Garden & Ecology Notes
- Wildlife Value:
- birds, small mammals, pollinators
- Deer Resistant:
- Yes
- Fire Ecology:
- Fire adapted — tolerates or benefits from fire
- Fire Notes:
- Resprouts vigorously from basal burls after fire. Common component of post-fire succession in montane coniferous forests.
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:
- Commonly found in rocky or gravelly soils.
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 may exhibit prolonged dormancy and erratic germination even with treatment.
The above propagation data sourced from Claude AI
Pre-treatment: Cuttings were dipped into a 5% bleach solution for 10 seconds and a fresh basal cut was made just prior to dipping into Hormex #8 rooting hormone (0.8% IBA in a talcum powder base)
Establishment: Mature, 1-year-old cuttings of good vigor and caliper should be collected as late as possible in the fall. Cuttings were collected at Crater Lake just ahead of snowfall in October; where early snowfall and road closure is not a problem cuttings should be collected even later; into November and December.

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
