This is an azalea left over from some that my great grandmother planted sometime in the late 1940's or maybe 1950's. All of the others are definately 'Formosa', however this one is a light lilac color. It has a slightly more lavender tint than 'George Tabor'. Anyone have an idea what it may be? When I Google "lavender azalea" all I come with is G.Tabor or Encore types.

Many of the originals have died from what I believe to be root rot from some oak stumps. I managed to air layer this one and plant it in another area.
