Garden & Ecology Notes
- Wildlife Value:
- birds, small mammals
- Deer Resistant:
- Yes
- Fragrant:
- Yes

- rocky, well-drained, nutrient-poor soil
- pH:
- 6.0 - 8.0 (neutral to slightly alkaline)
- Drainage:
- excellent drainage required
- Moisture:
- dry to moderate
- Notes:
- commonly found in arid, semi-desert regions
Propagation & Germination
- Stratification:
- Warm then cold/moist stratification (double dormancy) — 90–120 days
- Germination Time:
- 30–120 days
- Notes:
- Seeds have double dormancy requiring warm stratification followed by cold. Germination is often erratic and may take over a year.

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