Choose Plants with Different Bloom Times

Combine early, mid-, and late-season bloomers to enjoy continuous color throughout autumn. Pair flowers like dahlias, asters, chrysanthemums, and pansies to keep your garden vibrant as the seasons change.

Layer Plants for More Visual Interest

Create depth by placing taller plants such as sunflowers, gladiolus, and Russian sage at the back of borders, medium-height flowers in the middle, and compact varieties like pansies or marigolds along the front.

Add Texture with Foliage and Ornamental Grasses

Mix flowering plants with ornamental grasses, colorful foliage, or evergreen shrubs to create a landscape that remains attractive even after some blooms begin to fade.
