The brilliant scarlet-colored flower of this summer-blooming North American species was considered the finest red in nature upon its introduction to Europe in 1629. Cardinal Flowers grow in moist woodland areas of Monticello, although the seed Thomas Jefferson sowed in a Monticello oval flower bed in 1807 was probably obtained from Philadelphia nurseryman Bernard McMahon. Jefferson-documented: This plant was documented by Thomas Jefferson in his Garden Book, Notes on the State of Virginia, or other writings.
