White willow Salix alba
ABOUT
Salix alba, commonly known as the white willow, is a type of flowering plant that is often recognized for its elegant and distinctive appearance. It typically displays a spreading canopy that is formed by multiple branches, which adds to its aesthetic appeal. The plant bears narrow, elongated leaves, which are green on the upper side and possess a pale, almost silver-white hue on the underside, giving the species its common name. These leaves are finely toothed along the edges and have a somewhat delicate and fragile appearance. The bark of the white willow is another characteristic feature. It is generally rough and furrowed, displaying a grayish color that can sometimes look whitewashed, contributing to the 'white' aspect of its common name. During the blooming season, the white willow produces catkins, which are cylindrical flower clusters that dangle from the branches. These catkins are often yellowish or silvery and can add a subtle decorative effect to the plant. Throughout the seasons, the white willow's appearance can change. In the spring, the fresh leaves and catkins provide a vibrant look, while in the fall, the leaves may turn yellow before they drop, reflecting the seasonal cycle. The overall impression of the white willow is one of grace and poise, with its cascading branches, striking foliage, and classic bark texture, making it a noticeable plant in any landscape where it grows.

ToxicityTo humans
White willow is not typically considered toxic to humans. It has been used historically for its salicin content, which is a precursor to aspirin, and it is generally considered safe when used in moderation as a natural remedy. However, consuming large amounts of white willow bark might lead to similar side effects as aspirin, such as stomach upset, ulcers, or allergic reactions in people sensitive to aspirin.
To pets
White willow is generally considered to have low toxicity to pets. However, as it contains salicin like aspirin, excessive ingestion may potentially cause similar side effects in pets as in humans, such as gastrointestinal upset or even more serious conditions like ulcers or kidney issues if consumed in large amounts. Monitoring of pets that have ingested white willow is advisable, and a veterinarian should be consulted if adverse reactions are suspected.

WaterThe White Willow (Salix alba) prefers consistently moist soil and should be watered deeply, especially during dry periods. On average, watering once a week with around 1 to 1.5 gallons of water should suffice, but this may increase to twice a week in periods of extreme heat or drought. Ensure that the planting area allows for proper drainage as the White Willow does not tolerate waterlogged conditions. Adjustments in watering frequency should be made according to rainfall and season, with less water required during the dormant winter months.
LightThe White Willow thrives best in full sun to partial shade. A spot that receives at least 6 hours of direct sunlight per day is ideal for this plant. Avoid deeply shaded areas as this can impact the tree's growth and overall health.
TemperatureWhite Willow is quite adaptable to temperature fluctuations and can survive in a temperature range from about -30 to 100 degrees Fahrenheit. However, the ideal growing conditions for the White Willow are within 50 to 75 degrees Fahrenheit where it can thrive outside any risk of frost damage or heat stress.
PruningPruning the White Willow is generally done to remove dead or damaged branches, to shape the tree, or to control its size. The best time for pruning is late winter or early spring before new growth starts. Pruning can be done annually or as needed to maintain the desired tree form and health.

Life cycleThe common name for Salix alba is White Willow. The life cycle of this plant begins with seed dispersal, typically taking place in spring, where its numerous tiny seeds spread by wind or water. These seeds germinate rapidly in moist soil conditions, initiating the seedling stage where the plant begins to grow its characteristic lance-shaped leaves and flexible stems. The White Willow then enters a vegetative stage, growing rapidly and reaching maturity within a few years, with its sex being determined since willows are dioecious, meaning individuals are either male or female. The mature willow produces flowers in catkins, which, depending on the sex, either produce pollen or develop into seed-bearing capsules after pollination. After years of growth, this perennial can live for several decades, constantly growing and reproducing annually, with the ability to also propagate vegetatively from cuttings or broken branches, which readily form roots in moist soils.
PropogationPropogation time
Early spring
The White Willow, known scientifically as Salix alba, is most commonly propagated through cuttings. This method is popular because it is simple and effective. The best time to take cuttings for propagation is in late winter or early spring, just before the willow begins active growth. A cutting should be about 9 to 10 inches long (23 to 25 centimeters) and contain several buds. The cutting is then planted directly in moist soil or sometimes in water, where it will quickly develop roots. It's important to keep the soil or water moist until the cuttings have rooted well, which can take a few weeks. Once rooting has occurred, the young saplings can be transplanted to their final location.
