The above propagation data sourced from Claude AI
Pre-treatment: Seeds are soaked for 24 hours in a 1mmol solution of ethephon, then placed in cold storage for four weeks. Alternatively, GA3 at 1mM concentration can be used.
Establishment: E. tennesseensis is endemic to Tennessee, growing in limestone soils in cedar glade habitat. Germination was found to be greater in light than dark according to one protocol.
