Notes:

"This is an all-season ornamental with few disease or insect problems. Flowering and fall color are maximized in the sun. Sensitive to pollution, soil compaction, and root disturbance, sourwood is not for urban areas." Ladybird Johnson Wildflower Center. "The bark is dark grayish-brown and fairly deeply furrowed; the tree nearly always has a characteristic lean (toward a former canopy light-gap). The finely serrate, elliptic leaves are distinctive, with the sour taste of garden sorrel..." Weakley 2015
