Garden & Ecology Notes

Wildlife Value:
birds, butterflies, bees, small mammals
Fall Color:
yellow, orange, red
Fire Ecology:
Fire adapted — tolerates or benefits from fire
Fire Notes:
Vigorously resprouts from root crown after fire or top-kill. Benefits from periodic fire in prairie and savanna habitats.

Soil Requirements

Soil Type:
rich, well-drained loamy soil
pH:
5.5 - 7.5 (slightly acidic to neutral)
Drainage:
excellent drainage required
Moisture:
dry to moderate
Notes:
Prefers soils with good organic content

Propagation & Germination

Stratification:
Cold/moist stratification required — 90–120 days
Germination Time:
14–60 days
Notes:
Germination can be erratic even after stratification. Seeds benefit from cleaning of fruit pulp before stratification.

The above propagation data sourced from Claude AI

Pre-treatment: Seeds are soaked in a 3:1 water/3% hydrogen peroxide solution for 10 minutes, followed by a 48-hour running water rinse. Seeds are then placed in cold, moist stratification for 120 days at 1 to 3C in fine mesh bags buried in milled sphagnum peat moss in a ventilated container. Stratified seeds are washed weekly to remove mucilaginous material.

Establishment: There are variations in the pre-treatment protocol, with some suggesting a hydrogen peroxide rinse and others a simple water soak. The germination rate varies widely, from as low as 22% to as high as 90%. Some protocols suggest using semi-hardwood stem cuttings, but these have a lower germination rate.
