As the Regional Account Manager for PanAmerican Seed in the southwest region of the United States, I’ve grown a knowledge for what kinds of plants work and thrive in this corner of the country.
As we continue to see record high temps during the summer season, here are some insights into drought-tolerant plants.
1. What makes a good drought-tolerant plant? Drought tolerant plants are ones that can handle periods on little to no water and maintain their ability to survive. Some drought tolerant plants will continue to grow in drought conditions (think cactus) while others will go dormant and revive when they receive water.
2. Does it depend on regionality? Yes definitely. Soil type, heat, humidity and other environmental factors play a role. For high heat and extremely low water (desert conditions) cactus and succulents are good drought-tolerant options. In other areas, items like Lantana, Salvia, Interspecific impatiens, etc. are drought tolerant.
3. What’s a good tip that gardeners should know? The biggest issue I typically see is when drought-tolerant plants are planted with more water-loving plants. They tend to get overwatered easily in this situation.
4. Name a few favorite drought-tolerant plants? Lantana, Echinacea, several species of Salvia (Salvia Lancelot is my favorite), Rosemary, Lavender, Perovskia, Buddleia, Bouganivillea, Adenium, Achillea, Interspecfic Impatiens Solarscape
5. Recommendations on what other plants to pair with drought-tolerant plants? There are many shrubs that can pair with drought-tolerant plants, such as: Abelia, Yaupon Holly, Barberry and many others. Also, annuals such as Purslane, Portulaca, Vinca, and Angelonia would be a successful pairing.
