I have several first-year A. sikokianum and A. flavum seedlings which are now dormant, but have produced small, healthy corms. I've read that growth cycles can be artificially accelerated by refrigerating the dormant bulbs and starting them back into growth in a cool greenhouse before the natural season of growth. Is there a set length of time required for dormancy by each of these species? I know sikokianum is very early to break dormancy here, so I would assume its need for chilling hours to be pretty low, but I don't know a lot about flavum. Any advice would be appreciated.
