Verbascum Seeds - All In One For Home Gardens

Verbascum, commonly known as Mullein, is a hardy flowering plant recognized for its tall upright flower spikes and soft, textured foliage. The plant forms a basal rosette of broad leaves during early growth and later produces vertical stems carrying clusters of small flowers along the spike. Verbascum adapts well to sunny garden areas and tolerates a range of soil conditions, including dry or moderately poor soils. It is commonly grown in borders, cottage gardens, and naturalized landscapes where its vertical structure adds height and seasonal interest.
