Foliage of the dusty miller plant is long lasting and drought resistant. As with most silvery, furry plants, growing dusty miller helps the garden remain attractive through the heat of the summer. It will also tolerate frost. Dusty miller prefers to be grown in full sun but will tolerate part shade. In more shade, the silver look of the leaves will be less intense and the plants will look greener. Dusty miller also likes well-drained soils. In too heavy or too wet of soil, there is a much higher risk that root rot will develop.
