Cultivation details
Landscape Uses:Border, Container, Massing, Seashore, Specimen, Woodland garden. Easily grown in a moderately fertile soil[90]. Prefers a heavy soil without any disturbance, not even hoeing[1, 42]. Requires a well-drained soil and a sunny position[42, 90, 200] or the shade of deciduous trees or shrubs[90]. Succeeds in drier soils and is drought tolerant once established[190]. Plants succeed in most fertile soils, avoiding pure chalk, heavy clay and boggy sites[233]. The dormant bulbs are very hardy and will withstand soil temperatures down to at least -10°c[214]. A very ornamental plant, there are some named varieties[233]. The flowers smell of wet fur and garlic[245]. Bulbs should be planted 10 - 12 cm deep in July[1] on their side with sharp sand beneath them to ensure that they do not rot[42, 200]. Special Features: Attractive foliage.
Propagation
Seed - best sown as soon as ripe in a cold frame, it should germinate in the spring[1]. Protect from frost[134]. Stored seed should be sown as soon as possible and can take a year or more to germinate[134]. Sow the seed quite thinly to avoid the need to prick out the seedlings. Once they have germinated, give them an occasional liquid feed to ensure that they do not suffer mineral deficiency. Once they die down at the end of their second growing season, divide up the small bulbs, planting 2 - 3 to an 8cm deep pot. Grow them on for at least another year in light shade in the greenhouse before planting them out whilst dormant. Division of offsets in August[1]. The larger bulbs can be planted out direct into their permanent positions, but it is best to pot up the smaller bulbs and grow them on in a cold frame for a year before planting them out in the autumn.

Have grown these bulbs for 40 years, splitting clumps occasionally and had 150 blooms one year. This year no yellow ones, and only a few orange, rest blind. Help would be appreciated. Sarah Hurley

I live in Zone 5, can the bulbs be stored indoors during the winter, and any suggestions for storage. Thank you

According to the "Botanica" (a book) Fritillaria imperialis is suited to zones 4-9 (zone 4 is -34 to -29 Celcius or -30 to -20 F). So it should be ok outside, I'd experiment with some of them outside. It is even possible it won't like being stored inside since it's upper favored level is zone 9, still below freezing in winter. I have no personal experience with this particular plant.
