Cloudburst Phlox (Phlox 'Cloudburst')

Cloudburst Phlox (Phlox 'Cloudburst') forms a billowy mound of rich green foliage with upright flowering stems. Abundant deep lavender blooms cover the plant from summer into fall, attracting butterflies and adding soft color to mixed plantings.

Care and garden use

Water regularly and allow enough room to avoid overcrowding. Watch for spider mites in hot, dry weather and foliar nematodes in humid or wet conditions. Cut back foliage after flowering to encourage denser growth and possible rebloom.

Its broad, mounded form makes it a useful flowering accent in mixed borders and naturalized plantings.
