www.rarexoticseeds.com - "No pre-treatment is required. Cover the seeds with 1/4" of your soil mixture. Keep damp soil, not soaking wet. Keep pot in warm situation 20ðC/68ðF, 24ðC/75ðF. Germination can take several months."

BackyardGardener - Seeds do not require pretreatment. Surface sow seeds and do not cover with growing medium. The medium should be moist, and we would recommend that you cover the seed container with a piece of glass or clear plastic. Temperature should be kept at approximately 70 degrees F. Seeds should receive diffused light. Once some of the seeds have germinated air should be admitted gradually to prevent damping off.

B&T World Seeds - Sow seeds on the surface of a moist peaty seed sowing mix or compost. Use a translucent cover to allow light in and to keep the compost humid and warm (do not place in direct sunlight). Keep temperatures around 25ðC (77ðF). Seeds will usually germinate in 15-90 days, even under good conditions germination may be erratic.
