Kearney’s Sumac: A Hidden Gem for Desert Gardens
If you’re looking for a tough, drought-tolerant native shrub that can handle the desert heat while providing year-round interest, let me introduce you to Kearney’s sumac (Rhus kearneyi). This unassuming Arizona native might not be the flashiest plant in the nursery, but it’s exactly the kind of reliable, low-maintenance performer that smart desert gardeners are seeking.
What Makes Kearney’s Sumac Special?
Kearney’s sumac is a perennial shrub that typically grows as a multi-stemmed woody plant, usually staying under 13-16 feet tall. What sets this plant apart is its incredible resilience and its status as a true Arizona native. While many desert plants struggle with extremes, this sumac has evolved specifically for the challenging conditions of the Sonoran Desert.
The plant produces compound leaves that add fine-textured foliage to the landscape, and in fall, these leaves often develop attractive reddish tones. Small clusters of red berries follow the inconspicuous flowers, providing both visual interest and wildlife value.
Where Does It Naturally Grow?
Kearney’s sumac is native to the lower 48 states, with its primary distribution concentrated in Arizona. You’ll find this hardy shrub naturally occurring in the Sonoran Desert regions, particularly in southern Arizona, where it has adapted to the area’s unique climate and soil conditions.
Why Consider Planting Kearney’s Sumac?
There are several compelling reasons to include this native in your landscape:
- Water-wise choice: Once established, it’s extremely drought tolerant, perfect for xeriscaping
- Native plant benefits: Supports local ecosystems and wildlife
- Low maintenance: Requires minimal care after the establishment period
- Pollinator friendly: The flowers provide nectar for bees and other beneficial insects
- Wildlife habitat: The berries and structure provide food and shelter for desert wildlife
Perfect Garden Settings
Kearney’s sumac shines in specific garden styles and settings:
- Desert and xeriscape gardens
- Native plant landscapes
- Wildlife habitat gardens
- Low-water Mediterranean-style gardens
- Naturalistic desert restorations
This shrub works particularly well as a background plant, in mixed native plantings, or as part of a wildlife corridor. Its modest size makes it suitable for residential landscapes without overwhelming smaller spaces.
Growing Conditions and Care
Kearney’s sumac thrives in USDA hardiness zones 9-10, making it perfect for much of Arizona and similar desert climates. Here’s what this adaptable native needs to succeed:
Ideal Growing Conditions:
- Sunlight: Full sun exposure
- Soil: Well-draining soil is essential; tolerates poor, rocky, or sandy soils
- Water: Drought tolerant once established, but benefits from occasional deep watering
- Climate: Heat tolerant and adapted to low-humidity conditions
Planting and Care Tips
Success with Kearney’s sumac starts with proper planting and early care:
- Best planting time: Fall or early spring when temperatures are moderate

Is Kearney’s Sumac Right for Your Garden?
This native shrub is an excellent choice if you’re gardening in Arizona’s desert regions and want a reliable, low-maintenance plant that supports local wildlife. It’s particularly valuable for gardeners committed to using native plants and creating sustainable, water-wise landscapes.
However, if you’re looking for a showstopper with dramatic flowers or bold architectural form, you might want to pair Kearney’s sumac with more visually striking natives rather than making it a focal point.
The bottom line? Kearney’s sumac may not win any beauty contests, but it’s the kind of steady, dependable native that forms the backbone of successful desert gardens. Give this Arizona native a try, and you’ll likely find yourself appreciating its quiet resilience and ecological value.
