About Primula angustifolia Torr.
Primula angustifolia Torr. is a dwarf flowering plant that reaches 1 to 7 cm (0.39 to 2.75 inches) in height. Its leaves are lanceolate to oblanceolate, slightly folded inward, and measure 2–5 cm (0.78 to 1.96 inches) long. This species can grow with a single stem or form clumps. Its flowers have notched petals, and their color ranges from pink to lilac to deep purple, with a characteristic yellow center. Flowers can grow up to 20 mm in diameter, and often appear disproportionately large for this small, diminutive plant. Individuals of this species commonly vary in overall size, number of flowers produced, and flower color. Plants with white flowers are most often found growing in New Mexico. This species blooms from June through August. Its natural distribution covers the Rocky Mountains of Colorado and northern New Mexico. It typically grows above the tree line in tundra habitats, and in rocky locations at elevations above 3000 m (9842 ft). In cultivation, Primula angustifolia is often long-lived, and produces flowers freely, but rarely sets seed. It grows best when grown in containers under glass, planted in a rich sandy growing mix. It has also been grown successfully outdoors in troughs in Scotland.
