Summary

Apocynum androsaemifolium, commonly known as Spreading Dogbane, is a deciduous perennial herb that is native to a variety of habitats including open woodlands, prairies, fields, and along streams throughout North America. It typically grows to a height of 2-3 feet (0.6-0.9 meters) and spreads to about 3 feet (0.9 meters). The plant has a bushy form with branching stems and exudes a milky sap when broken. Spreading Dogbane blooms in the summer, producing clusters of small, bell-shaped pink to white flowers that are particularly attractive to butterflies and other pollinators.

The plant is valued for its ability to attract beneficial insects and for its ornamental qualities, including its delicate flowers and its reddish-brown fall foliage. It is used in naturalized areas, wildflower gardens, and as part of pollinator-friendly plantings. Spreading Dogbane prefers full sun but can tolerate partial shade, and it adapts to a range of soil types, provided they are well-drained. It is important to note that all parts of the plant are toxic if ingested, and it can spread aggressively by rhizomes, potentially becoming weedy in a garden setting.CC BY-SA 4.0
