What is a perennial that will bloom all summer long?
In general, daylilies are a great perennial addition, but the Stella de Oro’s are some of the earliest and longest blooming varieties. Coneflowers or echinacea have perennial flowers that bloom through summer in pink, purple, white, orange, red, or yellow. Joe-Pye weed, purple coneflower, pale pink Culver’s root, and flowering sedums are all summer-to-fall-blooming perennial powerhouses. Perennials are garden workhorses that save money by returning yearly, but most do not bloom nonstop.
