Elizabeth’s Milkvetch: A Rare Gem for the Dedicated Native Plant Gardener
Meet Elizabeth’s milkvetch (Astragalus desperatus var. neeseae), a charming little perennial that’s about as exclusive as native plants get. This low-growing member of the pea family might not be the showiest plant in your garden, but for native plant enthusiasts looking for something truly special, it’s a real treasure.
What Makes Elizabeth’s Milkvetch Special?
This petite perennial stays compact, typically growing as a low shrub under 1.5 feet tall and never exceeding 3 feet at maturity. Don’t let its modest size fool you – this little plant packs personality with its silvery-green compound leaves and delicate white to cream-colored pea-like flowers that bloom in spring.
Elizabeth’s milkvetch is a true native of the American West, calling Colorado and Utah home. You’ll find it naturally growing in desert shrublands and pinyon-juniper communities, where it has adapted to some pretty tough conditions.
A Word of Caution: Rarity Matters
Here’s something important to know before you start dreaming of adding this plant to your garden: Elizabeth’s milkvetch has a Global Conservation Status that indicates it’s quite rare. If you’re interested in growing this special plant, please make sure you source it responsibly from reputable native plant nurseries that propagate rather than wild-collect their plants. Never harvest from wild populations.

This isn’t your typical garden center find, and frankly, that’s part of its appeal. Elizabeth’s milkvetch is perfect for:
- Native plant gardens showcasing Colorado and Utah flora

The plant thrives in USDA hardiness zones 4-8, making it suitable for gardeners in much of the mountain West and similar climates.
Growing Conditions and Care
Like many desert natives, Elizabeth’s milkvetch appreciates the tough love approach to gardening:
- Sunlight: Full sun is essential
- Soil: Well-draining sandy or rocky soils work best
- Water: Drought tolerant once established; avoid overwatering
- Maintenance: Minimal care required – this plant prefers benign neglect
Pollinator and Wildlife Benefits
As a member of the legume family, Elizabeth’s milkvetch attracts native bees and other small pollinators during its flowering period. While specific wildlife benefits aren’t well-documented, most Astragalus species provide some value to local ecosystems through their relationships with native pollinators.
The Bottom Line
Elizabeth’s milkvetch isn’t for everyone, and that’s okay. This is a plant for gardeners who appreciate rarity, want to support conservation through cultivation, and enjoy the challenge of growing something truly unique. If you can source it responsibly and provide the right growing conditions, you’ll have a conversation starter that few other gardeners can claim.
