Garden & Ecology Notes
- Wildlife Value:
- birds, small mammals, seed source
- Fragrant:
- Yes
- Fire Ecology:
- Fire adapted — tolerates or benefits from fire
- Fire Notes:
- Thick bark provides moderate fire resistance in mature trees. Can survive low to moderate intensity surface fires, though seedlings and saplings are fire-sensitive.
Propagation & Germination
- Stratification:
- Cold/moist stratification required — 21–60 days
- Germination Time:
- 14–60 days
- Notes:
- Seeds germinate best with light exposure at temperatures of 15-20°C after cold stratification. Fresh seed germinates better than stored seed.

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