Leaves narrowly lanceolate or linear, 1.5–6 cm long, 2–6 mm wide, entire, sessile. Flowers sessile in terminal and upper axillary heads with 5–30 flowers. Sepals 7–10 mm long, lobes lanceolate, acute, more or less equal in fruit, the tube chartaceous in fruit; corolla pink to purplish, 15–30 mm long, tubular in lower ca. two-thirds, lobes spreading, c. 5 mm long, glandular externally; stamens unequally inserted in throat of corolla-tube, at least some shortely exserted from throat of corolla; capsule ellipsoid, c. 5 mm long; seeds 1 per cell. Flowers late spring–summer.

Also naturalised in New South Wales. Native to western North America.

A garden escape collected on a few occasions over 90 years ago from scattered locations throughout the State.

In New South Wales it is an occasional weed of high-montane forests near the Victorian border and could be anticipated in similar situations in this State.
