Harvest Tips
Forever Silver is grown for foliage rather than harvest, but stems can be cut for arrangements throughout the growing season.

Remove yellow flowers to maintain ornamental appearance and redirect energy to foliage production.
Fun Facts
- 🌱 Forever Silver is a cultivar of Senecio cineraria (also called Cineraria maritima), a native of the Mediterranean coast, which explains its excellent drought tolerance and preference for well-draining soil.
- 🌱 The silvery-white color of its leaves comes from a dense covering of fine hairs (trichomes) on the leaf surface, which reflects sunlight and helps the plant conserve water in hot, dry conditions.
- 🌱 In its native Mediterranean habitat, this plant is actually a short-lived perennial, but it thrives as an annual in cooler climates and is often grown as a house plant in winter in northern regions.
