| Botanical Name | Catharanthus roseus |
| Description | Vinca is a champion of the Houston summer, standing up to triple-digit heat and high humidity better than almost any other annual. In hanging baskets, trailing varieties provide a lush, overflowing look. While they are very drought-tolerant, they require well-draining potting media; avoid overwatering or allowing the basket to sit in heavy, saturated clay soil, which can lead to root rot. |
| Exposure | Full Sun (at least 6+ hours) |
| Height x Width | 8-14 in. Tall x 15-20 in. Spread (Trailing) |
| Water | Low to Moderate; allow the top inch of soil to dry out between waterings. Highly sensitive to overwatering. |
| Zones | 9 - 11 (Annual in Houston) |
| Fertilization | Apply a water-soluble bloom-boosting fertilizer every 2 weeks for continuous flowering. |
| Pruning | Minimal; self-cleaning (no deadheading required). Pinch back stems if they become too leggy. |
| Deer Resistance | High |
