Pet safety guideAbout 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.

Care essentials
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 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.
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.
