Name this Bush/Tree
We just moved into a house with a bush (maybe it's a tree) that during the winter time looked dreadfully awful. However, now that spring has sprung it has bloomed into beautiful purple blooms making it a gorgeous addition to our gardens. The beautiful blooms are amazing to look at, unfortunately, you have to compete with the enormous amounts of wasps and bees to get a good glimpse. Take a look and let me know if you recognize this.
