I'm trying to find rhubarb plants
Rhubarb is typically planted in early to mid-March from dormant pieces of the plant’s crown. Summer and fall planting is not recommended. Crowns are usually available in spring seed catalogs or sometimes as packaged material available at local nurseries and garden centers. Inspect packages well for firmness of the crowns as they dry out very easily and crowns from any source should be planted within a week or so to avoid drying. Occasionally in spring plants may be available at garden centers that have been started in pots but this tends to be the exception rather than the rule. The best chance of obtaining quality dormant crowns will be from mail-order sources or local nurseries in early spring.
