Forms clumps of evergreen strappy leaves. Relatively large flowers from early summer, sombre greyish yellow flushed and veined with mauve-purple. Larger than normal seed pods with bright red-orange berries in autumn. The foliage is reputed to be less aromatic than the species.

Moist, well drained soil in sun or shade. Will tolerate poor, dry soil and grow in difficult shady locations where few other plants survive.

Lift and divide clumps in spring. Keep well watered until established. Also from seed.
