ORGHPS Germination Guide: Sow immediately, Either the viability of these seeds is short or the species propagates best with fresh seed. Stored seed might be coaxed into germination with temperature cycling and patience. Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again. * 20°C (light), then 4°C, then raise temperature slowly t20°C (dark), stand pot in 3 cm water
