Dusty Miller Seeds, Senecio Cineraria | 200 Seeds

Introduction

Dusty Miller (Senecio cineraria, also known as Jacobaea maritima) is a popular ornamental plant prized for its soft, silvery-gray foliage that adds contrast and texture to flower beds, borders, and containers. Grown primarily for its striking leaves rather than its small yellow flowers, Dusty Miller is valued for its heat tolerance, drought resistance, and ability to complement brightly colored annuals. It is commonly grown as an annual in most climates and as a perennial in mild regions.

How to Grow Dusty Miller Seeds

Start Dusty Miller seeds indoors 8–10 weeks before your last frost date, or direct sow outdoors after all danger of frost has passed.

Use a light, well-draining seed-starting mix.

Sow seeds on the soil surface and lightly press them in; do not cover deeply, as seeds require light to germinate.

Mist gently to keep soil evenly moist during germination.

Maintain temperatures between 65–70°F for best germination.

Seeds typically germinate within 10–21 days.

Once seedlings emerge, provide bright light and good air circulation.

Transplant seedlings when they have 2–3 true leaves.

Harden off plants before moving them outdoors.

Space plants 10–12 inches apart in full sun.

How to Care for Dusty Miller Plants

Water regularly during establishment; mature plants are drought tolerant.

Grow plants in well-drained soil; avoid heavy or waterlogged soils.

Do not overfertilize, as excessive nutrients reduce the silvery color of the foliage.

Dusty Miller thrives in full sun and tolerates heat, wind, and coastal conditions.

Remove flower stalks if grown primarily for foliage.

Trim plants lightly to maintain a compact, tidy shape.

Mulch lightly to conserve moisture while allowing good drainage.

Plants are generally resistant to pests and diseases.
