Garden & Ecology Notes
- Wildlife Value:
- birds, small mammals
- Deer Resistant:
- Yes
- Fragrant:
- Yes
- Fire Ecology:
- Fire adapted — tolerates or benefits from fire
- Fire Notes:
- Thick bark provides fire resistance; mature trees survive low to moderate intensity fires and resprout from protected buds.
Propagation & Germination
- Stratification:
- Cold/moist stratification required — 30–60 days
- Germination Time:
- 14–28 days
- Notes:
- Seeds germinate best after cold stratification; light not required but improves germination rates.
The above propagation data sourced from Claude AI
Pre-treatment: Seeds benefit from cool, moist stratification to break dormancy prior to germination. This can range from 60 to 90 days.
Establishment: There is some variation in the recommended stratification period between protocols. No germination rate provided in the protocols.
