Deertongue (Carphephorus spp.)
This plant is named because the leaves are shaped like a deer's tongue - long and narrow, with a reddish-purple streak at the base. It is most commonly found in damp, pine flatwoods, which are kept open by regular fires. The plant is sometimes called vanilla leaf, or wild vanilla, because of the distinct smell of vanilla when the leaves are crushed. The leaves contain crystals of a chemical called coumarin, which gives off the vanilla-like odor.
In the 1900's, the leaves were collected and sold to flavor pipe and cigarette tobacco, however, modern processes use artificial additives to enhance tobacco flavor, so deer tongue is no longer collected commercially for this purpose.
Deertongue does not grow well on high, dry land or in swampy, wet areas but prefers damp pine flatwoods that have been kept open with prescribed fire. It is common throughout North America.
