Guide to Perennial Flowers by Season

You can have a succession of color from spring to fall by choosing plants with bloom times that overlap with each other. Use these suggestions for sun and shade by season to get started.

Perennials are a must-have in your garden because of their ability to come back year after year, usually growing even stronger and more beautiful with age. But unlike annuals that can bloom non-stop for months, most perennials have a relatively short bloom season, lasting from just a few days to a few weeks. You can still ensure plenty of flowers from your perennials through the seasons by choosing varieties with staggered bloom times. And don’t be afraid to pack in the plants for the best color show: Where three or four types of annuals can brighten a bed all season long, you might need a dozen different perennials to make sure something is blooming from spring to fall. Start planning your continuously blooming garden by selecting a combination of these spring, summer, and fall-blooming perennials for sun and shade.
