Primula pauciflora, the pretty shooting star, few-flowered shooting star, dark throat shooting star or prairie shooting star, is a species of flowering plant in the primula family Primulaceae. It is a widespread and very variable species, native to western North America, from Subarctic America to Mexico,[1][3] often in xeric (extremely dry) and desert habitats. It is found in the Great Basin Deserts and Mojave Desert. Its synonyms include Dodecatheon pauciflorum and Dodecatheon pulchellum.[1][2]
Description
Primula pauciflora is a widespread and highly variable polyploid complex (2n = 44, 88 and 132). The species is generally hairless, with a flowering stem 10–40 cm (4–16 in) tall. The inflorescence is made up of between 2 and fifteen flowers. The flower generally has 9–14 mm (0.4–0.6 in) long petals, magenta to lavender in color.[2]
Primula pauciflora has been divided into up to seven varieties each with their own often complex set of
Varieties
As of April 2022[update], Plants of the World Online accepted seven varieties (distributions from the same source):[1]
- Primula pauciflora var. cusickii (Greene) A.R.Mast & Reveal – British Columbia, Idaho, Montana, Oregon, Washington State, Wyoming
- Primula pauciflora var. distola (Reveal) A.R.Mast & Reveal – South Dakota, Wyoming
- Primula pauciflora var. macrocarpa (A.Gray) A.R.Mast & Reveal – Alaska, British Columbia, California, Oregon, Washington State
- Primula pauciflora var. monantha (Greene) A.R.Mast & Reveal – California, Oregon, Utah, Washington State
- Primula pauciflora var. pauciflora – widespread from subarctic America to Mexico
- Primula pauciflora var. shoshonensis (A.Nelson) A.R.Mast & Reveal – California, Idaho, Nevada, Oregon, Utah
- Primula pauciflora var. zionensis (Eastw.) A.R.Mast & Reveal – Arizona, Colorado, Utah
Cultivation
Under the name Dodecatheon pulchellum, the plant has gained the Royal Horticultural Society's Award of Garden Merit.[4][5] If not provided adequate moisture in the growing season they will die back to the roots, but will return in the next year.[6] 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.[4] Though they need moisture, the pretty shooting-star also requires good drainage, not a boggy or riparian situation. When grown in good conditions the crown will become much larger with multiple blooming stems. Larger plants can be successfully divided for propagation in the late fall.[6]
