Spreading Dogbane
Spreading dogbane’s early‑summer nectar is a steady resource for native bees, wasps, and small butterflies, and the plant’s dense, milky sap makes it an important host for several specialist insects that have adapted to its chemistry. In dry, open habitats—roadsides, sandy clearings, and woodland edges—it helps anchor thin soils, and its leafy structure offers shelter for ground‑nesting pollinators moving between patches of bloom.
A native perennial, spreading dogbane grows one to four feet tall, with simple, oval, toothless leaves two to four inches long, often edged with a slight wave. The flowers appear in loose groups of two to ten. Each is only about a quarter inch wide—white, bell‑shaped, and striped with pink, the five petals fused into a delicate cup. You’ll find the plant in dry, sunny places along roads and the margins of deciduous woods.
