Salix irrorata, commonly known as Dewystem Willow, is a deciduous shrub native to riparian zones, wetlands, and moist open woodlands in the Southwestern United States. It typically grows to a height of 6-10 feet (1.8-3 meters) and a width of 10-15 feet (3-4.6 meters). The Dewystem Willow has a bushy habit and is noted for its attractive, bluish-white stems that become more pronounced in winter, providing year-round interest. Its leaves are narrow and elongated, and it produces catkins that are not particularly showy but add a subtle charm in early spring.

The Dewystem Willow is valued for its ability to thrive in wet conditions and its ease of maintenance. It is often used for naturalistic plantings, erosion control, and as a wildlife habitat, offering food and shelter for various species. Regular coppicing is recommended to maintain its size and to enhance the stem coloration, which is most vibrant on new growth. This shrub is best suited for full sun to part shade and requires abundant water, reflecting its natural preference for moist environments. It is adaptable to a range of soil types, provided they are well-draining. While it has received the Royal Horticultural Society’s Award of Garden Merit, gardeners should be aware that willows can be susceptible to pests like aphids and diseases such as willow scab and black canker.CC BY-SA 4.0
