Whether you know it as Silver Swirl Centaurea, Dusty Miller, or Centaurea ragusina, this unique ornamental perennial will stand out while adding sparkling color and texture to an outdoor area. The silvery-white color of the leaves is eye-catching, and the wavy edges of the lobed foliage have a ripple-like look, providing texture and dimension. Springtime flowers add more interest, although this plant is primarily grown for the showy foliage.

Silver Swirl Centaurea has a mounded growth habit. Use this plant to create a stunning mass planting, make a natural focal point in a mixed bed or border, or add a filler to a container arrangement. Established plants are easy to maintain and drought tolerant. Foragers like rabbits also leave the unique foliage alone. Grow Silver Swirl Centaurea as a perennial in zones 6 through 9.

Silver Swirl Centaurea Care

Keep the Silver Swirl Centaurea growing and thriving with full sun and dry, well-drained soil. Water only during a dry period because this plant has low water needs. Container-grown plants need water when the soil dries out. This leafy plant is not a heavy feeder, but an annual application of balanced fertilizer helps it start the growing season strong.

This cultivar is more winter hardy than many other varieties and retains its stunning foliage throughout the year. Remove dead or damaged growth as needed. 

Silver Swirl Centaurea Spacing

Silver Swirl Centaurea has a compact growth habit and grows 8 to 11 inches tall and 11 to 14 inches wide. Plant this perennial 13 to 16 inches apart when creating a full mass planting.
