Phlox × 'Cloudburst' brings bold summer color with an upright, well-filled habit that looks great from early season through bloom. You get a sturdy, mounded perennial that reaches about 26-28 inches tall and spreads to roughly 38-42 inches at maturity, making it an easy fit for mixed borders and large containers.
Plant it where it will receive full sun to part shade. In hotter climates, a little afternoon shade can help keep the display going. Give it average, well-drained soil and water regularly during establishment; once settled, consistent moisture supports the longest, most continuous flowering. Mulching helps keep roots cooler and reduces moisture swings.
Cloudburst produces showy lavender-purple flowers with a bright eye and is a strong choice when you want a classic phlox look in a taller, cushion-forming plant. The blooms are attractive to pollinators and also make colorful cut stems. Deadheading spent clusters can encourage additional flowering and keeps the plant looking tidy. For best overall health, allow good air circulation and avoid overhead watering when possible.
Use this phlox to add midsummer impact in borders, cottage-style plantings, and sunny foundation beds. It pairs well with other sun-loving perennials and ornamental grasses, and its height helps it read clearly from a distance without needing staking.
