The Truth About Xeriscape: It’s Not Just Rocks and Cactus
For many homeowners, the mention of “xeriscape” conjures up images of dull, lifeless landscapes dominated by rocks and the occasional cactus. However, this narrow perception couldn’t be further from the truth. Xeriscape, when done right, is a sustainable landscaping approach that can provide a visually stunning and ecologically beneficial outdoor oasis.
The term “xeriscape” was coined in Colorado by Denver Water to encompass water-conserving landscape designs. “Xeric” means “dry,” but xeriscape is not synonymous with a zero-maintenance, desert-style landscape. In fact, a well-designed xeriscape can be lush, vibrant, and teeming with life.
“Xeriscape is not rock and cactus,” explained Alison Peck, a sustainable landscaping designer and contractor with Boulder’s Matrix Gardens. “This is a grassland, not a desert. There’s a huge number of crucial benefits that sustainable landscapes provide, and it doesn’t take that much more attention to make them much more beneficial to us and the world around us.”
Cultivating Ecological Abundance
At the heart of a successful xeriscape lies an understanding of the local ecosystem and a commitment to working in harmony with nature. Rather than forcing a one-size-fits-all approach, the key is to select plants and design elements that thrive in the regional climate and soil conditions.
“Sustainable landscapes can range from a low-water landscape providing wildlife habitat, to a high-water landscape that sequesters large amounts of carbon and provides an abundance of food,” said Peck. “The goal is to balance the resources used — water, energy and time — with the benefits created — food, habitat, carbon sequestered and happy, healthy people.”
Promoting Biodiversity and Carbon Sequestration
One of the primary advantages of xeriscape is its potential to support biodiversity and enhance carbon sequestration. By incorporating native plants and grasses, a xeriscape can provide vital habitats and food sources for local wildlife, from pollinating insects to birds and small mammals.
“Ninety percent of all birds depend on insects to raise their young,” Peck explained. “This means that the insects in your yard are a resource, not a problem. Native plants are homes for native insects, and native insects are the crucial base for the food pyramid.”
Beyond supporting wildlife, a well-designed xeriscape can also help mitigate climate change through carbon sequestration — the long-term storage of carbon in the soil and vegetation. “There’s too much carbon in the atmosphere and not enough in the soil,” Peck said. “Encourage plants to have a big, deep root system. Water them so you water deeply, which encourages roots to grow deeply. Water less frequently but water longer.”
Reducing Water Consumption and Maintenance Needs
One of the primary goals of xeriscape is to reduce water consumption, making it an increasingly attractive option in regions facing water scarcity. By strategically selecting drought-tolerant plants and incorporating water-efficient irrigation systems, a xeriscape can significantly lower household water usage.
“For a lawn that will be frequently used year-round, bluegrass is usually the best choice,” Peck said. “But it’s a high water-use plant, so carefully consider how big of an area you want.” Alternatives like turf-type tall fescue, buffalo grass, and blue grama grass can provide a lawn-like appearance while requiring far less water.
Moreover, a xeriscape often requires less ongoing maintenance compared to a traditional lawn-based landscape. With the right plant selection and design, a xeriscape can minimize the need for mowing, fertilizing, and other time-consuming tasks.
Designing a Tailored Xeriscape
When it comes to creating a xeriscape, there is no one-size-fits-all approach. The key is to start by assessing your goals and priorities, whether that’s water conservation, food production, wildlife habitat, or a combination of these.
“Homeowners should determine what their goal is first,” Peck advised. “Are you trying to conserve water or energy? Do you want to grow food in your yard? Do you want to attract wildlife? What does sustainability mean to you?”
Once you have a clear vision, you can begin to select the right mix of plants, hardscaping elements, and irrigation systems to bring your xeriscape to life. Remember, a successful xeriscape is not just about replacing grass with rocks or cactus; it’s about creating a thriving, diverse, and environmentally-friendly landscape that meets your unique needs and preferences.
Incorporating Native Plants and Drought-Tolerant Species
At the heart of any xeriscape is a focus on native and drought-tolerant plants. These species are uniquely adapted to the local climate and soil conditions, requiring less water and maintenance while providing valuable habitats for local wildlife.
“Native plants are your best friend if you want to create a habitat for wildlife,” Peck said. “Native plants are homes for native insects, and native insects are the crucial base for the food pyramid.”
Some of Peck’s top recommendations for xeriscape-friendly plants include:
- Lydia Broom
- Autumn Amber Sumac
- Gumball Spirea
- Broadmoor and Blue Chip Junipers
- Dwarf Blue Rabbitbrush
- Pawnee Buttes Sand Cherry
These plants not only thrive in drier conditions but also offer visual interest through their foliage, flowers, and seasonal changes. By incorporating a diverse mix of native and drought-tolerant species, you can create a xeriscape that is both beautiful and ecologically beneficial.
Optimizing Irrigation and Soil Health
While reducing water consumption is a key goal of xeriscape, it’s important to ensure that the plants receive the moisture they need to thrive. Implementing efficient irrigation systems, such as drip irrigation or soaker hoses, can deliver water directly to the roots without excessive evaporation or runoff.
“Emitter tubing is a high-tech, efficient, and affordable choice for watering raised bed or in-ground gardens,” said Peck. “Research has shown that soil capillary action transports water horizontally as well as vertically, so water from each emitter will spread across the bed toward the water from other emitters.”
In addition to efficient irrigation, maintaining healthy, nutrient-rich soil is crucial for a thriving xeriscape. By incorporating compost, mineral-rich amendments, and other organic materials, you can create a vibrant growing medium that supports robust plant growth and a diverse soil food web.
“Don’t feed the plants. Feed the soil so it can feed the plants,” Peck advised. “A healthy soil food web is busy with billions of microscopic organisms as well as larger creatures, like earthworms, all working together. Healthy soil promotes the processes of nutrient development and delivery (to plants).”
Embracing the Xeriscape Lifestyle
Embracing a xeriscape lifestyle isn’t just about creating a water-wise landscape; it’s about cultivating a deep connection with the natural world and finding joy in the process.
“Xeriscape is not ‘Zero-scape,’” Peck emphasized. “There are many beautiful alternatives to a traditional lawn, from native prairie grass with wildflowers to xeric perennial flowers, grasses, shrubs, and trees. Your landscape can be designed to fit you, what you like to do outside, your budget, and your schedule.”
By thoughtfully designing and maintaining a xeriscape, you can not only reduce your environmental impact but also foster a thriving, biodiverse oasis that provides year-round beauty, habitat, and a sense of harmony with the local ecosystem.
“We have created water-conserving Victorian gardens, native landscapes that require no water once established, and modern landscapes that combine very low water and maintenance areas with abundant oases that provide food for people and wildlife,” Peck said. “The possibilities are endless when you approach xeriscape with a focus on sustainability and ecological balance.”
So, forget the outdated stereotypes of xeriscape as a dull, lifeless landscape; this sustainable approach to landscaping offers a world of possibilities for creating a beautiful, vibrant, and environmentally-conscious outdoor space that meets your unique needs and preferences.
