Editor's Note: In the second part of our series on Thriving Plants In Extreme Heat, Sam Page of PLANT THIS Palm Springs answers your questions about the best heat-resistant plants, including native and non-native options, and how to group them for minimal water usage in extreme heat.
Q: What are the best heat-resistant plants for extreme climates?
Some of the best heat-resistant plants for hot climates include:
- Agave – Drought-resistant, stores water in its thick leaves.
- Yucca – Tolerates intense heat and poor soil conditions.
- Lantana (Lantana camara) – Heat and drought-resistant with vibrant, pollinator-friendly flowers.
- Desert Marigold (Baileya multiradiata) – Thrives in extreme heat and dry soil with bright yellow blooms.
- Red Yucca (Hesperaloe parviflora) – Handles heat and drought, attracting hummingbirds.
- Palo Verde Tree (Parkinsonia) – Deep roots that access underground water and thrive in arid conditions.
Q: Should I choose native or non-native plants for my heat-resistant garden?
Native Plants: These are adapted to the local climate and need less maintenance, requiring minimal water. They support local ecosystems and attract beneficial insects. Examples include cacti, desert wildflowers, and native shrubs.
Non-Native Plants: Some non-natives, like Mediterranean herbs and drought-resistant succulents, can thrive in hot climates if they’re well-suited to your region's conditions.
Q: Why are native plants a smart choice for a heat-resilient garden?
A: Native plants are adapted to local climates, requiring less water and maintenance. They help conserve resources and provide habitats for local wildlife, including pollinators and beneficial insects.
Q: How can I use companion planting for moisture retention in a heat-resistant garden?
A: Companion planting helps reduce water waste and retain moisture. Here’s how:
- Shallow-rooted plants (like creeping thyme) provide soil shade to reduce evaporation.
- Tall, hardy plants (like desert trees) can provide shade to smaller, delicate plants.
- Mulch helps prevent water loss and maintains stable soil temperatures.
Q: How should I group plants based on their water needs?
A: Group plants that share similar water needs to avoid wasting water and improve efficiency. Here are some tips:
- Identify plant water requirements: Place drought-tolerant plants together and keep those needing occasional watering in separate areas.
- Use microclimates: Plant water-loving species in shaded, cooler spots.
- Leverage companion planting: Pair plants that help each other’s growth and moisture retention.
Q: How can I ensure my plants thrive in extreme heat?
A: Start by selecting the right plants, focusing on heat-resistant, drought-tolerant varieties. Group them strategically for efficient water usage and moisture retention.
Our next Q&A will focus on soil preparation and water management strategies to further optimize your garden’s health in extreme heat.
