Vanillaleaf (Carphephorus odoratissimus) is a perennial that produces many small purple flowers in terminal, flat-topped inflorescences. Its basal leaves are straplike, are 6 inches to 1 foot in length, and form a rosette. Stem leaves are clasping and reduced in size as they ascend the stem. They are alternately arranged. Stems are glabrous.

The common name, vanillaleaf, refers to the vanilla-like scent that the wilting leaves emit when crushed. The species epithet, odoratissimus, is from the Latin for “most fragrant” and also alludes to the leaves’ scent.

Vanillaleaf occurs naturally in mesic to hydric pine flatwoods, moist sandhills and bogs and blooms late summer into fall. It is found throughout Florida; however, the species has been divided into two varieties with distinct ranges: C. odoratissimus is found in the Panhandle and north and central peninsula. C. odoratissimus var. subtropicanus (sometimes known simply as C. subtropicanus) is endemic to the central and southern peninsula. Their ranges overlap in Citrus, Sumter, Orange and Osceola counties. The leaves of C. odoratissimus var. subtropicanus emit little to no vanilla-like scent. Its common name is false vanillaleaf. Both varieties attract butterflies and other pollinators.
