| Botanical Name | Stachytarpheta jamaicensis |
| Description | Blue Porterweed is an essential addition to any Houston butterfly garden, known for its unique "rattail" flower spikes. It is incredibly well-suited to the humidity of the Gulf Coast and handles summer heat without fading. While it is adaptable to various soil types, it requires consistent moisture to look its best. In areas with heavy clay, ensure the soil is amended with organic matter to prevent the roots from sitting in stagnant, anaerobic water during our frequent heavy rain events. |
| Exposure | Full Sun to Part Shade (Best flowering occurs in Full Sun) |
| Height x Width | 3-4 ft. Tall x 3-4 ft. Wide |
| Water | Medium; prefers regular watering but can handle short periods of drought once established. |
| Zones | 9 - 11 (Often grown as a reseeding annual or protected during winter freezes) |
| Fertilization | Use a balanced, slow-release fertilizer in early spring and again in mid-summer. |
| Pruning | Lightly prune the tips occasionally to encourage a bushier habit and more flower spikes. |
| Deer Resistance | Moderate |
