Origin:
Salix arctica Pallas var. graminifolia (E.H. Kelso) L. Kelso, commonly known as Arctic willow or Graminifolia willow, is a species of willow that belongs to the family Salicaceae. It is native to the Arctic and subarctic regions of North America, Europe, and Asia. The plant can be found in tundras, rocky hillsides, and along mountain streams.
Description:
The Arctic willow is a small deciduous shrub that can grow up to 30 centimeters in height. The plant's stems are thin, wiry, and reddish-brown while its leaves are narrow, linear, and light green in color. The leaves are about 1-4 cm long, and they curl up at the edges. During the flowering season, which occurs between May and June, the plant produces catkins that are 1-3 cm in length. The catkins can be either male or female, and they are pollinated by the wind. Arctic willow has a shallow root system that can quickly colonize new sites.
Common Names:
Arctic Willow is known by several common names like Graminifolia willow and Arctic willow.
Uses:
The Arctic willow has several uses in traditional medicine as it contains salicylic acid, which is the active ingredient in aspirin. The plant's bark, leaves, and twigs have been used to treat a range of ailments, including headaches, pain, fever, and inflammation. The plant is also used for erosion control and re-vegetation of disturbed sites. Its roots help stabilize the soil, and the plant's small size makes it a valuable component in habitat restoration projects. The Arctic willow is also an important source of food for many animals, including moose, musk oxen, hares, and lemmings, especially during the winter months.
Light Requirements

Salix arctica Pallas var. graminifolia grows well in moist, well-draining, and slightly acidic soils. They can tolerate a wide range of soil types, including sandy soils and gravelly soils. They are adapted to growing in areas with low nutrients and can survive in poor soils. However, they will grow best when provided with some organic matter and a slow-release fertilizer.
Cultivation Methods for Salix arctica Pallas var. graminifolia (E.H. Kelso) L. Kelso
Salix arctica Pallas var. graminifolia (E.H. Kelso) L. Kelso, commonly known as Arctic willow, is a small, but hardy plant that grows mostly in cold and arctic regions. It is mostly propagated through seeds or cuttings and can be grown in different types of soil, including loam, sandy and clay soils.
For successful cultivation, it is recommended to plant seeds or cuttings in early spring after the soil has thawed and warmed up slightly. The plant should be planted in a place with good drainage and direct sunlight as it is a sun-loving plant.
Watering Needs of Salix arctica Pallas var. graminifolia (E.H. Kelso) L. Kelso
The Arctic willow has moderate water needs and can tolerate short periods of drought. When planted in the ground, regular watering should be done during prolonged dry periods.
For cultivated plants, it is helpful to keep the soil moist, but not waterlogged, to help the plant grow strong roots. Watering should be done in the early morning or evening when the temperatures are cooler.
Fertilization of Salix arctica Pallas var. graminifolia (E.H. Kelso) L. Kelso
Arctic willows are light feeders, and they don't require heavy fertilization. Too much fertilizer can cause damage to the plant, so it is recommended to apply a balanced fertilizer sparingly once a year, preferably in late fall or early spring.
The recommended fertilizer ratio for salix arctica pallas var. graminifolia is 10-10-10, or any other balanced NPK fertilizer that contains trace minerals such as iron, magnesium, and copper.
Pruning Techniques for Salix arctica Pallas var. graminifolia (E.H. Kelso) L. Kelso
Pruning can help Arctic willows maintain their shape and size. The best time to prune is during the dormant season, either in late winter or early spring.
The plant should be pruned using clean, sharp pruning shears to avoid damaging the plant. Dead or diseased branches should be removed first, followed by any branches that are crossing or rubbing against each other.
To encourage new growth, the tips of the branches can be lightly trimmed, but the overall shape of the plant should not be altered too much, as doing so can cause structural damage to the plant.
Propagation Method for Salix arctica Pallas var. graminifolia (E.H. Kelso) L. Kelso
Salix arctica Pallas var. graminifolia (E.H. Kelso) L. Kelso, also known as Arctic Willow, is propagated through different methods:
Seed Propagation
Salix arctica Pallas var. graminifolia can be propagated through seeds. The seeds should be collected when they are matured or when the capsules are fully opened. Seeds that are not yet properly matured may require cold stratification before planting. The seed planting area must be prepared by plowing and tilling to create a good seed bed. Ensure that the seeds are sown evenly and at a depth of about 1.5 to 2.5 centimeters. Keep the soil moist by watering at least once every day. Within two weeks after planting, the first germination should start to occur.
Cutting Propagation
Salix arctica Pallas var. graminifolia can be propagated through cuttings. The best time to take cuttings is in the late summer when the plant has finished growing its seasonal shoots. Ensure that the cuttings are taken from healthy, vigorous parent plants. The cuttings should be about 20 centimeters or less and should contain at least two nodes. Place the cuttings in a container filled with a rooting hormone solution and keep it moist until the roots have formed, which should happen within several weeks.
Layering Propagation
Another method of propagating Salix arctica Pallas var. graminifolia is through layering. This process involves bending a low-lying stem down to the ground and covering it with soil. The nodes on the stem should be in contact with the soil. The covered nodes will start to grow roots over time while still attached to the parent plant. Once the roots have formed sufficiently, the new plant can be cut from the parent plant and transplanted to a new location.
