Xeriscaping has gained attention as water restrictions become more common and gardeners seek sustainable landscaping solutions. Yet despite its growing popularity, xeriscaping remains one of the most misunderstood concepts in modern gardening. Many people envision barren landscapes filled with rocks and cacti, devoid of colour or life. This couldn’t be further from the truth. Let’s separate fact from fiction and explore what xeriscaping really means for Australian gardens.
Myth 1: Xeriscaping Means a Desert of Rocks and Gravel
Perhaps the most persistent myth about xeriscaping is that it results in stark, lifeless landscapes dominated by gravel and boulders. This misconception likely stems from poorly executed “zero-scaping” where homeowners simply cover their yards with rocks and call it done.
True xeriscaping celebrates plants and creates lush, vibrant gardens that happen to use less water. The term comes from the Greek word “xeros” meaning dry, combined with landscaping. It’s about intelligent plant selection and design, not plant elimination. Well-designed xeriscape gardens can be incredibly diverse, featuring flowing grasses, colourful flowering perennials, and even small trees. The key is choosing plants adapted to your local climate rather than forcing thirsty exotic species to survive.
Many stunning drought-tolerant plants offer spectacular displays. Think of the silver-blue foliage of Teucrium fruticans, the vibrant purple spikes of Salvia ‘May Night’, or the architectural beauty of Agave attenuata. These plants create rich tapestries of colour and texture while thriving on minimal water.
Myth 2: You Can Only Use Cacti and Succulents
While cacti and succulents certainly have their place in water-wise gardens, limiting yourself to these plants unnecessarily restricts your design options. Xeriscaping encompasses a vast array of plant choices from Mediterranean herbs to Australian natives, ornamental grasses to flowering shrubs.
Consider lavender’s fragrant purple blooms, the delicate flowers of Gaura lindheimeri dancing in the breeze, or the bold architectural statements made by grass trees (Xanthorrhoea species). Native plants like grevilleas, westringias, and correas provide year-round interest with minimal water requirements. Many traditional cottage garden plants, including rosemary, sage, and yarrow, are naturally drought-tolerant once established.
The secret lies in understanding your local climate and choosing plants that naturally thrive in those conditions. In Mediterranean climates, this might include olive trees and rock roses. In more temperate areas, native grasses and adapted perennials work beautifully. The palette is limited only by your climate zone, not by the xeriscaping concept itself.
Myth 3: Xeriscaped Gardens Are High Maintenance
Contrary to popular belief, properly designed xeriscaped gardens require significantly less maintenance than traditional landscapes. The myth of high maintenance often arises from poorly planned gardens where inappropriate plants struggle to survive, or where the initial establishment phase is confused with ongoing care requirements.
Once established, drought-tolerant plants need minimal intervention. They’ve evolved to thrive without constant human attention. No weekly mowing of thirsty lawns, no daily watering during summer, and no regular fertilising of hungry exotic plants. Native and adapted plants resist local pests and diseases better than imports, reducing the need for chemical interventions.
The key to low maintenance lies in proper plant selection and placement. Group plants with similar water needs together, use mulch to suppress weeds and retain moisture, and allow plants to grow into their natural forms rather than constantly pruning them into unnatural shapes. The result is a garden that largely takes care of itself, freeing you to enjoy rather than constantly tend your outdoor space.
Myth 4: Low-Water Gardens Look Dead in Summer
This myth persists because people assume drought-tolerant means dormant during dry periods. While some plants do employ summer dormancy as a survival strategy, many xerophytic plants look their absolute best during the hottest months when traditional gardens struggle.
Summer-blooming salvias explode with colour just as lawns turn brown. Ornamental grasses like Miscanthus and Pennisetum reach their full glory in summer heat. Mediterranean plants such as cistus and teucrium often flower most prolifically during warm, dry weather. Australian natives like bottlebrush and tea trees save their spectacular displays for when rainfall is scarce.
Smart design ensures year-round interest by combining plants with different blooming seasons and foliage textures. Silver-leaved plants like Artemisia and Senecio provide cooling contrast during hot months, while the seed heads of grasses and dried flowers add architectural interest. Far from looking dead, well-planned xeriscaped gardens offer dynamic displays that change with the seasons.
Myth 5: Xeriscaping Means No Lawn
While reducing or eliminating traditional lawn areas can significantly decrease water usage, xeriscaping doesn’t mandate a lawn-free landscape. The principle focuses on using turf grass wisely rather than eliminating it entirely. If you love lawn for children’s play areas or picnics, include it – just be strategic about how much and where.
Consider limiting lawn to functional areas where it’s actually used, rather than growing it by default. Replace unused lawn areas with groundcovers, mulched beds, or hardscaping. When you do include turf, choose drought-tolerant species like Buffalo grass or native Microlaena, which require far less water than traditional couch or kikuyu varieties.
Alternative “lawns” made from native groundcovers like Dichondra repens (kidney weed) or Zoysia tenuifolia (no-mow grass) provide green coverage with minimal water requirements. These living carpets offer the visual appeal of lawn without the high water and maintenance demands.
Myth 6: Xeriscaping Is Expensive to Install
The initial cost of xeriscaping often concerns homeowners, but this viewpoint fails to consider long-term savings. While establishing any new garden requires investment, xeriscaped gardens typically cost no more than traditional landscapes to install and far less to maintain over time.
Consider the ongoing costs of maintaining a traditional garden: water bills, fertilizers, pesticides, lawn mower fuel, and potentially hiring maintenance help. Xeriscaped gardens dramatically reduce or eliminate these expenses. Many councils offer rebates for lawn removal or installing water-wise gardens, offsetting initial costs.
Start small if budget is a concern. Convert one area at a time, beginning with the most challenging spots where traditional plants struggle. Use division and cuttings from established plants to expand your garden economically. Many drought-tolerant plants, particularly succulents and native grasses, propagate easily from cuttings or division.
Myth 7: Drought-Tolerant Plants Are Ugly
This myth reveals a lack of familiarity with the incredible diversity of water-wise plants available. From the architectural drama of agaves to the cottage garden charm of lavender, drought-tolerant plants offer every aesthetic imaginable. The stunning flowers of kangaroo paws, the ethereal beauty of Mexican sage, and the sculptural forms of grass trees rival any thirsty exotic for visual impact.
Modern plant breeding has produced exceptional drought-tolerant varieties with extended flowering periods, compact growth habits, and spectacular colours. Grevillea ‘Superb’ offers enormous orange and yellow flowers, while Echinacea breeding has produced drought-tolerant coneflowers in every shade from white to deep burgundy.
The key is designing with the same principles used in any beautiful garden: considering form, texture, colour, and seasonal interest. A well-designed xeriscape garden can be formal or casual, modern or traditional, subtle or bold – the plant palette supports any design vision.
Creating Your Own Water-Wise Paradise
Understanding what xeriscaping truly means opens up exciting possibilities for creating beautiful, sustainable gardens. Start by observing your site’s conditions: sun exposure, soil type, and natural water flow. Choose plants that match these conditions rather than fighting against them.
Design for both aesthetics and function, creating outdoor rooms that invite use while minimising water consumption. Include hardscaping elements like paths and patios that reduce planted areas while increasing usability. Harvest rainwater where possible, direct runoff to planted areas, and use mulch generously to retain soil moisture.
Remember that xeriscaping is a set of principles, not a rigid prescription. Adapt these concepts to your lifestyle, aesthetic preferences, and local conditions. The result will be a garden that’s not only beautiful and sustainable but also uniquely yours – proving that water-wise landscaping enhances rather than limits your gardening possibilities.
