Plant Overview
Often called the Retuse-leaved Willow or the Blunt-leaved Willow, this tiny alpine wonder is a master of survival in the high mountains of Europe. Unlike its towering cousins that weep over riverbanks, Salix retusa forms a lush, green carpet that hugs the earth to escape the biting winds of the Alps and Pyrenees. It is essentially a "forest" that forgot to grow tall, making it a favorite for rock garden enthusiasts.
🔍 How to Identify
- 🍃 The Leaves: Small, oval, and glossy green. The defining feature is the "retuse" tip—a slight notch or indentation at the end of the leaf, as if a tiny, rounded bite was taken out of the apex.
- 🪵 Growth Habit: This is a "prostrate" shrub, meaning it creeps horizontally along the ground. Its woody branches often take root where they touch the soil, creating a dense, living mat that rarely exceeds a few inches in height.
- 🧶 The Catkins: In late spring, it produces upright, yellow-green catkins (flower spikes) that stand like tiny, fuzzy candles against the green foliage.
🏡 In Your Garden
- 🏔️ Rock Garden Specialist: This plant is the ultimate choice for alpine troughs or rockeries. It thrives in crevices where its roots can stay cool and moist while its leaves soak up the mountain sun.
- 💧 The "Thirsty Mountaineer": While it loves rocky drainage, it is not a desert plant. It is used to melting snow and mountain mists, so it hates drying out completely. It prefers acidic to neutral soil that remains consistently damp but never soggy.
⚠️ Safety & Toxicity
- 🐾 Safe Status: Salix retusa is generally considered non-toxic to humans, cats, and dogs.
- 💊 The Aspirin Connection: Like almost all members of the Willow family, the bark contains salicin, the natural precursor to modern aspirin. While not "poisonous," it is best to discourage pets from chewing on the woody stems, as it could cause a mild stomach upset or a bitter taste.
✨ Fun Fact
Salix retusa is considered a glacial relic. As the ice sheets retreated after the last Ice Age, this plant followed the cold, eventually becoming "trapped" on high mountain peaks. It now lives on these high-altitude "islands," separated from other populations by thousands of miles of warm lowlands.

Salix Retusa, also known as the corkscrew willow, is a small shrub or tree that can be grown successfully with the following tips:
- Choose the right location: Salix Retusa prefers a sunny location with moist, well-draining soil. Make sure to choose a spot that receives at least 6 hours of sunlight a day.
- Planting: Plant your Salix Retusa in the spring or fall, digging a hole that is at least twice as wide and deep as the root ball. Make sure to water the plant thoroughly after planting.
- Watering: Salix Retusa needs consistent moisture, especially during the growing season. Water the plant regularly, making sure the soil is moist but not waterlogged.
- Fertilizing: Feed your Salix Retusa with a balanced fertilizer once a year in the spring. Avoid over-fertilizing, as this can cause the plant to become leggy and weak.
- Pruning: Prune your Salix Retusa in the late winter or early spring to control its size and shape. Remove any dead or damaged branches, as well as any crossing or crowded branches.
- Mulching: Mulch around the base of the plant to help retain moisture and suppress weeds. Make sure to leave a gap between the mulch and the trunk of the tree to prevent rot.
By following these tips, you can successfully grow and care for your Salix Retusa plant.
Place in a bright room that is sun drenched almost all day. Or directly in a south-facing window.
Salix retusa is a perennial shrub that is a member of the Salicaceae family. To water this plant, you should first check the soil moisture level using a soil moisture meter or by sticking your finger into the soil. If the top 1-2 inches of soil are dry, then it is time to water the plant.
When watering, you should aim to provide evenly moist soil. This can be achieved by watering deeply, making sure to saturate the soil to the root level. Watering in the early morning or late evening is best, as midday heat can cause water to evaporate quickly. It is important to avoid getting water on the foliage, as this can lead to disease and fungal infections.
The frequency of watering will depend on various factors, including the size of the plant, the temperature and humidity of your environment, and the type of soil the plant is growing in. In general, you should water Salix retusa more frequently during periods of hot, dry weather, and less frequently during colder, wetter months.
To fertilize Salix Retusa plant, apply a balanced fertilizer with an N-P-K ratio of 10-10-10 in early spring before new growth appears. Be sure to water the plant thoroughly after fertilizing to help the nutrients penetrate the soil. Avoid fertilizing in late summer or fall as this can encourage new growth that may be susceptible to winter frost damage. Repeat fertilization every 4-6 weeks during the growing season to promote healthy growth and development.
Salix retusa requires a well-draining, moist soil. It grows best in a soil that is slightly acidic to neutral pH level. A mix of organic matter such as compost or peat moss can be added to improve the soil's fertility and water retention. It is also important to avoid using soils that are heavy in clay or sandy, as they may not provide the necessary nutrients for the plant to thrive. A regular fertilization schedule can help ensure the plant receives the nutrients it needs to grow healthy and strong. Additionally, maintaining the proper soil moisture levels is essential for the growth and survival of this plant.
Salix Retusa can be propagated through various methods, including softwood cuttings, hardwood cuttings, and division.
To propagate Salix Retusa through softwood cuttings, select a healthy stem from the parent plant that is new and flexible, usually in the spring or early summer. Cut the stem to a length of about 4-6 inches, making sure to include at least two sets of leaves. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in well-draining soil and keep it consistently moist until roots develop.
For hardwood cuttings, select a mature stem from the parent plant that is woody and firm, typically in the fall or winter. Cut the stem to a length of about 8-12 inches and remove any leaves. Dip the bottom end in rooting hormone and plant it in a container with a mixture of sand and peat moss. Keep the soil moist and place the container in a warm, bright location until roots form.
Alternatively, Salix Retusa can also be propagated through division. Carefully dig up the parent plant and separate it into smaller sections, making sure each section has roots attached. Replant the divisions in individual pots or directly in the ground, ensuring they receive adequate water and light to promote new growth.
Overall, propagating Salix Retusa can be a rewarding process that allows for the cultivation of new plants from an existing specimen. By following these methods carefully, gardeners can expand their collection of Salix Retusa plants and enhance their landscape with the unique characteristics of this species.
