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 * dry storage for > 6 months is fatal; use E in repeated cycles if seed does not germinate
