Walpole’s Small Camas: A Rare Pacific Northwest Native Worth Protecting
If you’ve stumbled across the name Walpole’s small camas (Camassia quamash walpolei) in your native plant research, you’ve discovered one of the Pacific Northwest’s botanical rarities. This perennial forb represents a unique piece of Oregon’s natural heritage, though it’s not necessarily the best choice for the average home gardener.
What Makes This Plant Special?
Walpole’s small camas belongs to the broader camas family, those beloved spring bloomers that once formed the backbone of Indigenous food systems across the Pacific Northwest. As a herbaceous perennial forb, this plant lacks woody stems and dies back to underground bulbs each winter, emerging fresh each spring like nature’s own resurrection story.
The botanical name Camassia quamash walpolei tells us this is a specific form of the common camas, with some sources also referring to it as Quamasia walpolei Piper. But here’s where things get interesting – and a bit concerning.
A Conservation Concern
Walpole’s small camas carries a Global Conservation Status of S5T1T3, which signals significant rarity concerns. This classification means we’re dealing with a plant that’s extremely uncommon and potentially vulnerable. Currently, it’s documented only in Oregon, making it a true regional endemic.
Important note for gardeners: Due to its rare status, this plant should only be grown using responsibly sourced material, if available at all. Wild collection is strongly discouraged and may be illegal.
Geographic Distribution
This rare camas variety calls Oregon home, though its exact distribution within the state appears to be quite limited. As a native species to the lower 48 states, it represents part of our country’s natural botanical diversity that deserves protection.
Should You Grow Walpole’s Small Camas?
Here’s the honest answer: probably not. The extreme rarity of this plant means it’s likely not available through normal gardening channels, and even if it were, responsible conservation practices suggest leaving rare plants to specialized conservation efforts rather than general cultivation.
Better Alternatives for Your Garden
If you’re drawn to the idea of growing camas in your Pacific Northwest garden, consider these more readily available and equally beautiful alternatives:
- Common Camas (Camassia quamash) – The parent species offers the same spring beauty without conservation concerns
- Great Camas (Camassia leichtlinii) – A taller, showier cousin perfect for naturalizing
- Elegant Camas (Camassia leichtlinii subsp. suksdorfii) – Another stunning Pacific Northwest native
Growing Camas Successfully
While specific growing information for Walpole’s small camas is limited due to its rarity, camas plants generally prefer:
- Moist conditions during spring growing season
- Well-draining soil that dries out somewhat in summer
- Full sun to partial shade
- Cool, wet winters and warm, dry summers (classic Pacific Northwest climate)
The Bigger Picture
Sometimes the most responsible way to appreciate a rare plant is to admire it from afar and support conservation efforts rather than trying to grow it ourselves. Walpole’s small camas serves as a reminder that our native plant communities include species so specialized and rare that their primary value lies in their wild existence rather than their garden potential.
If you’re passionate about supporting rare Pacific Northwest natives, consider donating to local botanical conservation organizations or participating in habitat restoration projects where such rarities might naturally occur.
For your garden, stick with the more common camas species – they’ll give you all the spring beauty and ecological benefits you’re seeking while leaving the rare treasures like Walpole’s small camas to flourish in their natural homes.
