How to Plant, Grow, and Care for Dusty Miller

The dusty miller plant adds beautiful, silvery foliage to a garden and is easy to care for. Learn how to grow it in this in-depth guide.



Dusty miller (Jacobaea maritima), sometimes called silver ragwort, is a member of the Aster family. This plant is an herbaceous perennial that’s winter hardy in zones 7 through 10, although it is very commonly grown as an annual and replaced each year by fresh plants. Here, I’ll share essential tips for growing and caring for this attractive plant.

These plants are native to northern Africa, western Asia, and parts of Europe. They stay fairly compact, rarely reaching more than 1.5 to 2 feet tall, although many cultivars are smaller. 

This species is most commonly grown for its attractive silvery foliage. The leaves are deeply serrated and covered with a downy white fuzz, which gives them a soft, silvery appearance. The flowers are generally yellow and will attract pollinators when in bloom. Some people prefer to remove the flowers to focus on the foliage so the plants maintain a more compact and rounded growth form.

This low-maintenance plant can be grown as an annual or perennial.

This is an easy-to-grow and low-maintenance garden plant. In mild climates, it is also long-lasting and frost-tolerant. In warmer climates, you can grow it as a perennial, although many gardeners still prefer to grow it as an annual.

Regardless of your regional climate, you can take cuttings and overwinter them indoors to be replanted outside in the following spring. You can also start them easily from seeds or find them for sale in nurseries and garden centers. 

Do you plant an annual flower garden? Grow dusty miller along the edge as a border plant or in the middle as a central focal point. Have a patio garden? Grow it in mixed containers with other colorful annuals so their silvery leaves will make a fine companion plant. Need something quick and easy to fill in some gaps in your garden? This is an excellent filler plant that would look great in any setting.


This species is very easy to propagate and grow. Start plants from seed in the spring or start new plants from cuttings taken from mature plants.

Grow from seeds starting 8 to 10 weeks before the last spring frost.

Are you ready to grow dusty miller from seed? It’s quite simple to do. Start seeds indoors 8 to 10 weeks before your average last spring frost date. Do not bury the seeds. Simply sprinkle them on the soil surface and press them onto the soil to make full contact. Then, water the soil well and keep the soil warm and moist until the seeds sprout, possibly up to three weeks after sowing. 

If you use multi-cell pots and have sown multiple seeds per cell, thin them to one seedling per unit. Keep the seedlings warm and the soil moist, and keep them in a location with plenty of bright sunlight or under a grow light. After all the danger of frost has passed and your seedlings are several inches tall, you can safely transplant them into your garden or planter. 


Dusty miller plants, with their silvery leaves, grow vibrantly in a rich, dark soil. Each plant is placed strategically, just inches apart, ensuring they have enough space to spread their foliage.
Purchasing seedlings from a garden center in the springtime is convenient and easy.

Sometimes, it’s just easier to buy seedlings from the store. In the spring, many garden centers selling summer bedding plants will have them in stock.

You will probably have a variety of multi-cell pots full of perky little plants to select from. Choose a healthy-looking batch. Check to see that the stems are straight and strong.

The leaves and stems should be firm and vibrant looking. Don’t buy plants with obvious signs of rot or insect damage.

Propagate plants by taking stem cuttings and rooting them in potting soil.

If you can access a mature plant, you can take cuttings to create more plants. Cut a healthy section of stem tip three or four inches long.

Remove the lower couple of leaves to have a bare stem on one end and a few healthy leaves at the tip end. Dip the bare stem in rooting hormone and then plant the stem in fresh, clean potting soil.

Keep your cutting in a warm, brightly lit location, and keep the soil moist to the touch. After a few weeks, you should start to see fresh leaves growing, and this will be your sign that the cutting was successful.

Plant in the spring after the threat of frost has passed.

When you are ready to plant your seedlings, cuttings, or nursery-grown plants outside, wait until springtime, after the danger of frost has passed. Identify the location where you want to grow your plants.

Dig a hole slightly larger than the plant’s root mass. Carefully remove your plant from its pot and transfer it into the hole. 

Fill in the gaps around the root mass with fresh soil and carefully tamp the soil into place. Now, thoroughly water your plant and keep it moist for the next week to help it settle into its new home.

Growing these plants in cold climates requires protective mulching for winter survival.

You can grow this pretty plant during the warmer months in any climate. In cold climates, cooler than USDA hardiness zone 7, they typically won’t survive the winter.

To increase the odds of your plants surviving the winter when the temperatures drop below zero, mulch your flower beds well to help protect the roots. Plants may be more prone to foliage diseases in very wet, humid climates.

This plant grows well in full sun or partial shade, so it is easy to incorporate into many different landscape situations. You can plant them in the spring and enjoy them all summer and fall.

You can also plant them later in the season to highlight autumn colors and fall-themed cut-flower gardens. They will survive the first few light frosts before dying back for the winter so that you can enjoy them for an extra-long growing season.

Pests and Diseases

This plant is generally not bothered by many pests or diseases. Avoid wet soil conditions that can lead to root rot and fungal diseases like rust. As with any plant, watch for potential insect invasions, such as aphids.

Root Rot

Plants can experience root rot in wet soil, causing the plant to become limp, mushy, and brown.

If plants sit in wet, saturated soil, they can develop root rot. You will notice something is wrong with your plant because it will start to look limp and mushy.

The leaves and stems will become soft and brown, and plants will fall over. Once a plant has developed root rot, it may be best to remove it and avoid overly wet conditions. However, you can try rejuvenating the plant by carefully removing it from its soil, pruning off damaged roots, and replanting it in a fresh, well-draining potting mix.

Rust is a common fungal infection caused by wet weather.

This plant is somewhat prone to rust. Rust is caused by a fungal infection that is most common after an extended period of wet weather. Rust on dusty miller generally looks like yellow or orange patches on the undersides of the leaves and, if allowed to spread, will infect the entire plant, causing it to appear stunted, deformed, or die. 

If you have had problems with rust, try to choose disease-resistant varieties. At the end of the growing season, remove leafy debris from around the plants where diseases can overwinter and spread the following year. Water your plants from below rather than unnecessarily spraying water on the leaves.

These tiny insects damage plants by feeding and transmitting diseases.

Aphids are small, soft-bodied insects, typically green, pink, or grayish in color. They suck hide on the undersides of leaves and along stems, sucking plant juices with tiny piercing mouthparts. Aphids will cause stunted growth and deformed leaves, and they can transmit plant diseases. 

To help control aphids, encourage beneficial insects to visit your garden. Spray heavily infected plants with a jet of water to dislodge and disrupt the aphid feeding cycle.

Spray infected plants with insecticidal soap, but do this in the evenings to minimize potential harmful contact with beneficial insects that fly primarily during the day. Closely follow the directions on whichever product you decide to use.
