Bessey’s Locoweed: A Rare Rocky Mountain Native Worth Knowing
If you’re drawn to the unique challenge of growing rare native plants, Bessey’s locoweed might just capture your gardening heart. This distinctive Rocky Mountain native brings a touch of high-altitude charm to specialized gardens, though it’s definitely not your typical backyard flower.
What Makes Bessey’s Locoweed Special
Scientifically known as Oxytropis besseyi var. obnapiformis, Bessey’s locoweed is a perennial forb that’s perfectly adapted to life in harsh mountain conditions. As a member of the pea family, this low-growing plant produces charming purple to pink flowers that seem almost too delicate for the rugged environments where they naturally thrive.
This plant is a true native of the American West, calling Colorado, Utah, and Wyoming home. It’s found naturally in alpine and subalpine regions where most other plants simply can’t survive.
Important Conservation Note
Before we dive into growing tips, here’s something crucial to know: Bessey’s locoweed has a conservation status that suggests it may be uncommon in parts of its range. If you’re interested in adding this plant to your garden, make absolutely sure you’re sourcing it responsibly from reputable native plant nurseries—never collect from the wild.
Garden Appeal and Design Uses
Bessey’s locoweed isn’t going to wow you with size—this is a compact, ground-hugging plant that makes its statement through subtle beauty rather than bold presence. Here’s what makes it garden-worthy:
- Unique pea-like flowers in soft purple-pink tones
- Excellent for rock gardens and alpine plant collections
- Perfect conversation starter for native plant enthusiasts
- Provides authentic Rocky Mountain character
Where Bessey’s Locoweed Thrives
This isn’t a plant for every garden situation. Bessey’s locoweed is best suited for:
- Specialized rock gardens
- Alpine plant collections
- Native plant demonstration gardens
- Xerophytic (dry) landscape designs
It’s particularly at home in USDA hardiness zones 4-7, where it can experience the cold winters it actually needs to thrive.
Growing Conditions: Mimicking the Mountains
Growing Bessey’s locoweed successfully means understanding its mountain origins. This plant demands:
- Excellent drainage: Think sandy, rocky, or gravelly soil
- Full sun exposure: At least 6-8 hours daily
- Minimal water: Drought tolerance is its superpower
- Good air circulation: Prevents fungal issues
- Alkaline to neutral soil pH: Mirrors its native limestone habitats
Planting and Care Tips
Successfully growing Bessey’s locoweed requires patience and the right approach:
- Soil prep is everything: Amend heavy soils with coarse sand and gravel for drainage
- Plant in spring: After the last frost but while cool weather persists
- Water sparingly: Only during establishment, then rely on natural rainfall
- Avoid fertilizers: This plant thrives in poor soils
- Provide winter protection: In harsh climates, a gravel mulch helps
Wildlife and Pollinator Benefits
While small in stature, Bessey’s locoweed pulls its weight in supporting local ecosystems. The flowers attract native bees and other specialized pollinators that have co-evolved with Rocky Mountain plants. It’s particularly valuable for supporting high-elevation pollinator communities.
Is Bessey’s Locoweed Right for Your Garden?
This plant is definitely for specialized gardeners rather than casual landscapers. Consider Bessey’s locoweed if you:
- Love collecting rare and unusual native plants
- Have experience with alpine or desert plants
- Want to support native biodiversity
- Enjoy gardening challenges
- Have the right growing conditions (excellent drainage is non-negotiable)
However, skip this plant if you’re looking for easy-care options or dramatic garden impact. Its subtle beauty and specific needs make it better suited for dedicated native plant gardens than general landscaping.
The Bottom Line
Bessey’s locoweed offers a unique opportunity to grow a rare piece of Rocky Mountain heritage in your garden. While it’s not the easiest plant to cultivate, success brings the satisfaction of preserving a special native species while supporting local pollinators. Just remember to source responsibly and be prepared for a rewarding but challenging gardening adventure.
