Garden & Ecology Notes

Wildlife Value:

bees, butterflies, birds

Deer Resistant:

Yes

Fragrant:

Yes

Fire Ecology:

Requires fire for germination

Fire Notes:

Seeds require fire or heat scarification for germination. Plants resprout weakly or not at all; populations regenerate primarily from seed bank following fire.

Soil Requirements

Soil Type:

sandy, well-drained, nutrient-poor soil

pH:

6.0 - 7.5 (slightly acidic to neutral)

Drainage:

excellent drainage required

Moisture:

dry to moderate

native to coastal chaparral regions

Propagation & Germination

Stratification:

Cold/moist stratification required — 60–90 days

Scarification:

Seed coat scarification required before sowing

Germination Time:

30–90 days

Notes:

Seeds benefit from hot water treatment or scarification followed by cold stratification. Smoke treatment may enhance germination.
