Summary

Clintonia uniflora, commonly known as Bride’s Bonnet, is a perennial herb native to the moist coniferous and mixed forests of the Pacific Northwest, including regions from Northern California to British Columbia. It is the smallest species in the genus, reaching only 15 to 25 cm (6 to 10 inches) in height. Bride’s Bonnet forms basal rosettes and spreads slowly by underground rhizomes. Each plant typically bears a single, nodding flower, though occasionally an inflorescence of two flowers may occur. The flower features six white tepals, each about 2 cm (0.8 inches) long, and six protruding stamens with yellow, pollen-dusted anthers. After pollination, the flower gives way to a round, blue berry approximately 1 cm (0.4 inches) in diameter, which is attractive to birds and small mammals.

This plant is valued for its delicate appearance and is often used in woodland gardens, shade gardens, and naturalized areas. It requires minimal maintenance once established and is appreciated for its early spring flowers and summer berries. Bride’s Bonnet thrives in part shade to full shade and prefers humus-rich, well-drained soils. It is not drought-tolerant and should be kept moist, especially during the growing season. While generally free from serious pests and diseases, it can suffer from root rot if the soil is too wet. Gardeners should be aware that this plant does not transplant well due to its delicate root system.CC BY-SA 4.0
