Black-Rooted Mullein Overview
Verbascum nigrum is a deciduous or semi-evergreen biennial or short-lived perennial, often dying after it flowers. It has dark green leaves that are hairy and which form in basal clumps out of which slender stalks of warm yellow flowers, with purple stamens at their centres, rise. They flower from late summer to early autumn. Also known as Dark Mullein and Black-Rooted Mullein, Verbascum Nigrum is good for attracting wildlife including birds, bees and other pollinators. Easy to grow from seed, they are particularly suited to gravel - and other dry - garden situations.
