About Senecio
Dusty Miller (Senecio cineraria) is a cool-season annual in Florida, planted October through May for its striking silver-white, deeply lobed feltlike foliage that contrasts beautifully with colorful companions in borders and containers. It thrives in Zone 9b winters, reaching 6–18 inches tall, and is primarily grown as a foliage accent rather than for its small yellow summer flowers. Starting at $14.95.

Care essentials
Light
Grow dusty miller in full sun to partial sun; it thrives in Florida's bright winter and spring light and tolerates some shade, though foliage is most silvery and compact in full sun.
Water
Water to establish, then water only as needed — dusty miller is drought-tolerant once established. Avoid overwatering; good drainage prevents crown rot. Protect plants on nights with hard freezes.
Soil & Fertilizer
Grows well in sandy, well-drained soils of average fertility. Fertilize lightly at planting with a balanced slow-release fertilizer; excessive nitrogen produces rank, soft growth.
