The dusty miller plant (Senecio cineraria) is an interesting landscape addition, grown for its silvery-gray foliage. Lacy leaves of the dusty miller plant are attractive companions for many blooms in the garden. Dusty miller care is minimal when the plant is established.
Although the dusty miller flower blooms in mid-summer, the small yellow blooms are small and not considered showy. The foliage of the dusty miller plant, however, 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.
The dusty miller plant is often grown as an annual and discarded after the first season; however, it is an herbaceous perennial and may return in USDA plant hardiness zones 8 to 10. Growing dusty miller can handle the heat, but is best planted where afternoon shade is available during the hottest months of summer.
The dusty miller plant is adaptable to many soil types, thriving in acidic clay to sandy loam soils. The soil must be well-draining to avoid root rot. Water regularly right after planting and withhold water once roots have developed and the plant is growing.
Dusty miller care may involve a midsummer trim if the plant becomes leggy. The dusty miller flower may be removed to keep the plant compact. This specimen can grow as tall as 1 foot (0.5 m.) but often remains shorter. Leave a few flowers to bloom in late summer if you wish the plant to self-seed.
Dusty miller may be used as a background plant for low-growing, creeping annual plants, such as wave petunias. It may be attractively placed among ornamental grasses. Growing dusty miller may effectively be used in borders or as part of an outdoor container planting.
Take advantage of growing dusty miller’s drought tolerance and interplant in a xeric garden, away from the water source. The xeriscape garden is an effective way to save water and time. Include native shrubs and flowers, apply a pre-emergence weed preventer or mulch and forget about dusty miller care for the summer. During periods of extreme drought, however, even xeric gardens benefit from an occasional soaking.
When growing dusty miller, be sure to plant compatible, colorful companions. The lacy leaves are resistant to deer and are an excellent choice for areas where browsing animals may create problems with other plants in the landscape.

Dusty Miller may be grown from seed sown early indoors and transplanted outside after frost, or sown directly in the garden after frost.

Sowing Dusty Miller Directly in the Garden:
Gardeners planting borders and flower beds often choose Dusty Miller (Senecio cineraria) to fill in among brighter annual and perennial flowers. With its unassuming silver and lacy foliage, Dusty Miller complements a variety of different plants and flowers, adding just the right touch to many different landscapes. Dusty Miller grows well in either full or partial sun and is easy to maintain in planting areas because it does not have extensive planting or growing requirements.
Cultivate the growing area with the garden spade prior to planting the Dusty Miller. Work the soil 4-inches deep with the spade and sprinkle the slow-release fertilizer over the soil (consulting the fertilizer package for the recommended amount for the size of the planting area). Smooth the surface of the soil with the rake.
Dig holes for the Dusty Miller with the shovel, spacing the holes approximately 1 to 2 feet apart (depending upon how densely you wish to plant). Make each hole deep enough to place the plants in the soil at the same depth as they are growing in their temporary containers.
Remove each Dusty Miller plant from its temporary container carefully by squeezing the bottom of the container and pulling gently on the central stem of the plant to loosen it.
Place each plant into a prepared hole and fill soil in around the roots. Firm the soil with your hands around the base of each plant.
Provide a thorough watering of the Dusty Miller plants immediately after you finish planting them. Water until the soil is saturated.
Watch the Dusty Miller throughout the growing season and if you notice any blossoms (you will not see many), remove them by pinching them off. Dusty Miller grows best when its energy goes directly to foliage production instead of producing blossoms.
Dusty Miller is drought tolerant so it will not require water unless growing conditions become exceedingly dry. Provide water for these plants only if the soil is very dry and the plants seem to be suffering. Dusty Miller will continue to thrive well into the autumn, even through frosts. Also plant Dusty Miller in containers along with other annual flowers by following the same planting procedure. Provide water daily or every other day for container gardens, however, to ensure the plants do not dry out.
Finally, there are daffodils (Narcissus). These reliable perennials are often the first to bloom every spring. Their cheerful flowers can grow almost anywhere, and their straight and orderly leaves frame the blooms nicely. They'll do well with full sun or partial shade. Daffodils are toxic to deer, so they won't eat them.
If your deer problem is severe, plant these 10 plants in a pseudo-perimeter around the deer-alluring plants in your garden. The strong scent of these "deer deterrents" will disguise the others and leave deer uninterested in pursuing your garden for food.
