- Like other manzanitas, it can resprout from burls after fire and seeds may benefit from fire or smoke exposure for germination.
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 hard seed coats requiring scarification; fire or smoke treatment may improve germination rates as with other Arctostaphylos species.

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
