Add summer color plants to your landscape, which may include lantana, firebush, Poinciana, esparanza, firespike, caladium, coleus, cocktail begonia, moss rose, hibiscus, bougainvillea, purslane, cannas, verbenea and durantas. Use liberal amounts of compost and mulch at planting.

Seeds that may be sown directly in the warm soil include amaranthus, celosia, morning glory, sunflowers and zinnias.
