Where Does Shockley’s Milkvetch Call Home?

Before we dive into growing tips, here’s something important: Shockley’s milkvetch has a conservation status that suggests it’s not super common in the wild.

Our desert ecosystems need all the help they can get!

Growing Conditions That Make It Happy
Shockley’s milkvetch isn’t fussy, but it does have some preferences rooted in its desert heritage:
- Sunlight: Full sun is essential – this plant loves those bright, sunny days
- Soil: Well-draining sandy or rocky soils work best; avoid heavy clay that holds moisture
- Water: Drought tolerant once established, but appreciates occasional deep watering during extremely dry periods
- Climate: Thrives in USDA hardiness zones 8-10
Planting and Care Tips
Getting Shockley’s milkvetch established is pretty straightforward if you follow these guidelines:
- Best planting time: Fall planting gives roots time to establish before summer heat
- Soil preparation: Improve drainage by adding coarse sand or gravel if needed

- Maintenance: Minimal pruning needed; let it follow its natural growth pattern
Supporting Pollinators
