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. Use repeated cycles of 20°C, then 4°C for 3 months each. Germination is very prolonged. * dry storage is fatal; grow indoors for 3 cycles, then put outdoors in Jan. for April germination
