Fritillaria is a genus that consists of about 100 species. They are native to the temperate regions of the Northern hemisphere. The name is derived from the Latin name for a dice-box (fritillus) and probably refers to the checkered pattern, quite often of chocolate brown and greenish-yellow, that is common in the flowers of many species.
Imperialis & persica type bulbs require soil that drains quickly and thoroughly. All fritillaria should be planted as early in the Fall-season as possible: the imperialis & persica types will start to develop roots inside the packaging which can result in damage during planting and the meleagris and michailovskyi species tend to dry out when stored for too long.
