Tenleaf Woodsorrel: A Charming Native for Southwestern Shade Gardens
If you’re looking for a delicate, low-maintenance native plant to brighten up those shady spots in your Arizona or New Mexico garden, let me introduce you to tenleaf woodsorrel (Oxalis decaphylla). This little charmer might not be the most famous native plant on the block, but it’s definitely worth getting to know!





What Makes Tenleaf Woodsorrel Special?
Tenleaf woodsorrel is a true native of the American Southwest, calling Arizona and New Mexico home. As a perennial forb, this herbaceous plant returns year after year without the woody stems of shrubs or trees. Think of it as nature’s way of providing a reliable, soft-textured ground cover that knows exactly how to thrive in your local conditions.
The name tenleaf gives you a hint about its distinctive appearance – this woodsorrel produces charming heart-shaped leaflets arranged in groups, creating an almost clover-like look that’s both familiar and unique. You might also see this plant listed under its botanical synonym, Oxalis grayi, in older gardening references.
Garden Appeal and Design Potential
What really makes tenleaf woodsorrel shine is its understated elegance. The small, bright yellow flowers create cheerful splashes of color against the backdrop of delicate, heart-shaped foliage. It’s the kind of plant that makes you stop and take a closer look – not flashy, but genuinely charming in that hidden gem sort of way.
This native works beautifully as:
- Ground cover in shaded woodland gardens
- An addition to native plant collections
- Part of naturalistic landscape designs
- A charming accent in xeriscape gardens with adequate shade
Growing Conditions and Care
Here’s where tenleaf woodsorrel really proves its worth as a native plant – it’s naturally adapted to thrive in USDA hardiness zones 7-9, which perfectly matches its southwestern native range. This means if you’re gardening in Arizona or New Mexico, you’re working with a plant that’s already programmed for success in your climate.
For the best results, provide your tenleaf woodsorrel with:
- Partial to full shade (it’s not a sun-worshipper!)
- Well-draining soil that doesn’t stay soggy
- Moderate water – more than a true desert plant, but less than thirsty garden favorites
Planting and Maintenance Tips
Spring is your best bet for planting tenleaf woodsorrel. Once you’ve got it in the ground, a layer of mulch will help retain moisture and keep the roots happy. The beauty of working with natives is that they typically require minimal fuss once established – this plant is no exception.
While we don’t have extensive documentation on all aspects of tenleaf woodsorrel’s garden behavior (it’s one of those wonderfully understated natives that hasn’t gotten as much attention as it deserves), its small flowers do provide nectar sources for native bees and other small pollinators, making it a pollinator-friendly choice for your garden.
Should You Plant Tenleaf Woodsorrel?
If you’re gardening in Arizona or New Mexico and have shady spots that need some native charm, tenleaf woodsorrel could be a delightful addition to your landscape. Its native status means it’s naturally suited to your local ecosystem, and its perennial nature provides lasting value without the need to replant annually.
Keep in mind that as a relatively uncommon native plant in cultivation, you might need to seek out specialized native plant nurseries or native plant sales to find it. But that’s part of the adventure of native gardening – discovering and growing the plants that truly belong in your corner of the world!
Whether you’re creating a dedicated native plant garden or simply want to add some authentic regional character to your shaded areas, tenleaf woodsorrel offers a gentle, sustainable way to connect your landscape with the natural heritage of the Southwest.
