Calder’s Bladderpod: An Arctic Treasure for the Most Adventurous Gardeners
Meet Calder’s bladderpod (Lesquerella calderi), a hardy little perennial that calls some of the coldest places in North America home. This member of the mustard family might not be heading to your local nursery anytime soon, but it’s worth getting to know – especially if you’re fascinated by plants that thrive where most others fear to tread.
What Is Calder’s Bladderpod?
Calder’s bladderpod is a native perennial forb, meaning it’s a non-woody herbaceous plant that returns year after year. True to its mustard family heritage, this Arctic resident produces small yellow flowers that add a cheerful splash of color to the tundra landscape during its brief growing season.
Where Does It Call Home?
This tough little plant is native to the far northern reaches of North America, specifically:
- Alaska
- Yukon Territory
- Northwest Territories
It’s perfectly adapted to life in Arctic and subarctic conditions, thriving in environments that would challenge even the hardiest of garden plants.
Should You Grow Calder’s Bladderpod?
Here’s where we need to have a frank conversation. Unless you’re gardening in an extremely cold climate (think USDA zones 1-3) and have experience with specialized alpine or arctic plants, Calder’s bladderpod probably isn’t the right choice for your garden.
This plant has evolved specifically for arctic conditions and requires:
- Extremely cold winters
- Cool, short summers
- Well-draining soil similar to tundra conditions
- Specialized care that mimics its native habitat
Conservation Considerations
Before you even consider growing Calder’s bladderpod, it’s important to know that this species has a conservation status of S3S4, meaning it ranges from vulnerable to apparently secure in different parts of its range. If you’re determined to grow this plant, please ensure you’re sourcing it responsibly from reputable suppliers who don’t harvest from wild populations.
For the Arctic Gardener
If you happen to live in the far north and want to try your hand at growing native arctic plants, Calder’s bladderpod could be an interesting addition to a specialized rock garden or naturalized arctic landscape. However, expect it to be quite challenging to establish and maintain.
Wildlife and Pollinator Value
In its native habitat, Calder’s bladderpod likely provides nectar and pollen for cold-adapted insects and other pollinators during the brief arctic growing season. However, specific wildlife benefits aren’t well documented for this species.
Better Alternatives for Most Gardeners
If you’re drawn to the idea of mustard family plants but live in a more temperate climate, consider these native alternatives that are much more garden-friendly:
- Wild bergamot (Monarda species)
- Purple prairie clover (Dalea purpurea)
- Local native wildflowers in the Brassicaceae family
The Bottom Line
Calder’s bladderpod is a fascinating example of plant adaptation to extreme environments, but it’s not a plant for the average gardener. Unless you’re specifically working with arctic native plants in an appropriate climate, you’ll have much better success (and do more for local ecosystems) by choosing native plants that are adapted to your specific region.
Sometimes the most interesting plants are the ones we admire from afar – and that’s perfectly okay!
