Edelweiss flowers are famous for their fuzzy, star-like appearance. The showier white petals are actually a different form of leaf, while the unassuming yellow centers are the actual flowers. These appear in their second year of growth.
Edelweiss will flower for a few years, but then must be divided to extend the plant’s life. These divisions will then produce more flowers. Deadheading is not necessary, but it can help keep the plant looking neat and clean. Deadheading will prevent the plant from self-seeding.
