Garden & Ecology Notes

Wildlife Value:

bees, butterflies, birds, small mammals

Deer Resistant:

Yes

Fragrant:

Yes

Fire Ecology:

Fire adapted — tolerates or benefits from fire

Fire Notes:

Resprouts vigorously from burl after fire. Adapted to chaparral fire regime with 30-100 year return intervals. Fire stimulates flowering and seed germination.

Soil Requirements

rocky, well-drained, nutrient-poor soil

pH:

5.5 - 7.0 (slightly acidic to neutral)

Drainage:

excellent drainage required

Moisture:

dry to moderate

Notes:

native to chaparral regions with poor soil fertility

Propagation & Germination

Stratification:

Cold/moist stratification required — 60–90 days

Scarification:

Seed coat scarification required before sowing

Germination Time:

30–120 days

Notes:

Seeds have thick seed coats requiring scarification plus cold stratification. Germination can be slow and erratic even with proper treatment.
