Our Top Picks For June

June! summer is tantalizingly close and the garden is growing like crazy. June is often a transition period when the late-spring flowers are petering out and the true summer flowers are just beginning to unfurl. Although there are plenty of blooms to be had, don’t forget about spectacular summer foliage for both sun and shade as well. Foliage plants can fill in, stand out, or act as backdrops in the summer garden. Here are a few of our favorite plants – both flowers and foliage – for the month of June.
