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.

Soil Requirements

Soil Type:
rich, well-drained loamy soil
pH:
6.0 - 8.0 (slightly acidic to slightly alkaline)
Drainage:
tolerates poor drainage
Moisture:
dry to moderate
Notes:
adaptable to various soil types

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.
