What “Hibiscus” Means on Plant Tags

On plant tags and in search results, “hibiscus” can point to several different plants. Tropical hibiscus is usually grown as a warm patio plant or bright indoor overwintering plant. Hardy hibiscus can disappear to the ground in winter and return from the crown. Rose of Sharon is a deciduous woody shrub.

Winter Behavior Is the Main Split

A tropical hibiscus usually needs protection before frost and often before repeated cool nights. Hardy hibiscus and Rose of Sharon behave differently: they can be outdoor landscape plants in suitable zones, but their leaves and stems may still change dramatically with the season.
