Worth knowing The momi fir of central and southern Japan grows to 50 m tall, with a broad conical crown of straight branches rising at about 20° above the horizontal. Wikipedia: Abies firma This source reports two treatments. Both are shown.

Grateful acknowledgement is made to Schumacher Seed Company of MA for a gift of fifteen species of this genus. All fifteen germ. at 70D albeit somewhat slowly with germination taking place in 5-10 weeks. Some gave slightly greater percent germination with light or in a 40-70D pattern, but, GA-3, OS, or OT had no significant effects. Some germ. at 40. A significant number of the seeds rotted indicating ,that they were dead.'but there was no simple way of detecting such seeds from outward appearance nor of separating them. The seeds of all .fifteen species were largely viable and producing healthy seedlings.
