In 1809 Jefferson wrote to Judge William Fleming, a lifelong friend in Richmond, and and thanked him for sending the foliage of the "Alleghany Martagon . . . A plant of so much beauty & fragrance will be a valuable addition to our flower gardens. Should you find your roots of it I shall be very thankful to participate of them, & and will carefully return you a new stock should my part succeed & yours fail." Jefferson also ordered this tall and stately native lily with its reddish-orange flowers from McMahon in 1812.
