The low-maintenance perennials in this design produce a palette of pink, purple, yellow, and white flowers from spring to fall, but shine brightest during the warmest months. And when one variety finishes flowering, another takes its place. Plants with staying power such as yarrow and daylily help bridge any bloom gaps. You’ll even get an encore from the reblooming iris when it produces a second flush of pristine white flowers in late summer after its first show in spring. Site this plan in full sun for maximum blooms.
