Franklinia is a lovely small tree with a fascinating history. Originally discovered in Georgia in 1765 by botanist John Bartram, it disappeared from the wild less than 50 years later. Fortunately, Bartram had collected seeds and propagated plants, so we still have the species today. Franklinia sports lustrous dark green leaves on upright-spreading branches.
One of this tree’s best features is its pure white, golden-stamened, 3-inch-wide flowers that appear in late summer. Often a few late flowers remain when the foliage turns beautiful shades of red and orange in the fall. Though somewhat demanding in its cultural requirements, Franklinia is worth seeking out for its ornamental qualities.
