2. Add Annuals to Hanging Baskets, Containers & Window Boxes
One of the easiest ways to add early color to your garden is by planting annuals in hanging baskets, containers, and window boxes. Begin by planting cool-season annuals that will bloom earlier such as calendula, lobelia, larkspur, petunia, oriental poppies, daisies, and viola. Include later-blooming annuals such as snapdragons, hollyhock, delphiniums, nicotiana, geranium, and nasturtium in your planting combinations for a succession of blooms. Plants can be found at local garden centers where annuals should be on display, as well as online through retailers such as Proven Winners and Annie’s Annuals & Perennials (based in Richmond, California).
