From Walter's Gardens:
This variety combines the deep wine-purple, maple-like foliage of 'Perfect Storm' and the scarlet red, 8-9″ flowers of 'Cranberry Crush'. Like many perennials with purple foliage, this one needs to be exposed directly to UV light (grown in full sun) to achieve the darkest foliage color.
Since this variety is an indeterminate bloomer (has buds at several nodes up the stem), it blooms for an extended period from midsummer into early fall.
These North American native plants bring massive, tropical-looking flowers all the way to zone 4. Although later to emerge than most perennials in spring, these are fast growing plants capable of adding an inch of new growth a day. Excellent at brightening up end of season gardens.
