Not only are the flowers a deep red colour but Midnight Marvel offers win-purple foliage as well.
Hardy hybrid hibiscus is a vigorous, sturdy, erect but sometimes shrubby, woody-based perennial that typically grows to 4-8’ tall. These hybrids are winter hardy to zone 4 which distinguishes them from the many tropical to semi-tropical hibiscus on the market today. Each of their beautiful disc-shaped flowers can measure 6-10” across. Individual flowers remain in bloom for only one day, but one or more flowers usually open each day, in succession, over a long mid-summer to early fall sometimes to first frost bloom period.
Their one drawback is that they come into leaf very late in the season – around June in some cases. But the very lateness of the hibiscus is its strong point – especially when it comes to the flowers. That being said, each plant can produce up to 250 flowers per growing season!
