Garden & Ecology Notes

Wildlife Value:
birds, small mammals, bees
Deer Resistant:
Yes
Fall Color:
red, orange, purple
Fire Ecology:
Fire adapted — tolerates or benefits from fire

Soil Requirements

Soil Type:
sandy, acidic, nutrient-poor soil
pH:
4.0 - 5.5 (strongly acidic to acidic)
Drainage:
excellent drainage required
Moisture:
dry to moderate
Notes:
prefers open, sunny locations in native habitats

Propagation & Germination

Stratification:
Cold/moist stratification required — 60–90 days
Germination Time:
30–90 days
Notes:
Seeds require cold stratification and acidic conditions. Germination can be erratic and slow.

The above propagation data sourced from Claude AI

Pre-treatment: After sowing, seed trays are given a 1 month period of warm moist stratification with alternating day-night temperatures (optimum is 86/68°F though our greenhouse averaged about 75/65°F), followed by two months cool moist stratification at approximately 45-50°F.

Establishment: Seedlings are very slow growing. During establishment, it is important to keep the soil surface evenly moist. Do not allow media to remain saturated, dry out or develop a surface crust. Fungus gnats can become a problem and larval feeding may damage seedling roots, therefore treatment may be necessary.
