Did You Know?
This species has been used to bring toothache releif.
Harbinger-of-spring (Erigenia bulbosa) is a small (5-15cm tall) herb in the carrot family.
Uncommon but not rare; some cause for long-term concern due to declines or other factors.
Rich, mixed hardwood forests in lowlands, costal plains, and mountain valleys
Flowers March - April
Harbinger-of-spring's lowland forest habitats have been fragmented by logging and invaded by exotic species. Although the species' worldwide population is considered secure, it is quite rare in Pennsylvania and other states at the edge of its range.
Loss of bottomland forest to agriculture and unsustainable forestry has severely impacted many of the forests where this plant may have existed. Conserving high-quality bottomland forests where this plant normally grows is key to the protection of this species.
