Resprouts vigorously from basal burl after fire. Adapted to chaparral fire regimes with 15-30 year intervals. Benefits from post-fire nutrient release.

Propagation & Germination

Stratification:
Cold/moist stratification required — 60–90 days
Scarification:
Seed coat scarification required before sowing
Germination Time:
30–180 days
Notes:
Scarification followed by cold stratification improves germination. Seeds often exhibit erratic and slow germination even under ideal conditions.

ORGHPS Germination Guide: Expose to fluctuation outdoor winter temperatures including freezing for 3 months. Gradually increase light and temperature in the spring. Requires light or the seed is very fine. Surface sow and expose to light. Requires scarification. Nick or rub between sheets of sandpaper. Requires soaking. Place in warm water until seeds swell, usually 24-48 hours. Discard water and any seeds that remain floating. * immerse in boiling water for 20 seconds
