Dear All, I'd like to get some cultural tips on the above mentioned species. With F. imperialis i had no luck keeping them longer than 1-2 years, they flower well the first year if planted early as possible, but eventually they die out. They just not emerging next year. When i dud up the place the bulbs disappear. With F. persica the bulbs grow for many years, but even with a well sized bulb they send up shoots with aborted buds, but in the first year they flower well, so i think the bulb needs a special treatment not to abort the buds. Do they need a special soil? Thank you. Regards, Janos Z5a, Hungary
