Verbascum 'Polar Summer' often called Giant Silver Mullein, it is a statuesque, architecturally stunning biennial plant famous for its frosted, woolly appearance. In its first year, it forms a massive rosette of broad leaves buried under a dense, silver-white felt coating. In its second summer, it shoots up towering, candelabra-like vertical spires packed with bright, sulfur-yellow saucer blooms. It serves as an unforgettable, drought-tolerant focal accent for gravel gardens, sunny mixed borders, or cottage backdrops. While the individual plant finishes its lifecycle after flowering, it functions as an excellent natural self-seeder so you are guaranteed fresh new plants every year.
