I suspect that this shrub/hedge/tree comes to Arkansas tby way of the nursery. It is a substanital part of the Suburban landscape, and I have seen it raning in forms from small bushes to a small tree.
Distinctive features: Leaves in Spring with a decideley "Fall" color pallette: forest, copper, olive, deep red and purple.
Bold Fragrance. I love it, some folks may call it too strong. It wafts for blocks.
