A Unique, Compact Willow With Four‑Season Interest
Salix purpurea ‘Nana’, commonly known as the Dwarf Arctic Willow, is one of the most charming and underused shrubs in the landscape. Unlike the large, unruly willows many gardeners picture, this cultivar is compact, rounded, and incredibly elegant, typically reaching 3–5 feet in height.
Its standout features include:
- Fine, narrow blue‑green foliage
- Attractive red‑purple stems
- A naturally rounded, dome‑shaped habit
- Excellent response to pruning, especially coppicing
I have one in my own garden, and it’s a plant I look forward to working with every spring. A quick coppicing transforms it from winter sticks into a fresh flush of vibrant young stems by early summer.
How to Care for Salix purpurea ‘Nana’
This willow is not demanding, but it does appreciate the right conditions.
Light
- Full sun is ideal
- Tolerates light shade but colour and density improve with sun
Soil
- Prefers moist, well‑drained soil. Although my soil is a heavy clay, (verging on shale!) and does very well.
- More tolerant of wet conditions than many shrubs
- Not fussy about soil pH
Water
- Moderate moisture
- Appreciates consistent watering in the first year
- Once established, relatively drought tolerant (better than many willows)
Growth Habit
- Dense, rounded, often described as “tufted” or “mounded”
- Responds extremely well to hard spring pruning
Why I Coppice My Salix purpurea ‘Nana’ Every Spring
Coppicing is the practice of cutting a woody plant back to just a few inches above the ground each spring to encourage vigorous new growth.
🌱 Why coppice this shrub?
- New stems are stronger in colour
- The plant maintains a compact, ball‑shaped form
- Reduces any winter dieback
- Improves summer foliage density
- Keeps an older plant looking youthful and tidy
Coppicing is easy:
In early spring, before buds break, cut the entire shrub to 4–6 inches above ground level. It will push new shoots quickly, rejuvenating the entire plant.
If you prefer a more natural look, you can skip coppicing, but annual pruning will still help maintain shape and density.
