Flowers that bloom in July are tough, able to stand up to the hot sun of mid-summer. Gardeners pick from plants that thrive in full sun as well as plants that prefer more shade. The plants take over when the late spring and early summer flowers are ending, keeping the garden alive and bright until the fall blooming flowers are ready to kick in.
