Summertime Blooms

The former owners of this rental did a wonderful job of landscaping.  We have flowers blooming all over.  We've added to the mixture by placing hanging pots hoping to attract  humingbirds and by planting a few flowers in our vegetable garden.  So far, we've only seen one humingbird - I think they come around when we're not watching.

Anyone know what the name of the lavender flower is?  It is beautiful!
