Growing Dusty Miller

Growing Dusty Miller

Silver Dust


Planted for its attractive, silver leaves that set off the colors of other plants. Often used as a border or edging and in mixed containers. Sow outdoors after the last spring frost. Do not cover seed, as light is required for germination. Can start seed indoors 10 to16 weeks before the last frost.


For full sun to partly-shaded locations. Tolerates full shade, especially in warm climates. For well-drained soil, plants dislike soggy soil. Responds well to pruning if plants grow too tall and to remove flowers, which detract from the foliage display.

Use low rates of Algoflash All-Purpose Liquid Fertilizer 6-6-6 (51085), Neptune's Fish & Seaweed Fertilizer 2-3-1 (51221), or Osmocote 14-14-14 (51173).

Alternative Products
