Additional Information about Lobelia cardinalis 'Black Truffle'

Never, has a true, native cardinal flower been available with such deep, dark foliage and bright red flowers. The combination is stunning! We are happy to be working with native plantsman, extraordinaire, Peter Heus from West Virginia on this exciting new introduction. Black Truffle was selected for its nearly black foliage and bushy, upright habit. It’s a hummingbird magnet and so much more. If you’ve ever dreamed of a perennial coleus – this plant is your dream come true.

The foliage emerges nearly black with an oil-slick looking sheen to it. 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. - Plants Nouveau

Found throughout the Americas, cardinal flower occurs and in other locations with rich soil that is acidic to neutral and in filtered shade to full sun. While not a true perennial, Lobelia cardinalis propagates itself by offsets from axils at the basal foliage which form their own roots. When placed in a suitable site, cardinal flower will happily self-sow from seed.
