Thanks, Cheryl! This particular bush has to be 15 years old, making it a pretty mature specimen. We're guessing it was planted shortly after the original owners moved in when the house was built in 2005.
When we moved in, this island was choked out with stuff. In front of this butterfly bush was a massive forsythia bush, had to be 8 feet wide - I've never seen one so large. It was half dead and blocking light, so we removed it. There was also a tree stump, a couple of other half dead/choked out bushes that we removed/dug up. The butterfly bush has thrived and branched out. We planted the Susans; one of my faves.
I'm guessing it was a wee shrub when it was planted. The original homeowner just overplanted around it - easy to do when it's all so small. If you plant one, just make sure it can grow out all around about 5-6 feet, as it will get there eventually! Hummingbirds, bees, and of course butterflies, all love this thing.
I prefer looking for dwarf versions of just about everything.
