Bauhinia Lunarioides: Fragrant Texas Native for Dry Gardens

Texasplume (Bauhinia lunarioides), also called Anacacho orchid tree, may look delicate but thrives in rocky, alkaline soil. This drought-tolerant Texas native handles full sun to filtered shade and can be grown as a large shrub or trained into a small tree, adding versatility to the landscape.

• Botanical name: Bauhinia lunarioides (syn. Bauhinia congesta)
• Common names: Texasplume, Anacacho orchid tree, Chihuahuan orchid shrub, white orchid tree
• Origin: Native to southwestern Texas and northeastern Mexico, found in rocky canyons
• Hardiness: Hardy to 15°F (some reports to 10°F), USDA Zone 8
• Water: Moderate; water deeply every 10 days in summer, twice monthly in spring/fall, monthly in winter
• Light: Full sun to filtered shade (avoid western exposure)
• Mature size: 8–12 feet tall, 6–10 feet wide

Distinguishing Traits

Attractive dark green leaves, ¾ to 1 inch long, uniquely shaped like butterfly wings. Fragrant five-petaled flowers (white or pink) resemble small orchids, appearing in spring and lasting into early summer, with possible fall rebloom. Garden-grown shrubs typically have white flowers; pink blossoms are more common in the native Chihuahuan desert.

Landscape Uses

As a large shrub: Excellent backdrop for lower-growing plants like Cleveland sage, lantana, Mexican honeysuckle, pink fairy duster. Can form an informal hedge or screen.

As a small tree: Perfect for patios or courtyards. Anchor a planting bed or flank an entry surrounded by drought-tolerant perennials such as angelita daisy, autumn sage, desert marigold, Mexican bush sage, and Parry’s penstemon.

Planting Notes

Plant in well-drained soil in full sun or filtered shade, avoiding western exposure. Protect from high winds—branches are somewhat brittle. Minimal pruning needed; no fertilizer required. Drought-tolerant but handles ample water if soil is well-drained.
