Garden & Ecology Notes
- Wildlife Value:
- birds, small mammals
- Deer Resistant:
- Yes
- Salt Tolerant:
- Yes
- Fragrant:
- Yes
- Fire Ecology:
- Fire adapted — tolerates or benefits from fire
- Fire Notes:
- Highly fire-adapted; resprouts vigorously from trunk and root crown after fire. Thick bark provides protection, and trees can produce epicormic shoots even after crown scorch.
Propagation & Germination
- Stratification:
- Cold/moist stratification required — 30–60 days
- Germination Time:
- 14–42 days
