It's not currently labelled (many labels were casualties of the move up here), so it's either a true NOID, or it might be one of the 'Griffin Blue' cuttings I rooted from a UGA Open House day a few years back. The foliage is a little greener/less silver than it appears in the photo. I was able to ID all my other butterfly bushes from their flowers, but this and another one haven't been resolved yet. The flowers on both unidentified buddleias are a medium blue/purple, similar to the flower color of Russian sage or catmint.
