Southwestern Black Cherry: A Hidden Gem for Arid Native Gardens
Meet Prunus serotina var. rufula, a fascinating southwestern variety of the well-known black cherry. While its eastern cousin gets most of the attention, this resilient shrub deserves a spot in your native plant vocabulary—especially if you’re gardening in the arid Southwest!
What Makes This Plant Special?
This perennial shrub is the desert-tough cousin of the familiar black cherry tree. Instead of towering like its eastern relatives, Prunus serotina var. rufula typically stays more manageable as a multi-stemmed shrub, usually reaching heights of 13-16 feet, though it can surprise you by growing up to 40 feet under ideal conditions.
You might also encounter this plant listed under its synonym Prunus virens var. rufula, but don’t let the name confusion fool you—it’s the same hardy character.
Where Does It Call Home?
This native beauty has quite the limited range, calling only three states home: Arizona, New Mexico, and Texas. If you’re gardening in these southwestern states, you’re in luck—this plant has been thriving in your region for centuries and knows exactly how to handle your local conditions.
Garden Appeal and Landscape Role
Here’s where this shrub really shines in the garden:
- Spring blooms: Clusters of conspicuous white flowers appear in early spring, creating a stunning display
- Summer foliage: Dense, medium-textured green leaves provide excellent screening and privacy
- Fall interest: The foliage puts on a conspicuous fall show before dropping
- Purple fruits: Conspicuous purple fruits appear from summer through fall
- Winter structure: Multiple stems create interesting winter architecture
With its rapid growth rate and erect, multi-stem form, this shrub works beautifully as a privacy screen, windbreak, or specimen plant in native gardens and xeriscapes.
Perfect Growing Conditions
One of the best things about this southwestern native? It’s incredibly adaptable and tough as nails:
- Soil flexibility: Happy in coarse, medium, or fine-textured soils

- Drought tolerance: Excellent once established, needing only 9-35 inches of annual precipitation
- Sun requirements: Intermediate shade tolerance, but thrives in full sun
- Cold hardy: Tolerates temperatures down to -23°F
- Fire resistance: Both fire-resistant and fire-tolerant—a valuable trait in fire-prone areas
The plant requires at least 160 frost-free days, making it well-suited to its native southwestern range.
USDA Hardiness Zones
While specific hardiness zone information for this variety isn’t widely documented, based on its native range in Arizona, New Mexico, and Texas, plus its cold tolerance to -23°F, it’s likely suitable for USDA zones 6-9.
Planting and Care Tips
Getting started with southwestern black cherry is easier than you might think:
