| Botanical Name | Oxalis regnellii 'Ebony Allure' |
| Description | 'Ebony Allure' is prized in the Houston metro area for its nearly jet-black, trifoliate leaves and dainty contrasting flowers. While it loves the high humidity of Southeast Texas, it is highly sensitive to soil drainage. In our local landscapes, it can struggle in heavy, unamended clay which stays saturated too long. It performs best in a loose, organic-rich soil or a high-quality potting mix. It may go semi-dormant during the most extreme summer heat but will bounce back as temperatures moderate. |
| Exposure | Part Sun to Part Shade (Protect from harsh afternoon sun) |
| Height x Width | 8-12 in. Tall x 10-15 in. Wide |
| Water | Medium; keep soil consistently moist but never soggy. Allow the top inch of soil to dry before watering. |
| Zones | 7 - 10 |
| Fertilization | Use a balanced, water-soluble fertilizer at half-strength every 4-6 weeks during the growing season. |
| Pruning | Remove spent blooms or any yellowing foliage to keep the clump looking tidy. |
| Deer Resistance | Moderate (Oxalic acid in leaves often deters light browsing) |
