Description

Dodecatheon pulchellum is a herbaceous perennial with single, leafless flower stems, growing from very short erect root stocks with no bulblets. It grows to a height of 5–40 cm (2.0–15.7 in).

Its leaves are basal, 2–15 cm long, blades oblong-lanceolate to oblanceolate, mostly entire to somewhat small-toothed, narrowed gradually to winged stalks nearly as long.

Each plant has between 1 and 25 flowers clustered at the stem top. The calyx is usually purple-flecked, and the five lobes are 3 to 5 millimeters long. The corolla is 10 to 20 millimeters long, the 5 lobes swept backwards, purplish-lavender, seldom white, the short tube yellowish, usually with a purplish wavy line at the base. The filaments are joined into a yellowish tube 1.5–3 mm long, which is smooth or only slightly wrinkled. The 5 anthers are joined to a projecting point, usually yellowish to reddish-purple, 4–7 mm long. The stigma is slightly larger than the style. This plant flowers between April and August.

The fruits are capsules, many-seeded, ovoid-cylindric, hairless to glandular-hairy, membranous to firm-walled, 5–15 mm long, opening from the tip into sharp teeth.

Dodecatheon pulchellum has gained the Royal Horticultural Society’s Award of Garden Merit.[2][3] In cultivation it is hardy down to −15 °C (5 °F), but prefers a sheltered location in partial or full shade with neutral or acid soil, such as a woodland setting.[2]

Native Americans

Dodecatheon pulchellum, pretty shooting star, was used medicinally by the Okanagan-Colville and Blackfoot Indians. An infusion of the roots was used as a wash for sore eyes. A cooled infusion of leaves was used for eye drops. An infusion of leaves was gargled, especially by children, for cankers.
