Dusty Miller (Senecio cineraria) is a popular ornamental plant known for its striking, silvery-gray leaves and yellow flowers. While it is often referred to as an annual, its growth habit can vary depending on the climate and region in which it is grown. In areas with mild winters, Dusty Miller can be a short-lived perennial, surviving for several years if protected from frost. However, in regions with harsh winters, it is typically grown as an annual, as it is sensitive to cold temperatures and may not survive the winter months.

Dusty Miller is native to the Mediterranean region and is adapted to grow in areas with warm, dry summers and mild winters. In USDA Hardiness Zones 8-10, it can be grown as a perennial, while in zones 3-7, it is typically grown as an annual. The plant’s hardiness is also influenced by factors such as soil quality, moisture, and exposure to wind and frost. In areas with poor soil or extreme weather conditions, Dusty Miller may not perform well, even if it is grown as a perennial.
Cultivation and Care
