Spinescale Saltbush: A Hardy California Native for Water-Wise Gardens
Meet the spinescale saltbush (Atriplex spinifera), a tough-as-nails California native that’s perfectly suited for gardeners looking to create stunning, drought-tolerant landscapes. This unassuming perennial shrub might not win any beauty contests with flashy flowers, but what it lacks in showiness, it more than makes up for in resilience and ecological value.
What Makes Spinescale Saltbush Special?
Spinescale saltbush is a true California original, native exclusively to the Golden State. As a perennial, multi-stemmed woody shrub, it typically grows less than 13 to 16 feet in height, though it usually stays much more compact in garden settings. Its several stems arise from or near the ground, creating a bushy, informal appearance that works beautifully in naturalistic landscapes.
This hardy plant calls California home, thriving in the state’s diverse desert and semi-arid regions.
A Word About Conservation
Before you rush out to plant spinescale saltbush, there’s something important to know: this species has a Global Conservation Status of S3S4, indicating it faces some level of conservation concern. While this doesn’t mean you shouldn’t grow it, it does mean you should source your plants responsibly from reputable native plant nurseries rather than collecting from the wild. By choosing nursery-grown plants, you’re supporting conservation efforts while enjoying this wonderful native species.
