Garden & Ecology Notes

Wildlife Value:

bees, native pollinators

Deer Resistant:

Yes

Fire Ecology:

Fire adapted — tolerates or benefits from fire

Fire Notes:

Typical of sagebrush steppe species, can resprout from root crown after fire. Benefits from occasional fire disturbance in native habitats.

Propagation & Germination

Stratification:

Cold/moist stratification required — 30–60 days

Scarification:

Seed coat scarification required before sowing

Germination Time:

14–30 days

Notes:

Seed coat scarification improves germination success. Legume seeds benefit from brief hot water treatment or mechanical scarification before cold stratification.
