Wonderful in the perennial border and perfect for rain gardens, this cardinal flower is sure to stand out with its dramatic, dark chocolatey-purple foliage and bold red flowers. Superior to other dark-foliaged Lobelias on the market, 'Black Truffle' holds this deep color throughout the growing season. As the summer months go on and the heat turns up, the foliage turns shiny maroon and stays that way until the cardinal red flowers appear. The foliage lasts from May to a hard frost and will give you months of enjoyment as the hummingbirds and butterflies frequent it often. (Source: North Creek Nurseries)
