Most summer perennials (and annuals, for that matter) start to fade away once their blooming time is over. However, every blossom has its season, so perking up your garden’s color is simply a matter of choosing the right plants and adding them at the right time.
Buy them already blooming: The quickest way to add late summer color to your garden is to buy late summer bloomers in pots, dig holes where you want them, and drop them in pot and all. You can easily relocate them to other garden areas as the season progresses.
Wait for them to begin to die back, then dig up the pots and plant the plants directly in the ground and enjoy their color again this time next summer.
Deadhead and prune: Deadhead early summer bloomers to keep them flowering. As soon as early-bloomers pass their peak, cuts them back nearly to the ground and see if you can coax them into producing a second crop of flowers.
Rely on herbs: Lavender, sage, bee balm and hyssop are just a few of the herbs with gorgeous, colorful flowers. Once established, herbs are generally not much work, so they offer a lot of bang for the buck.
Reduce height: Some of the best plants for late-summer color, tend to flop over just when they’re about to bloom. To avoid this, cut back the stems by a third when the plants are about half their expected height. They will bloom later but be sturdier and shorter.
Think outside the box: Instead of settling for the same old, same old, try out a few new varieties for late summer color, perhaps decorative artichoke, tobacco plant, sea holly shrubby, cinquefoil and other plants that flourish in Mediterranean regions.
