- Wildlife Value:
- bees, birds
- Deer Resistant:
- Yes
- Fragrant:
- Yes
- Fire Ecology:

- well-drained, sandy to loamy soil
- pH:
- 5.5 - 7.0 (slightly acidic to neutral)
- Drainage:
- excellent drainage required
- Moisture:
- dry to moderate
- Notes:

Propagation & Germination
- Stratification:
- None required
- Scarification:
- Seed coat scarification required before sowing
- Germination Time:
- 14–42 days
- Notes:
- Seeds require hot water treatment (near boiling) or mechanical scarification to break hard seed coat dormancy. Germination is rapid once dormancy is broken.
