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. Expose to fluctuation outdoor winter temperatures including freezing for 3 months. Gradually increase light and temperature in the spring. Pulpy coat inhibits germination. Remove by soaking and rinsing in clean water for approximately 7 days. Discard water. * remove pulpy coat with detergent washes; germination unlikely if seed dried by just 20%, store seeds @ 4°C
