Salix myricoides Muhl. var. rigida (Muhl.) Dippel: Description, Origin, and Common Names
Salix myricoides Muhl. var. rigida (Muhl.) Dippel is a species of willow native to North America, specifically found in the eastern and central United States, ranging from the Great Lakes to the Gulf Coast. Commonly known as gray willow, this plant also goes by the names stiff willow, leatherleaf willow, and bay-leaved willow.
The grey willow is a deciduous shrub or a small tree that can grow up to 6 meters in height. It grows in a multi-stemmed form and has a rounded, open crown. The leaves of the plant are long and narrow, resembling the leaves of myrtle, thus the species is called myricoides. The leaves are dark green, stiff, glossy, and have a leather-like texture, which gives the plant its name "leatherleaf."
Salix myricoides Muhl. var. rigida: Uses
This species of willow has been used for various purposes by humans for centuries. Native American tribes used gray willow bark to treat different illnesses, including fever, colds, and coughs. They also brewed a tea from the leaves that helped to relieve pain and inflammation. The bark and wood were used by pioneers for basketry, fencing, and fuel.
Today, gray willow is still used in traditional medicine, but it is also grown as an ornamental plant in gardens and parks. It attracts a variety of birds, butterflies, and other insects and is often used in landscaping for erosion control, stream bank stabilization, and habitat restoration.
Salix myricoides Muhl. var. rigida: General Appearance

Light Requirements
Salix myricoides Muhl. var. rigida (Muhl.) Dippel commonly known as Stiff Willow, thrives in full sunlight to partial shade conditions. A moderate amount of sunlight is ideal for its growth. In low light conditions, the plant may survive, but its growth may be stunted, and its vitality may be compromised.
Temperature Requirements
The typical growth range for Salix myricoides Muhl. var. rigida (Muhl.) Dippel is between 10 to 30 degrees Celsius. The plant can withstand freezing temperatures during the winter months and within the range of -34 to 43 degrees Celsius, but prolonged extreme temperatures may result in the plant's death. Additionally, the plant is sensitive to extreme heat, and subsequently, it requires adequate access to water during hot and dry weather conditions.
Soil Requirements
Salix myricoides Muhl. var. rigida (Muhl.) Dippel thrives in fertile, well-drained soils. The plant can tolerate a range of soil types, including sandy, loam, and clay soils. It requires neutral to acidic soils, and a pH range of 5 to 7 is ideal for its growth. Furthermore, the plant is sensitive to waterlogging, and consequently, it requires soil with efficient drainage.
Cultivation Method
Salix myricoides Muhl. var. rigida (Muhl.) Dippel, also known as red willow, is a hardy deciduous shrub that thrives in moist soils and full sun. The plant prefers to grow in areas with morning sun and some afternoon shade, as too much sun can lead to leaf scorching.
Red willow shrubs are easy to propagate by rooting stem cuttings taken in late winter or early spring. The plant prefers well-drained soils, but it can tolerate standing water for short periods.
Watering Needs
Red willow shrubs need regular watering, especially during the first few years of growth, to establish deep roots. The plant thrives in moist soils, but it can tolerate short periods of drought once it matures.
It is imperative to watch the soil moisture levels in warmer climates, especially during the summer months. Remember to water sufficiently without drenching the plant.
Fertilization
Red Willow shrubs do not require much fertilization. However, as with any plant, a food source will assist the plant in producing a good number of blooms and ensuring steady growth. This plant will benefit from a slow-release fertilizer application during the spring dormant period.
Over-fertilizing the plant can lead to excessive growth and weak branches, making the plant more susceptible to damages from wind and snow.
Pruning
Red willow shrubs require little to no pruning, although a gentle prune during late winter or early spring every few years can help stimulate new growth and form a denser appearance. It is important not to overly prune the plant, as the red willow shrubs produce few side shoots.
To prevent the plant from developing diseased and weak wood, remove any dead or dying branches and those rubbing against each other, particularly those that form low on branches or in older, mature shrubs. Red Willow shrubs produce a lot of strong wood that can withstand harsh weather conditions.
Propagation of Salix myricoides Muhl. var. rigida (Muhl.) Dippel
Salix myricoides Muhl. var. rigida (Muhl.) Dippel, commonly known as the sandbar willow, can be propagated through several methods. It is a versatile plant that can be grown from seeds, hardwood cuttings, and even root cuttings. Here are some propagation methods:
Propagation through seeds
Propagation through seeds is the most common method of growing Salix myricoides. The seeds should be collected in late summer or early fall when they are fully ripe. After collecting, the seeds should be kept in a cold, dry place, and sown in the spring. Sow the seeds in a well-draining soil mix and keep them moist until germination. The seedlings can be transplanted to their permanent location once they are large enough to handle.
Propagation through hardwood cuttings
Propagation through hardwood cuttings is another easy and efficient method of growing Salix myricoides. The cuttings should be taken during winter when the plant is dormant. Select a healthy stem and make a clean, slanted cut, about 8-10 inches long. Dip the cuttings in rooting hormone and plant them in well-draining soil mix, burying 2/3 of the cutting. Keep the soil moist and make sure to place the pot in a shaded location for the first few weeks. After a month or two, the plant should start showing roots, and it can be transplanted to a larger container or into the ground.
Propagation through root cuttings
Propagation through root cuttings is a more challenging method but can be a good option if you want to create more plants. To propagate through root cuttings, dig up the plant in winter when it is dormant. Select a healthy root and cut it into 2-3 inch sections. The root cuttings should be placed in a well-draining soil mix, burying 2/3 of the cutting. Keep the soil moist and warm, and the cuttings should start showing signs of growth in a few weeks. Once they are growing strong, the cuttings can be transplanted to a permanent location.
Disease Management for Salix Myricoides Muhl. Var. Rigida (Muhl.) Dippel
Salix Myricoides Muhl. Var. Rigida (Muhl.) Dippel is relatively resistant to most diseases, but the following diseases can pose a threat to the plant:
Cytospora Canker
Cytospora canker is a fungal disease that affects the bark of the plant, causing it to crack and split. Infected branches usually wilt and die. To manage cytospora canker, prune the affected branches at least 6 inches below the infected area. Dispose of the pruned branches and disinfect the pruning equipment.
Powdery Mildew
Powdery mildew is a fungal disease that affects the leaves, stems, and flowers of the plant. Symptoms of powdery mildew include the appearance of a white, powdery substance on the plant's surface. To manage powdery mildew, remove and dispose of infected leaves, avoid overwatering, and provide adequate air circulation.
Leaf Spot
Leaf spot is a fungal or bacterial disease that affects the leaves of the plant, causing the leaves to develop small, circular spots. These spots can merge and cause the leaves to fall off. To manage leaf spot, prune the affected branches at least 6 inches below the infected area, water the plant at the base, and avoid wetting the foliage.
Pest Management for Salix Myricoides Muhl. Var. Rigida (Muhl.) Dippel
Salix Myricoides Muhl. Var. Rigida (Muhl.) Dippel is also relatively resistant to most pests, but the following insects can pose a threat to the plant:
Aphids
Aphids are small, soft-bodied insects that suck the sap from the plant's leaves and stems. Symptoms of aphid infestation include distorted foliage and the appearance of a sticky substance on the plant's surface. To manage aphids, spray the plant with a strong jet of water, use insecticidal soap or neem oil, or introduce natural predators such as ladybugs or lacewings.
Willow Leaf Beetle
The willow leaf beetle is a beetle that feeds on the leaves of the plant, causing defoliation. Symptoms of willow leaf beetle infestation include irregular holes on the plant's leaves and skeletonized foliage. To manage willow leaf beetle, introduce natural predators such as birds or parasitoid wasps, manually remove the beetles and their larvae, or use insecticides if necessary.
