Propagation & Germination
- Stratification:

- Germination Time:
- 30–90 days
- Notes:
- Seeds require cold stratification for 60-120 days; germination occurs in spring after soil warms.
Pre-treatment: Seeds are cold stratified for 30 to 150 days. Fresh seeds are sown by hand into prepared field beds during October. Seed may be floated in water to help determine viability. Seed that floats is discarded, while the seed that sinks is retained for planting.
Establishment: Seeds are collected from various sources, including local people who collect within a 50 mile radius of the nursery, and established natural stands within the confines of Stones River National Battlefield. The general distribution of C. ovata is within temperate deciduous forests of central and eastern North America.
