Get the most from every square inch of your landscape by including long blooming perennials.
Look for plants or varieties of your favorite plants that have the reputation for long bloom and low maintenance.
Walkers Low catmint is a heat and drought tolerant catmint that stays put and blooms all season. A mid-summer trim will improve the growth habit on floppy plants.
Betty Corning clematis has beautiful blue bell shaped flowers that will grace your trellis or arbor for several months in the summer.
Brighten things up at ground level with Rozanne geranium. Not only does this perennial bloom throughout the season, but the foliage also look good all season long.
Blanket flower (Gaillardia) and pincushion (Scabiosa) flowers’ long blooms are great in the garden or used in flower arrangements. They often bloom themselves to death and fail to return after winter. Remove the flowers at the end of the season if this has been a problem for you.
A bit more information: Extend the bloom in your garden with a variety of perennials with different bloom times. Look for and include those with multiple seasons of interest from flowers, foliage, and seedpods. And fill in the voids with annuals that blend nicely with perennials.
