Verbascum bombyciferum ‘Arctic Summer’ (silver mullein cultivar) is a biennial, meaning that blooming occurs in the second year after germinating from seed. In its first year, the plant forms a strikingly handsome “rosette” of silvery foliage and makes a lovely feature in the garden.
‘Arctic Summer’ perfectly describes this plant: the powdery white coating of its stems and leaves really does look like a frosting of ice, and its flowers, a sunny yellow, are on display in midsummer.
Look for it in the Flower Garden, near the entrance to the Marco Polo Stufano Conservatory.
