Description

Dusty Miller is usually grown as an annual for its silvery wooly leaves to provide contrast in the garden or a container. It prefers light, well-drained soil in sun or shade and is drought tolerant. Remove the blooms to help promote foliage growth. 

A popular plant found in interiorscapes, forests or natural areas, patios, or in garden beds and borders.  Silvery wooly leaves provide excellent contrast in beds.  Start seeds indoors 10-15 weeks before the last frost date or purchase plants as starters in 6-packs.  You can take stem cuttings to overwinter but most people just replant with new plants in the spring.

Insects, Diseases, and Other Plant Problems:  No significant problems.  Susceptible to rust.
