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.

Plant Addicts Warranty - 1 Year (Extra Purchase Required)
We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die.

The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability).

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
