Mullein Seeds - Herbal Plant for Home Gardens

Mullein, botanically known as Verbascum thapsus, is a biennial plant valued for its tall flowering spike and soft, velvety foliage. It develops a basal rosette of broad leaves in the first year and produces a tall central stem with clusters of small yellow flowers in the second year. This plant adapts well to a wide range of climates and performs best in full sun with well-drained soil. Mullein is commonly used in naturalized planting, wildflower gardens, and open landscapes, where it establishes easily from seeds and tolerates dry, poor soils once mature.
