Garden & Ecology Notes

Wildlife Value:
birds, squirrels, bees, hummingbirds
Deer Resistant:
Yes
Fall Color:
yellow, golden
Fire Notes:
Thin bark makes it susceptible to fire damage; does not resprout well after top-kill.

Soil Requirements

Soil Type:
rich, well-drained loamy soil
pH:
5.5 - 7.5 (slightly acidic to neutral)
Drainage:
good drainage preferred
Moisture:
consistently moist
Notes:
prefers deep, fertile soils

Propagation & Germination

Stratification:
Cold/moist stratification required — 60–90 days
Germination Time:
15–60 days
Notes:
Seeds have low viability; best results with fresh seed and cold-moist stratification. Light may improve germination.

The above propagation data sourced from Claude AI

Pre-treatment: Seeds are either sown in outdoor nursery beds in the fall soon after collection and cleaning for natural stratification or placed in cold moist stratification for 70 days.

Establishment: Seeds are collected from various locations, including Great Smoky Mountains National Park, Cumberland Gap National Historical Park, National Capital Parks-East, Shenandoah National Park, George Washington Memorial Parkway, and local sources in south central Missouri. The general distribution of Liriodendron tulipifera ranges from Vermont to southern Michigan, Missouri and south to Florida and Louisiana, and is also found in temperate deciduous forests of the eastern United States.

ORGHPS Germination Guide: Use repeated cycles of 20°C, then 4°C for 3 months each. Germination is very prolonged. Requires darkness. * empty seed coats are undetectable; 5% germination is normal
