General / Habitat
- Perennial Herb
- Common in moist forest, avalanche tracks, and streambanks
- Low to subalpine elevations
Key Identifying Characteristics
- Form: 0.5-1 m tall, sometimes taller, branched, sometimes zig-zagging at leaf nodes
- Leaves: Oval, 5-14 cm long, clasping at base, hairless beneath, margins sometimes having irregular spacing of teeth
- Flowers: Greenish white, bell-shaped, hang individually or in twos from kinked stalk in leaf axil
- Fruit: Yellowish red to purple oblong berries
Lookalikes
- When young, resembles Veratrum viride (Indian hellebore), one of the most deadly-poisonous plants in our region
- Can be very easily confused with a number of similar lilies when non-reproductive:
- Mainthemum racemosum or Mainthemum stellata (False Solomon’s seal or Star-flowered false Solomon’s seal) - unbranched, leaves don’t clasp
- Streptopus roseus (Rosy twisted stalk)– typically unbranched, leaves shiny beneath, leaf margin/edge and nodes with hairs
- Disporum hookeri (Hooker’s fairybells)- hairs on upper leaf surface and along stem
- If there are flowers, check that they are borne on kinked stems in leaf axils for Streptopus amplexifolius
- Streptopus roseus flowers are pink and borne on curved stems
Interesting Characteristics
- Young shoots and roots eaten by some coastal peoples for medicinal purposes, but berries were generally considered to be poisonous
