Garden & Ecology Notes
- Wildlife Value:
- birds, bees, butterflies
- Deer Resistant:
- Yes
- Fire Ecology:
- Fire adapted — tolerates or benefits from fire
- Fire Notes:
- Resprouts vigorously from basal burls after fire. Seeds germinated by heat and smoke from wildfires, typical of chaparral-adapted manzanitas.
Soil Requirements
- Soil Type:
- sandy, acidic, nutrient-poor soil
- pH:
- 5.5 - 7.0 (slightly acidic to neutral)
- Drainage:
- excellent drainage required
- Moisture:
- dry to moderate
- Notes:
- Prefers rocky or sandy slopes in native habitat
Propagation & Germination
- Stratification:
- Cold/moist stratification required — 60–90 days
- Scarification:
- Seed coat scarification required before sowing
- Germination Time:
- 30–180 days
- Notes:
- Scarification by fire or mechanical abrasion significantly improves germination rates. Seeds may remain dormant for extended periods.

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
