Silky Lupine: A Native Oregon Beauty Worth Discovering
Meet Lupinus sericeus sericeus var. thompsonianus, better known as silky lupine – a charming native perennial that calls Oregon home. While this particular variety might not be as well-known as some of its lupine cousins, it represents an authentic piece of Pacific Northwest flora that deserves a closer look from native plant enthusiasts.
What Makes Silky Lupine Special?
This lovely native is a true perennial forb, meaning it’s a non-woody plant that comes back year after year. Unlike shrubs or trees, silky lupine stays relatively low to the ground and puts its energy into those gorgeous flower spikes that lupines are famous for. As a member of the legume family, it has the neat trick of fixing nitrogen in the soil – basically giving your garden a natural fertility boost!
Where Does It Come From?
Silky lupine is proudly native to Oregon, making it a fantastic choice for gardeners wanting to support local ecosystems and wildlife. When you plant native species like this one, you’re essentially rolling out the welcome mat for the birds, bees, and butterflies that co-evolved with these plants over thousands of years.
Should You Plant Silky Lupine?
Here’s where things get a bit interesting. This particular variety has a conservation status that’s currently listed as undefined (S5T3?), which means scientists aren’t entirely sure about its population status. This doesn’t necessarily mean it’s endangered, but it does suggest we should treat it with extra care.
The upside: You’d be supporting native biodiversity and potentially helping preserve a piece of Oregon’s natural heritage. Native plants are typically easier to grow once established since they’re adapted to local conditions.
The consideration: With limited information about this specific variety’s cultivation needs and conservation status, it’s definitely a plant for the more adventurous native gardener.
Growing Silky Lupine: What We Know
Unfortunately, detailed cultivation information for this specific variety is quite limited. However, as a native Oregon perennial, we can make some educated guesses about its preferences:
- Likely adapted to Oregon’s climate patterns
- Probably prefers well-draining soil (most lupines do)
- May benefit from some summer drought tolerance, typical of many Pacific Northwest natives
- Being a legume, it likely doesn’t need rich, fertilized soil
The Responsible Approach
If silky lupine has caught your interest, here’s how to proceed thoughtfully:
- Source responsibly: Only purchase from reputable native plant nurseries that can verify the plant’s origin
- Never collect from the wild: Given the uncertain conservation status, wild collection could be harmful
- Start small: Try one plant first to see how it performs in your specific garden conditions
- Connect with local experts: Reach out to Oregon native plant societies or extension services for local growing advice
Alternative Native Options
If you’re drawn to lupines but want something with more established cultivation information, consider these other Pacific Northwest natives:
- Lupinus polyphyllus (large-leaved lupine)
- Lupinus littoralis (seashore lupine)
- Other native Oregon wildflowers like camas or Oregon sunshine
The Bottom Line
Silky lupine represents the exciting challenge and reward of growing lesser-known native plants. While we don’t have all the cultivation details figured out yet, adventurous gardeners who source plants responsibly could play a valuable role in learning more about this Oregon native while supporting local biodiversity. Just remember – with great native plants comes great responsibility to source and grow them ethically!
