ORGHPS Germination Guide: Requires scarification. Nick or rub between sheets of sandpaper. Requires soaking. Place in warm water until seeds swell, usually 24-48 hours. Discard water and any seeds that remain floating. This species needs special care. * 20°C x 6 months then 4°C x 3 months: pour hot water over seed and soak for up to 24 hours; 2) mechanical methods such as files or abrasive tools to physically score the seed to allow water entry; scarify with sulphuric acid; CAUTION: THIS CAN BE A DANGEROUS PROCEDURE
