Here are some of the flowers blooming in early summer (mid-June through mid-July) in the Pacific Northwest. This is not an exhaustive list, but rather a starting point to help give you some ideas and the flowers I grow on my farm.
Summer is an ideal time for blousy abundance in the garden. This means you have a huge quantity of choice! I love meadow-style summer arrangements with dancing grasses and many small pops of colors. I also love decadent English country garden weddings with roses, foxgloves, and lilies. So much to choose from this time of year!
