Native Plant Alternatives to Verbascum thapsus (Great Mullein)

How Great Mullein Invades Wild Spaces (and What to Grow Instead)

Great mullein (Verbascum thapsus) is more than just a fuzzy-leaved wildflower—it’s an opportunist that has made itself at home across much of North America. Native to Europe, northern Africa, and Asia, it was introduced to the U.S. in the 18th century and now pops up in fields, roadsides, pastures, and freshly disturbed ground. It is listed in the Invasive Plant Atlas of the United States.

What makes this plant so formidable? Great mullein thrives in poor, dry soils where others struggle. Each flowering spike produces hundreds of thousands of seeds that can wait dormant for years, then sprout when the ground is disturbed. With this tenacity, it rapidly colonizes after fire, tilling, or construction—competing with native grasses and wildflowers for sunlight, space, and nutrients. While it doesn’t always form dense monocultures, in disturbed open sites it can slow native seedling recovery and shift plant composition if left unchecked.

Its impact reaches further near working landscapes: great mullein can host the mullein bug (Campylomma verbasci), an orchard pest in some regions. Its flowers are visited by generalist pollinators, but native forbs typically provide richer habitat, so limiting spread in natural areas remains the goal.

At-a-Glance ID

• Year 1: silvery, woolly basal rosette (often to ~30 in wide).
• Year 2: single, unbranched flower spike ~5–8 ft with five-petaled blooms (typically yellow).
• Prefers full sun, dry/disturbed soils; deep taproot.

Wildlife-Friendly Alternatives

Swap mullein for drought-tough natives that feed pollinators and knit soils: Echinacea purpurea, Solidago spp., Asclepias tuberosa, Verbena hastata, or grasses like Schizachyrium scoparium. You’ll get nectar, seed, and structure—without the reseeding risk.
