Fritillaria - Description and Uses

Description and Uses

They often have nodding, bell- or cup-shaped flowers, and the majority are spring-flowering. Most species' flowers have a rather disagreeable scent, often referred to as "foxy," like feces or wet fur. The Scarlet Lily Beetle (Lilioceris lilii) eats fritillaries, and may become a pest where these plants are grown in gardens.

Several species (such as F. cirrhosa and F. verticillata) are used in traditional Chinese cough remedies. They are listed as chuān bèi (Chinese: 川貝) or zhè bèi (Chinese: 浙貝), respectively, and are often in formulations combined with extracts of Loquat (Eriobotrya japonica). F. verticillata bulbs are also traded as bèi mǔ or, in Kampō, baimo (Chinese/Kanji: 貝母, Katakana: バイモ). F. thunbergii is contained in the standardized Chinese herbal preparation HealthGuard T18, taken against hyperthyroidism.

Most fritillaries contain poisonous alkaloids such as imperialin; some may even be deadly if ingested in quantity. But the bulbs of a few species – e.g. F. affinis and F. pudica – are edible if prepared correctly. They are not generally eaten in large amounts however, and their edibility is therefore still somewhat debatable.

At least one species, F. assyrica, has a very large genome. With approximately 130,000,000,000 base pairs, it equals the largest known vertebrate animal genome known to date – that of the Marbled Lungfish (Protopterus aethiopicus) – in size.

The emblematic and often unusually-colored fritillaries are commonly used as floral emblems. F. meleagris (snake's head fritillary) is the county flower of Oxfordshire, UK, and the provincial flower of Uppland, Sweden, where it is known as kungsängslilja ("Kungsängen lily"). In Croatia this species is known as kockavica, and the checkerboard pattern of its flowers is held to be the inspiration for the šahovnica pattern on Croatia's coat of arms. F. camschatcensis (Kamchatka fritillary) is the floral emblem of Ishikawa Prefecture and Obihiro City in Japan. Its Japanese name is kuroyuri (クロユリ), meaning "dark lily". F. tenella is the floral emblem of Giardino Botanico Alpino di Pietra Corva, a botanical garden in Italy.

Fritillaria is also used as an herb in Traditional Chinese Medicine, known by the Chinese name Chuan Bei Mu, and Latin, Bulbus fritillariae cirrhosae. In one study Fritillaria modulated airway inflammation by suppression of cytokines, IgE, histamine production, and eosinophilic accumulation along with increased interferon-gamma production in tests on lung tissue.
