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 @ 4°C for 3 weeks, then place at 20°C. * seed very poisonous, wash hands after handling; longer viability than other aconitum seed, 20°C x 4 weeks, -7°C x 6 weeks, 10°C for germination
