Propagation & Germination

Stratification:
Cold/moist stratification required — 30–60 days
Germination Time:
14–30 days
Notes:
Seeds benefit from cold stratification for 4-8 weeks before sowing; germination occurs in 2-4 weeks at 15-20°C.

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. Requires light or the seed is very fine. Surface sow and expose to light. Germination if successful only when GA3 is used. * avoid pricking out individually, transplant seedlings in clumps
