Garden & Ecology Notes

Wildlife Value:
birds, bees, butterflies, small mammals
Fragrant:
Yes
Fall Color:
red, orange
Fire Ecology:
Fire adapted — tolerates or benefits from fire
Fire Notes:
Resprouts vigorously from rhizomes following fire. Often increases in abundance in fire-maintained prairies and savannas.

Soil Requirements

Soil Type:
rich, well-drained loamy soil
pH:
5.5 - 7.0 (slightly acidic to neutral)
Drainage:
good drainage required
Moisture:
dry to moderate
Notes:
prefers open woods and thickets

Propagation & Germination

Stratification:
Cold/moist stratification required — 60–120 days
Scarification:
Seed coat scarification required before sowing
Germination Time:
30–180 days
Notes:
Scarification followed by cold stratification improves germination. Germination can be erratic and may occur over multiple seasons.

The above propagation data sourced from Claude AI

Pre-treatment: Mix seed with equal amounts of vermiculite and lightly dampen in a plastic bag or container. Store for 3-4 months in a cold room of 34-36 degrees F. Alternatively, scarify in concentrated sulfuric acid for 45 minutes followed by cold stratification in moist growing medium for 3 months.

Establishment: Seed is collected by hand from nursery stock. The plant flowers from approx. May 15 to June 10. Seed is harvested June 22. Alternatively, seeds were collected in Natchez Trace Parkway close to Jackson, Mississippi by PMC staff in July 1991 and June 1992.

ORGHPS Germination Guide: Use repeated cycles of 20°C, then 4°C for 3 months each. Germination is very prolonged. Pulpy coat inhibits germination. Remove by soaking and rinsing in clean water for approximately 7 days. Discard water. * soak in hot water for 24 hours to scarify
