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. Seed germinates within 3 months Requires light or the seed is very fine. Surface sow and expose to light. * dry storage for > 6 months is fatal
