Butterflies...

When we moved into this house the builders had already done some landscaping. One of the bushes they put in next to our garage is now called, 'the butterfly bush!' I really have no idea what it's real name is, but it attracted 100s of butterflies this fall. Our neighbor has the same bush but the blooms are purple. So, you garden/plant people out there....you know what it is, please let me know because I've had alot of people ask me what it is!!! Josh loved going up to it and hitting it and watching all the butterflies fly up...Gidget liked that too actually!! :)
