How to Sow and Plant

Sow seeds in spring or autumn in a well-prepared seedbed.

Broadcast seeds over soil and press lightly — do not bury deeply; mullein seeds need light to germinate.

Keep soil moist until germination (typically 14–28 days).

How to Grow

Provide full sun — mullein performs best in open, sunny sites.

Mullein is tolerant of poor, dry soil once established; avoid heavy, waterlogged sites.

Water moderately during establishment; becomes drought-resistant when mature.

Tips

Sow in drifts/patches for a natural look.

Mullein can self-seed prolifically — deadhead if you want to control its spread.

Use as a vertical accent in wildflower meadows and cottage gardens.

Biennial herb

Great Mullein (Verbascum thapsus) is a tall, biennial flowering herb valued for its dramatic vertical presence and bright yellow blooms. In its first year, it produces a basal rosette of soft, fuzzy leaves; in the second, it sends up tall spires covered in golden flowers that attract bees, butterflies and beneficial insects. Hardy and drought-tolerant, mullein thrives in full sun and well-drained soils, making it a standout choice for borders, wildflower plantings, and naturalised garden areas.
