Garden & Ecology Notes
- Wildlife Value:
- bees, butterflies, birds
- Deer Resistant:
- Yes
- Fragrant:
- Yes
- Fire Ecology:
- Fire adapted — tolerates or benefits from fire
- Fire Notes:
- Resprouts from root crown after fire; seeds may benefit from heat scarification in post-fire conditions.
Propagation & Germination
- Stratification:
- None required
- Scarification:
- Seed coat scarification required before sowing
- Germination Time:
- 14–30 days
- Notes:
- Scarification improves germination; soak seeds in warm water or nick seed coat. Direct sow in fall for best results.
The above propagation data sourced from Claude AI
Pre-treatment: Cold-moist stratification for 30 days at 1–5°C (34–41°F).; then Scarify, then cold-moist stratify for 60 days.
Notes: Seeds may require light for optimal germination.
