Garden & Ecology Notes

Wildlife Value:

bees, native pollinators

Deer Resistant:

Yes

Fire Ecology:

Fire adapted — tolerates or benefits from fire

Fire Notes:

Resprouts from root crown after fire. Common in fire-adapted sagebrush steppe communities where periodic fires promote herbaceous plant vigor.

Propagation & Germination

Stratification:

Cold/moist stratification required — 30–60 days

Scarification:

Seed coat scarification required before sowing

Germination Time:

14–45 days

Notes:

Scarification improves germination rates. Seeds have hard coats typical of legumes and benefit from mechanical or chemical scarification before cold stratification.
