Seed Storage
The storage behavior of this species is orthodox (desiccation-tolerant seeds); dry to 15-20 % eRH and stored 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 in 4ºC germinate uniformly. Then germinate under an alternating temperature regime of 15/25 ºC (the higher temperature for 16 hours of light and the lower one for 8 hours of dark).
