The Rams Horn Willow, scientifically known as Salix babylonica ‘Crispa’, is a deciduous tree known for its distinct visual appeal. Also called Corkscrew Willow or Dragon’s Claw Willow, its most striking characteristic is the uniquely contorted, twisted branches and leaves that resemble a ram’s horn. This unusual form makes it a compelling focal point, especially during colder months when its branches are most visible.
Distinctive Features and Identification
The Rams Horn Willow is identified by its signature spiraling growth pattern, giving its branches a twisted, contorted appearance. This feature is particularly noticeable in winter after the leaves have fallen, showcasing the tree’s sculptural form. Its narrow, elongated leaves are typically a mid-green color and uniquely curl tightly around the stems, enhancing its “ram’s horn” resemblance.
As it matures, the tree develops rough, furrowed gray bark. Rams Horn Willows are known for their fast growth, potentially reaching up to 30 to 40 feet in height and spread if left unpruned. They generally exhibit an upright growth habit with a spreading canopy.
Ideal Growing Conditions
For the Rams Horn Willow to thrive, full sun exposure is optimal, requiring at least six hours of direct sunlight daily to encourage robust growth and vibrant foliage. While it prefers moist, well-draining soil, this willow adapts to various soil types, including clay, loam, and sand, and is not particularly fussy about soil pH.
Willows prefer ample moisture and tolerate wet soil conditions, making them suitable for planting in areas with consistent moisture or near water features. The Rams Horn Willow is hardy in USDA Zones 4 through 9, demonstrating its ability to withstand a range of temperatures.
Cultivation and Ongoing Care
The Rams Horn Willow requires consistent care. Regular watering ensures the soil remains consistently moist, especially during dry periods and in its younger stages. While it tolerates wet conditions, consistent moisture is more beneficial than periods of drought followed by oversaturation. Fertilization is generally not heavily required, but a light application of a general-purpose, slow-release fertilizer once a year can support healthy growth, particularly for younger trees.
Pruning is important to maintain its shape, manage its size, and enhance the display of its contorted branches. Pruning in early spring, before new growth begins, is recommended for removing dead or crowded branches and shaping the tree. This tree responds well to hard pruning or coppicing, which rejuvenates the plant and encourages more distinctive twisted stems. Rams Horn Willows may occasionally encounter common willow pests such as aphids or diseases like willow blight, which can be managed with appropriate horticultural practices.
Landscaping Applications and Benefits
The Rams Horn Willow is a valued addition to landscapes, primarily used as a striking specimen plant due to its unique form. Its contorted branches provide significant visual interest, especially during the winter months when the tree’s bare structure is fully exposed. This tree is well-suited for planting near water features, such as ponds or streams, where its preference for moist soil can be met naturally.
Its fibrous root system also makes it beneficial for erosion control in wet or riparian areas. The distinctive twisted branches are highly sought after for use in floral arrangements, adding a unique, sculptural element to indoor displays. The tree’s fast growth can provide quick screening or shade in suitable locations.
