Editing Erythronium (section)

== Cultivation and uses ==
Erythroniums are widely grown as [[ornamental plant]]s, with numerous [[Hybrid (biology)|hybrids]] and [[cultivar]]s having been selected for garden use. Popular cultivars include [[Erythronium 'Pagoda'|''Erythronium'' 'Pagoda']], ''E.'' 'Sundisc', ''E.'' 'Joanna', ''E.'' 'Kondo', ''E.'' 'Citronella', ''E. californicum'' 'White Beauty', and ''E.'' 'Rosalind'. Propagation is best by seed in autumn or by division of bulbs, depending on species. Some species propagate vegetatively. The plant is also great as a ground cover, as it will spread over several years.

Erythroniums are woodland plants and require rich soil, full of organic matter. Soil should be evenly moist and slightly acidic. They prefer shade or filtered sunlight.<ref>{{Cite book |last=Johnson |first=Lorraine |title=100 Easy-to-Grow Native Plants |publisher=Firefly Books Ltd. |year=1999 |isbn=1-55209-327-1 |location=Buffalo, New York |publication-date=1999 |pages=110 |language=English}}</ref>

The [[bulb]] is edible as a [[root vegetable]], cooked or dried, and can be ground into [[flour]].  The leaves can also be cooked as a [[leaf vegetable]]. In [[Japan]], ''Erythronium japonicum'' is called ''[[katakuri]]'', and the bulb is processed to produce [[starch]], which is used for food and other purposes.
