Dusty Miller

Jacobaea maritima (jay-koh-BEE-uh mar-ih-TY-muh)

Family: Asteraceae Non-native Herbaceous (3-15 ft)

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 under glass but most people just replant with new plants in the spring. This plant is sometimes offered as a florist plant. Insects, Diseases, and Other Plant Problems: No significant problems. Susceptible to rust.
