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 outdoors as soon as ripe in summer, will germinate following spring, germination impaired by dry storage
