| Botanical Name | Citrus sinensis 'Republic of Texas' |
| Description | The 'Republic of Texas' Orange is a true survivor and a piece of Texas history. This 3-gallon (3G) tree is an heirloom variety known for being one of the most cold-hardy sweet oranges available for the Willis and Houston area. It produces medium-to-large fruits with a slightly bumpy rind and an old-fashioned, rich orange flavor that modern supermarket varieties often lack. The tree is famously thorny, which is a characteristic of its robust, wilder heritage, but the reward is a heavy crop of juicy, sweet fruit that ripens in late fall. Because Southeast Texas can still face extreme winter events, you must protect from freeze (especially the graft) to ensure the tree reaches its full potential. Its glossy evergreen leaves and fragrant blossoms make it a hardy and historical addition to any Texas garden. |
| Exposure | Full Sun (Essential for fruit sugar development and overall health) |
| Height x Width | 10-15' Height x 8-12' Width |
| Water | Moderate; requires consistent moisture during the growing season. Ensure excellent drainage, particularly in the heavy clay soils of the Houston region, to prevent root rot. |
| Zones | 8b - 11 (One of the hardiest oranges, often surviving dips into the low 20s once established) |
| Fertilization | Apply a specialized citrus fertilizer three times per year: late winter (Feb), late spring (May), and late summer (Aug/Sept). |
| Pruning | Minimal; remove suckers growing below the graft line. Exercise caution due to thorns when pruning for shape or removing dead wood in early spring. |
| Deer Resistance | Moderate |
