Garden & Ecology Notes

Wildlife Value:
bees, butterflies, birds
Deer Resistant:
Yes
Fire Ecology:
Requires fire for germination
Fire Notes:
Resprouts from root crown after fire. Seeds require heat scarification or smoke exposure for germination; fire-following species in chaparral communities.

Soil Requirements

Soil Type:
sandy, well-drained, nutrient-poor soil
pH:
5.5 - 7.5 (slightly acidic to neutral)
Drainage:
excellent drainage required
Moisture:
dry to moderate
Notes:
native to coastal scrub and chaparral regions

Propagation & Germination

Stratification:
Cold/moist stratification required — 60–90 days
Scarification:
Seed coat scarification required before sowing
Germination Time:
14–60 days
Notes:
Hot water scarification or mechanical abrasion followed by cold stratification improves germination. Seeds may also respond to smoke treatment.

The above propagation data sourced from Claude AI

Pre-treatment: Cold-moist stratification for 30 days at 1–5°C (34–41°F).; then Scarify, then cold-moist stratify for 60 days.
