Propagation & Germination

Stratification:
Cold/moist stratification required — 30–60 days
Germination Time:
7–21 days
Notes:
Seeds germinate readily after cold stratification; surface sow and keep moist.

Pre-treatment: Dry storage of spring germinating seeds resulted in 95% germination. No pretreatment required for high germination rates in laboratory settings.

Establishment: Germination rates vary significantly between laboratory settings and direct field sowing, with much higher rates achieved in the lab. The plant is drought and heat tolerant, and persists under grazing pressure and extreme drought conditions.
