Verbascums are eye-catching, drought-tolerant plants with felted, silver-grey rosettes of large leaves. Tall, furry flower-spikes emerge bearing wide-open, (usually) yellow flowers, in early to midsummer. Plants self-seed readily.
The tall, erect spikes of Verbascum 'Blue Lagoon' are packed with small, blue flowers with yellow stamens, throughout summer. It makes a striking show for the middle to back of a multi-coloured border or white bed, and is easily grown from seed.
For best results grow Verbascum 'Blue Lagoon' in well-drained, neutral to alkaline soil in sun or partial shade. Cut old flowering stems to ground level to prolong flowering. Plants are the caterpillar foodplant of the mullein moth, Cucullia verbasci, which causes unsightly holes in the foliage. If possible grow towards the centre of the border, so other plants mask the holey leaves, or grow wild verbascums nearby, onto which you can transfer the caterpillars.
