Blanketleaf Willow: A Rare Northern Native Worth Knowing
If you’re gardening in Canada’s northern regions and love supporting native plants, you might want to learn about the blanketleaf willow (Salix silicicola). This perennial shrub is one of those special native plants that deserves more attention – though with an important caveat about its conservation status that we’ll discuss.
What is Blanketleaf Willow?
Blanketleaf willow is a multi-stemmed woody shrub that typically stays under 13-16 feet tall, making it a manageable size for most landscapes. Like other willows, it’s a perennial that comes back year after year, developing into a lovely shrub with several stems arising from or near the ground.
You might also see this plant listed under its botanical synonym Salix alaxensis var. silicicola in some references, but Salix silicicola is the accepted current name.
Where Does It Grow Naturally?
This willow is native to Canada, with documented populations in Saskatchewan and Nunavut. It’s adapted to some pretty harsh northern conditions, which tells us it’s one tough little shrub!
Important Conservation Note
Here’s something crucial to know: blanketleaf willow has a Global Conservation Status of S2S3, which indicates it may be rare or uncommon in its native range. This means if you’re interested in growing this plant, you should only source it from reputable native plant nurseries that practice ethical collection methods. Never collect from wild populations, as this could harm already vulnerable natural stands.
Why Consider This Native Willow?
While detailed cultivation information for this specific willow is limited, native willows in general offer several benefits:
- Support for native wildlife and ecosystems
- Adaptation to local climate conditions
- Potential early-season pollen source for beneficial insects
- Natural beauty that fits the local landscape
Growing Conditions and Care
Given its northern native range, blanketleaf willow is likely very cold hardy – perfect for gardeners dealing with harsh winters. Like most willows, it probably appreciates:
- Adequate moisture (willows rarely like drought)
- Full sun to partial shade
- Well-draining soil that doesn’t stay waterlogged
Since specific growing information for Salix silicicola is limited, if you’re lucky enough to find this plant at a native plant sale, ask the grower about their experience with its particular needs.
Landscape Role
This shrub could work well in:
- Native plant gardens
- Wildlife-friendly landscapes
- Cold-climate gardens needing tough, attractive shrubs
- Areas where you want to support local biodiversity
The Bottom Line
Blanketleaf willow represents an interesting opportunity for northern gardeners to grow a truly local native plant. However, its apparent rarity means this isn’t a plant you’ll find at your typical garden center. If conservation-minded gardening appeals to you and you live in its native range, keep an eye out for this species at native plant sales – but always verify that any plants are ethically and sustainably sourced.
For most gardeners, you might consider other native willow species that are more readily available and less conservation-sensitive, while still providing many of the same ecological benefits.
