Cardinal Flower (Lobelia cardinalis) 'Black Truffle' is a dark-leaved cultivar of the species plant. I obtained this plant in 2013. In 2014 it returned, but the dark leaf coloring was remarkably diminished. It is possible that the original plant did not survive, but that it reseeded and in doing so, reverted back to a more typical leaf coloring. Interestingly, the leaves still appear somewhat dark when they first emerge, but then they lighten to green.
