How to Grow Dusty Miller


Yes, Dusty Miller produces flowers. But, most home gardeners grow them for their fern-like, silvery foliage. They are a strikingly attractive plant in the flowerbed, and perfect for border edging. Dusty Miller plants, are an easy to grow perennial. However, some people grow them as annuals.

If you are space limited, you can grow them in containers on your patio or deck. Mix them in with other annuals or perennials to make an attractive, colorful arrangement.

Plant Propagation:

Dusty Miller plants are grown from seed. Directly seed them into your garden 2-3 weeks before the last frost in your are. For an early start, sow Dusty Miller seeds indoors in seed trays or pots, 6-8 weeks before the last frost. Seeds take about 2-3 weeks to sprout. Keep the soil moist during the germination period. If starting indoors, we recommend using a heated germination mat.

When sowing seeds, cover lightly with a loose soil. Final spacing for the plants is 10"-12" apart. They tolerate a little crowding.

Note: In warm winter areas, seeds can be started in the fall.

How to Grow Dusty Miller:

Grow Dusty Miller in full sun to partial shade. They grow well in rich, well drained soil, but will tolerate average soil. Mix in compost and manure prior to planting, If growing as a perennial, select a location where they can grow undisturbed for years. Dusty Miller can be grown as annuals, too.

Allow the soil to dry between watering. Once the top couple inches of soil is dry, water thoroughly. Add a general purpose fertilizer once or twice a month, especially in poor soils. Mulching around plants will help keep weeds down, make an attractive appearance, and provide nutrients to the plants.

Dusty Miller grow tall, 10" - 18" tall. They will produce flowers. Many people remove them, or pinch back the buds to promote leaf growth. Trim plants as desired, to maintain an attractive shape.

Insect and Disease:

Dusty Miller are resistant to insects and disease. Apply insecticides or fungicides only as needed.
