Best Plant Partners

Pair annual phlox with other springtime celebrities such as tulips and daffodils. Low-growing phlox forms a tidy mound of color at the feet of lofty spring bulbs, but you can count on phlox to continue blooming long after the flowering bulbs drop their petals. Plant it as a companion for spring flower shrubs: It quickly covers the soil around the shrubs with a splash of color, complementing the blooms overhead. Dwarf fothergilla, azalea, rhododendron, flowering quince, deutzia, and forsythia are some excellent spring shrub companions.

Group three to five plants to create a mass of annual phlox for even more color and texture. Plant drifts of annual phlox along the fronts of borders. Annual phlox can reseed, so it may not be necessary to replant each year.

Annual phlox's rich, vibrant color blossoms always attract attention, blending well with a host of container garden plants. Look for new varieties, such as those in the Gisele series, which are bred to withstand heat and have excellent drought tolerance. These new annual phlox bloom from early spring right through the heat of summer and then unfurl a bold bloom show when temperatures drop in fall.

Annual Phlox Care Must-Knows

Plant annual phlox in full sun and well-drained soil. If the garden bed receives some afternoon shade in the heat of summer, that's a plus. Annual phlox can be started from seed or grown from transplants purchased at a nursery in early spring. Fertilize plants with an all-purpose fertilizer in early summer to encourage several more months of flowering. Cover the soil around plants with a 2-inch-thick layer of mulch to conserve soil moisture.
