Goose Creek Milkvetch: A Rare Treasure for the Dedicated Native Plant Gardener
If you’re the type of gardener who gets excited about growing something truly special—something your neighbors have definitely never heard of—then Goose Creek milkvetch might just capture your imagination. This little-known native wildflower is as rare as it is charming, making it a true collector’s plant for serious native gardening enthusiasts.
What Makes Goose Creek Milkvetch Special?
Astragalus anserinus, commonly known as Goose Creek milkvetch, is a perennial wildflower native to the intermountain West. Don’t let its humble appearance fool you—this plant is botanical gold. With delicate, compound leaves and clusters of small, cream-colored flowers that look like tiny sweet peas, it brings a subtle elegance to any native plant collection.
Where Does It Call Home?
This special milkvetch has chosen some pretty exclusive real estate for its native range. You’ll find it naturally occurring in Idaho, Nevada, and Utah, where it has adapted to the unique conditions of the Great Basin and surrounding areas. It’s truly a child of the American West, evolved to thrive in the region’s distinctive climate and soils.
A Word of Caution: This Plant is Rare
Here’s where things get serious, fellow plant lovers. Goose Creek milkvetch has a Global Conservation Status of S2, which means it’s considered Imperiled. In plain English? This plant is extremely rare, with typically only 6 to 20 known populations and somewhere between 1,000 to 3,000 individual plants remaining in the wild.
What this means for you: If you’re lucky enough to find seeds or plants available, make absolutely sure they come from responsible, ethical sources. Never collect from wild populations, and only purchase from reputable native plant nurseries that propagate their own stock. This isn’t just good practice—it’s essential for the species’ survival.
Growing Your Own Goose Creek Milkvetch
If you can source this plant responsibly, here’s how to give it the royal treatment it deserves:
Perfect Growing Conditions
- Sunlight: Full sun is a must—this desert dweller loves bright, direct light
- Soil: Well-draining soil is absolutely critical; soggy conditions will spell doom
- Water: Drought tolerant once established, but appreciates occasional deep watering during extreme dry spells
- Climate: Hardy in USDA zones 4-7, perfect for areas with hot summers and cold winters
Planting and Care Tips
Think tough love when it comes to caring for Goose Creek milkvetch. This plant evolved in harsh conditions, so your biggest mistake would be killing it with kindness (especially overwatering). Plant in spring, water gently until established, then step back and let nature take its course.
The key to success? Excellent drainage and patience. This isn’t a plant that will give you instant gratification, but for those who appreciate subtle beauty and conservation value, it’s absolutely worth the wait.

Goose Creek milkvetch shines in:

Those charming little flowers aren’t just for show—they’re pollinator magnets for small native bees and other beneficial insects. By growing this plant (responsibly, of course), you’re supporting the complex web of native wildlife that depends on indigenous plants.
The Bottom Line
Goose Creek milkvetch isn’t for everyone, and frankly, that’s probably for the best. This is a plant for gardeners who understand that sometimes the most rewarding plants are those that challenge us, teach us, and connect us to the incredible—and fragile—biodiversity of our native landscapes.
