Garden & Ecology Notes
- Wildlife Value:
- birds, small mammals
- Salt Tolerant:
- Yes
- Fall Color:
- yellow
- Fire Ecology:
- Fire adapted — tolerates or benefits from fire
- Fire Notes:
- Resprouts vigorously from the root crown following fire. Thin bark makes young trees susceptible, but mature trees tolerate low-intensity fire.

Propagation & Germination
- Stratification:
- Warm then cold/moist stratification (double dormancy) — 60–90 days
- Germination Time:
- 14–60 days
- Notes:
- Seeds benefit from warm stratification (60 days) followed by cold stratification (60-90 days). Germination can be erratic.
The above propagation data sourced from Claude AI
Pre-treatment: Seeds are cold stratified for 60 to 90 days and germinated at 21 C (69.8 F). Some protocols also suggest imbibing seeds in water for 2 days. Seeds are sown outdoors in nursery beds in the fall soon after collection and cleaning for natural stratification.
Establishment: Seeds are collected from various sources, including wild collection during fall months, parks in October, and local people who collect within a 50 mile radius of the nursery. The fruit is an orange to reddish, purplish, or black drupe that contains a single seed or nutlet. The hard, bony seeds are cream-colored and approximately 5.5 mm (0.22 in) in diameter at maturity.
