| Botanical Name | Ferocactus spp. |
| Description | A bold architectural perennial for Willis and Houston rock gardens, the Barrel Cactus is prized for its dramatic ribbed structure and colorful spines. This "Texas-tough" plant is designed for maximum water storage, making it incredibly drought-hardy. While it loves the heat and sun, success in our local environment depends entirely on drainage. In the humid, heavy clay of Southeast Texas, it is vital to plant in a raised bed with a specialized sandy/gritty cactus mix to prevent rot during our frequent rainy periods. |
| Exposure | Full Sun (Essential for proper growth and spine development) |
| Height x Width | 2-4 ft. Tall x 1-2 ft. Wide (Slow-growing) |
| Water | Very Low. Only water during extended dry spells in summer. Must have impeccable drainage; avoid watering entirely during cold, damp winter months. |
| Zones | 9 - 11 (May need protection from hard freezes in the Willis area) |
| Fertilization | Rarely needed. A light application of a specialized cactus fertilizer in late spring can support health in container-grown plants. |
| Pruning | None required. |
| Deer Resistance | High (The formidable spines make it practically deer-proof) |
