Also know as Clammy American Birthwort or Shrubby Pennsylvania Birthwort, in 1761 Philadelphia nurseryman John Bartram sent seed to his patron Peter Collinson in London. British taxonomist Dr. John Sims wrote in The Botanical Magazine, 1801, that the vine was soon "adopted for arbors creating "a canopy impenetrable to the rays of the sun, or moderate rain." The flowers provide nectar for the native pipe-vine swallowtail butterflies, and the leaves are an important food source for the caterpillars.Arrives in a 2 quart pot.
