Easily grown in average, dry to medium, well-drained soil in full sun. Tolerates a wide range of soil conditions including poor dry soils, but must have good drainage.

Verbascum chaixii is a narrow-leaved mullein species that is sometimes commonly called nettle-leaved mullein. It is a somewhat short-lived perennial which forms a large basal rosette (8-12" wide) of woolly, coarsely toothed, dull grayish-green, ovate-oblong leaves (3-6" long) from which rise spire-like, unbranched stems (2-3" tall) with terminal racemes of 5 lobed, nearly flat, yellow flowers (1 inch diameter) with purplish stamens. Blooms in late spring to early summer.
Genus name may come from the Latin word barbascum which means bearded plant.
No serious insect or disease problems. Susceptible to spider mites in hot conditions. Plants grown in rich, fertile soils grow taller and may need staking or other support. Wet, poorly drained soils are usually fatal.
Borders and cottage gardens. Good vertical accent. Grows well in poor soils and will grow well on dry, rocky slopes or scree.
