Rank Reasons
Apocynum androsaemifolium is a perennial herb that is native to hardwood and coniferous woodlands, clearings, canyons, grasslands, river terraces, and disturbed sites throughout North America. Potential threats to this species include development, road maintenance, invasive species, and other threats in some places. With a large range extent, more than 2000 occurrences, abundant habitat, and broad habitat preferences, this species is considered secure.
Range Extent Comments
Apocynum androsaemifolium is widespread in North America from Alaska to Newfoundland, Canada, south throughout most of the United States to northern Mexico (FNA 2023). Range extent was estimated using herbarium specimens and photo-based observations documented between 1994 and 2025 (GBIF 2025, iNaturalist 2025, RARECAT 2025, SEINet 2025).
Occurrences Comments
By applying a 1 km separation distance to herbarium records and photo-based observations documented between 1994 and 2025, there are estimated to be more than 2000 occurrences rangewide (GBIF 2025, iNaturalist 2025, RARECAT 2025, SEINet 2025).
Threat Impact Comments
Although threats are not widely documented, Apocynum androsaemifolium is potentially threatened by development, road maintenance, invasive species, and other threats in some places. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, tolerance of disturbance, and affinity for typically abundant habitats, as well as no obvious intrinsic vulnerabilities.
Ecology & Habitat

Habitat

Apocynum androsaemifolium grows in "hardwood and coniferous forests and woodlands, clearings, mountain canyons, river terraces, old fields, pastures, roadsides" (FNA 2023).
