Yezo Alpina Willow Salix nakamurana var. yezoalpina

ABOUT
The plant in question, commonly known as the Yezo alpine willow, is characterized by its flexible branches which often bear a profusion of narrow leaves. These leaves tend to be green with a slightly blueish tint, perhaps due to a fine layer of hairs that can give them a silvery appearance. The shape of the leaves is generally elongated, often with a pointed tip. During the blooming period, the Yezo alpine willow produces flowers which are structured in what are called catkins; these are slim, cylindrical flower clusters. Each catkin is composed of numerous small flowers without significant petals, which is typical for willow species. The flowers can vary from green to yellowish tones and are often accompanied by fluffy white seeds that can be seen floating in the air once mature. The bark of this plant is another distinctive feature, typically presenting a rough texture and a color palette that ranges from grey to brown shades. The overall aesthetic of the Yezo alpine willow is one that is quite rugged and robust, often exuding a wild beauty that resonates well with the alpine environments where it is commonly found.

Toxicity
To humans
There is limited specific information available about the toxicity of Salix nakamurana var. yezoalpina, more commonly known as "dwarf willow," to humans. Generally, willow species contain salicin, which is a precursor to aspirin and can be toxic in large quantities. Ingesting parts of the dwarf willow plant could potentially lead to symptoms similar to aspirin overdose, such as stomach pain, nausea, vomiting, and in severe cases, kidney failure, seizures, or even coma. The actual risk and severity of symptoms would likely depend on the quantity ingested and the individual's sensitivity.
To pets
As with their potential effects on humans, the toxicity of Salix nakamurana var. yezoalpina, commonly referred to as "dwarf willow," to pets is not well-documented. Generally, willow species contain salicin, which can be harmful in high doses. Symptoms of willow poisoning in pets might include gastrointestinal upset, such as vomiting and diarrhea, and more serious side effects could be similar to those of salicylate (aspirin) toxicity, leading to gastric ulceration, metabolic acidosis, kidney dysfunction, or neurological problems. The severity of symptoms would be dependent on the amount consumed and the specific sensitivity of the pet.

Water
Japanese Willow or Yezo Alpina requires consistent moisture but should not be waterlogged. It thrives best when given deep watering every week, especially during the growing season or at least whenever the top inch of the soil feels dry to the touch. Aim to provide between 1 to 2 gallons of water for each watering session to ensure the soil is thoroughly moistened. During the hot summer months, you may need to increase the frequency to twice a week to prevent the soil from drying out completely. In winter, you can reduce watering as the plant's water requirements decrease.
Light
The Japanese Willow prefers full sun to partial shade, with a preference for sun-drenched locations that receive several hours of direct sunlight each day. It will perform best when placed in a spot where it can enjoy morning sunlight followed by light afternoon shade, which helps protect it from the intense heat of the day.
Temperature
Japanese Willow is hardy and can withstand cold temperatures down to about -20 to -30 degrees Fahrenheit, making it suitable for cooler climates. The ideal growing temperature range for this plant is between 50 to 75 degrees Fahrenheit. While it can tolerate a variety of temperatures, extreme heat above 95 degrees Fahrenheit may stress the plant and require additional care.
Pruning
Pruning the Japanese Willow promotes a strong structure, removes dead or damaged branches, and encourages fresh growth. It is best to prune in late winter or early spring before new leaves emerge. Thin out crowded branches and shape the tree as needed, focusing on maintaining its natural form. Pruning should occur at least once a year or more frequently to address any wayward growth.
Cleaning
As needed
Soil

Repotting
Creeping Willow should be repotted every 2 to 3 years to refresh the soil and accommodate root growth, preferably in the spring.
Humidity & Misting
Creeping Willow thrives in moderate to high humidity levels, mimicking its natural alpine and riverside habitats.
Suitable locations
Indoor
Provide bright light, moist soil, and maintain high humidity for Creeping Willow.
Outdoor
Plant in sun to partial shade, keep soil moist, and protect from strong winds for Creeping Willow.
Hardiness zone

Life cycle
Salix nakamurana var. yezoalpina, more commonly known as Yezo-alpine willow, begins its life cycle as a seed, typically dispersed by wind or water. After landing in a suitable moist and cool alpine habitat, the seed germinates in spring, establishing a root system and sending up shoots. As a fast-growing willow, it quickly develops into a small, hardy shrub with multiple stems and leaves, reaching maturity in just a few years. During its reproductive phase, Yezo-alpine willow produces flowers, known as catkins, which are pollinated by insects. After pollination, seeds are produced and dispersed, continuing the reproductive cycle. The plant has a perennial life cycle, with individual shrubs capable of surviving for multiple years in the harsh alpine environment before eventually dying, either from environmental stress or senescence.
Propogation
Propogation time
Spring
Propogation: For the plant known as Sakhalin Willow, the most popular method of propagation is by using cuttings. This process typically takes place during the plant's dormancy period, which usually falls in the late winter or early spring. The process involves taking cuttings of new growth, approximately 6 to 8 inches (15 to 20 centimeters) in length, and planting them in a moist potting mix or directly in the ground where they are to grow. The cuttings should be placed such that at least two sets of leaf nodes are buried, which will encourage root growth. It is important to keep the soil consistently moist until the cutting has established a strong root system, after which it can be treated as a mature plant.
