companions: Nectar and pollen for a wide range of insects; seeds can travel on fur and clothing.

Worth noticing: The name is Bidens, not “Biden's”—from Latin words referring to the seed's two teeth.
