When I think of summer, I think of lavender - purple, blue, white, even pink lavender. We are fortunate here in Sonoma County to live in a Mediterranean climate and therefore can grow a wide range of lavender.
There are several lavender gardens and farms nearby. The newest addition is Bees N Blooms which features a lavender labyrinth that I still have to write about. My favorite place over the years has been the lavender garden of Matanzas Creek Winery that I wrote about here and here. It is still my go-to place if I want to experience the beautiful sight and the wonderful scent of lavender.
