Seed Storage
The storage behavior of this species is orthodox (desiccation-tolerant seeds), dry to 15 to 20% eRH, and store at -20°C.
Germination requirements
The seeds of this species are not dormant. Sterilize seeds before placing them on wet germination paper. Place seeds for two weeks at 4 ºC to germinate uniformly. Then germinate under an alternating temperature regime of 15/20 ºC (the higher temperature for 16 hours in light and the lower one for eight hours in dark).
