Summary

Streptopus amplexifolius, commonly known as Claspleaf Twistedstalk, is a deciduous perennial herb native to cool, moist, temperate forests and streambanks in Northern Europe, the Northern Pacific, and Alaska. It typically grows to a height of 40–100 cm with a creeping habit, featuring alternate, oblong-lanceolate leaves that clasp the stem and are 5–14 cm long. The plant produces small, bell-shaped, greenish-white flowers in late spring to early summer, which are followed by red berries that are somewhat showy and can attract birds. The flowers are not particularly conspicuous but add a delicate charm to shaded garden areas.

Claspleaf Twistedstalk is valued for its naturalistic appearance and ability to thrive in shady, moist environments, making it suitable for woodland gardens, shade gardens, and naturalized areas. It is also used for ground cover and along streambanks or water features in cultivated landscapes. It prefers consistently moist, humus-rich soil and can tolerate a range of light conditions from full shade to filtered sunlight. While it is not prone to serious diseases or pests, it can be sensitive to drought and may require additional watering during dry periods. Gardeners should note that it can spread to form colonies and may need to be managed to prevent unwanted naturalization.CC BY-SA 4.0
