Answer: In my experience, rather than reflecting soil conditions, the fall coloring of burning bush (Euonymous alatus) is most pronounced in full sun situations. Partial shade can reduce it to a pink cast rather than that fiery red. Color can also be affected somewhat by drought. Also, there can be some color variation from plant to plant if they were grown from seed rather than from cuttings taken from plants selected on the basis of superior fall color.
