Hibiscus 'Cranberry Crush'

Hibiscus 'Cranberry Crush' | Also known as: Rose of Sharon 'Cranberry Crush' | Rating: 5 votes | Print / Pdf

Hibiscus 'Cranberry Crush' is also known as Swamp mallow 'Cranberry Crush’. This new variety is something rather special. It's low growing with toothed leaves rather like a maple, and large deep red flowers that grow from several points on each stem, rather than just from the top of each stem like most varieties, meaning that you get an abundance of flowers. The blooms grow up to 8 inches across making them a very impressive sight, the petals have a slightly ruffled look to them and they overlap each other. Hummingbirds are particularly attracted to these flowers.
