| Botanical Name | Artemisia 'Powis Castle' |
| Description | A legendary woody-based perennial for Willis and Houston, 'Powis Castle' is prized for its soft, billowy mounds of silver foliage. It provides a stunning visual break between colorful flowering plants. While many Artemisias struggle with the Texas humidity, 'Powis Castle' is one of the most resilient. To ensure it thrives in our local clay, it must be planted in a raised bed or a very well-drained sunny spot; good airflow and "dry feet" are essential to keeping this plant beautiful through a wet Southeast Texas winter. |
| Exposure | Full Sun (Required to keep the silver color intense and the habit tight) |
| Height x Width | 2-3 ft. Tall x 2-3 ft. Wide |
| Water | Low. Very drought-tolerant once established. Overwatering is the most common cause of failure in the Houston area. |
| Zones | 6 - 9 (Reliable evergreen perennial in Southeast Texas) |
| Fertilization | Generally not required. If growth is poor, apply a very light amount of balanced, slow-release fertilizer in early spring. |
| Pruning | Trim lightly in spring to maintain its rounded shape. Avoid cutting back into the old, woody stems in late fall, as this can weaken the plant before winter. |
| Deer Resistance | High (The bitter taste and strong fragrance are very effective deterrents) |
