10 Robust Summer Blooming Perennials

Right about July the garden is bursting at the seams with loads of flowers and lush growth, but it’s also the time when many plants are pretty needy. Feed me. Water me. Weed me. Mulch me. On it goes. How about a few that just do their thing without much input from you. Sound good? Here are a group arranged by mature size, so you can layer them into existing plantings or start from scratch.
