Purple Swamp Rose Mallow (Hibiscus moscheutos) is a multi-stemmed, herbaceous, woody perennial that is native to the eastern United States and naturally grow along creek banks and wetlands. Purple varieties including ‘Plum Crazy’ present a range of pink and lavender toned, gigantic flowers that strongly contrast with their rich green foliage. Purple varieties are less commonly found in the wild and are mostly found in cultivars.

Plant bare-root shrubs during the more excellent spring or fall months, from November through April. Dig a hole twice as wide as the root system and slightly more profound than its height. Position the shrub so that the top of the roots is level with the ground, and put back the soil dug over the roots. Apply a 2-3 inch layer of mulch around the base to retain moisture and suppress weeds, ensuring the mulch does not touch the shrub's stem. Water regularly, especially during the first year, to establish strong roots. Prune shrubs as needed to promote healthy growth. In the spring, fertilize with a balanced, slow-release fertilizer suited to the specific needs of the shrub.
