15 Long-Blooming Perennials to Fill Your Garden with Color (2024)

Perennial plants come back every year on their own, unlike annuals that need to be replaced after the winter. The downside of perennials: a shorter bloom time than annuals. However, you can achieve nearly continuous color with these long-blooming perennials that flower all summer long (and a few even produce flowers from spring into fall).
