Overview
Prosartes smithii (formerly Disporum smithii) is a deciduous perennial reaching 12-24 inches (30-45 cm) tall with a spread of 12-18 inches (30-45 cm), spreading slowly by rhizomes to form loose colonies. The arching, unbranched stems bear alternate, ovate to lanceolate leaves 2-5 inches (5-13 cm) long, medium green with prominent parallel veins, arranged along the upper half of the stem. Pendant, narrowly bell-shaped white to cream flowers 0.5-0.8 inch (13-20 mm) long hang in clusters of 1-5 from the stem tips in April-May. Bright orange to reddish-orange berries follow in late summer—the berries are fleshy, oval, 0.3-0.5 inch (8-13 mm), and persist into autumn. Growth rate is moderate. Hardy to zone 5. A Pacific Northwest native woodland perennial—the arching stems with pendant white bells and bright orange fruits provide three-season interest.
Native Range
Prosartes smithii is native to western North America—from British Columbia south through Washington, Oregon, and California—in moist coniferous and mixed forests, streambanks, and shaded slopes from sea level to 5,000 feet (1,500 m).Suggested Uses
Planted in shade gardens, woodland borders, or native plant gardens at 12-18 inch (30-45 cm) spacing.
