Sourwood (Oxydendrum arboreum)

Oxydendrum is an underused plant, to say the least. This is a small to medium tree which is suitable for large planters or small gardens. The drooping fragrant flower panicles in the summer veil the tree in white and the flowers persist after the foliage turns in the fall; the scarlet fall color is unsurpassed. The tree is listed as zone 5 but there is one flowering in Maine.
