Dusty Miller

Jacobaea maritima

flower

Dusty miller is a tender perennial grown as an annual for its striking foliage, which is densely covered in white to gray hairs that give it a silvery, felted look. Plants reach 1.5 to 3 ft tall with deeply lobed, lacy leaves that cool down and unify hot color schemes in beds and containers. It bears small yellow daisy-like flowers, but most gardeners remove them to keep the focus on the foliage. It is highly drought tolerant, deer resistant, and trouble-free.

🌱 Growing Guide

Plant dusty miller in full sun for the best silver color, though it tolerates partial shade, in light, well-drained soil. Once established it is highly drought tolerant and needs little water, and it dislikes soggy ground. Start seed indoors 10 to 15 weeks before the last frost, as it is slow from seed, or buy transplants. Pinch out the flower stalks as they appear to keep plants compact and leafy. In mild zones it may overwinter; elsewhere take stem cuttings under cover or simply replant each spring.

🌼 Have a different variety?Cultivars of the same species usually share the same basic care, and they differ mainly in flower color, height, and bloom form, not in how you grow them. So this guide still applies even if your exact variety isn't the one shown.

🛡️ Pest & disease prevention

Proactive ways to stop trouble before it starts. Tap a name with an arrow for its full guide

Rust
Orange pustules on leaves in wet conditions; water at the base and remove affected foliage
Root rot
Caused by wet, poorly drained soil; plant in light, well-drained ground and water sparingly
Aphids
Occasional on new growth; rinse off and conserve natural enemies

🌸 Blooms & cutting

Dusty miller is grown for foliage, so the main task is removing the flower stalks as they form to keep the plant compact and the leaves vigorous. The silvery sprays are also excellent in fresh and dried arrangements, so cut stems freely, which doubles as shaping the plant.

🥗 Nutrition & benefits

Dusty miller is an ornamental foliage plant, not edible. Its value is silvery, drought-tolerant, deer-resistant foliage that ties color schemes together in beds and containers and lasts well as a cut and dried filler. Have a different variety? Cultivars of the same species share the same basic care, so this guide still applies even if your exact form is not shown.

⚠️ Toxicity & safety

Dusty miller contains pyrrolizidine alkaloids and is considered toxic to cats, dogs, and horses if eaten. It is grown purely for its silver foliage, not for consumption; keep pets from grazing on it.
