The best xeriscaping plants are the ones suited to your local climate, soil, sunlight, and water supply—not a universal list of “drought-tolerant” favorites. Choose plants for the job they need to do, check their mature size and local suitability, and group them by similar water needs. Utah State University Extension’s regional examples are useful illustrations, but they are not a planting prescription for every climate.
What makes a plant a good choice for xeriscaping?
A plant can tolerate drought and still be a poor fit for a particular yard. Cold winters, hot summers, soil texture and drainage, exposure to sun or shade, and available irrigation all affect whether it will thrive. Utah State University Extension sums up the principle: “Selecting the right plant for the right place is essential for creating a water-efficient landscape.” Its water-wise landscaping guidance treats plant selection as one part of planning the whole landscape.
Start by matching plants to actual site conditions. Then consider the landscape role: shade tree, screen, groundcover, erosion control, seasonal flowers, foliage, or habitat. Check the plant’s mature height, spread, and form against the space so it can grow without crowding paths, buildings, or other plants.
Which xeriscaping plants should you consider?
There is no nationally applicable ranking of the best plants. Regional lists are more useful because they can account for local winters, soils, and growing conditions. Utah State University Extension’s Water-Wise Plants for Utah Landscapes was developed with university, water-conservation, government, botanical-garden, nursery, and native-plant partners. Its criteria include adaptation to Utah’s arid climate and cold winters, water conservation, availability, maintenance, and landscape qualities.

- Pollinator Magnet: Scarlet sage salvia seeds burst into spikes that draw hummingbirds and bees. Ideal wildflower seeds for pollinator seed mix borders in USDA zones 2–12 and sunny beds.
- Easy to Sow: These sage seeds need light, so surface sow sage seeds for planting without covering in late fall directly. For spring: chill 30 days before planting, germination occurs in 1–2 weeks at 65–75°F.
- Heat & Drought Tough: Red sage salvia perennial plantings handle heat, sandy or rocky soil, and low water. Use these garden seeds in wildflower mix borders for lasting color & 18 inches tall flowers.
- Versatile & Beautiful: Sage flowers on salvia plants glow scarlet in late summer and early fall. Flower seeds for planting that give deer resistant spikes for hummingbird gardens and bright bouquets.
- High-Value Seed Packets: 1000 sage salvia seeds for planting outdoors, non gmo seeds that self-seed. Ideal heirloom flower seeds for the plant salvia in borders and meadow-style plantings.
Examples for sandy soils in Utah
For Utah gardeners with sandy soils, USU Extension identifies Utah agave (Agave utahensis), Apache plume (Fallugia paradoxa), singleleaf ash (Fraxinus anomala), and fernbush (Chamaebatiaria millefolium) as examples to consider. Several are also identified as drought tolerant. These are regional examples: their inclusion does not establish that they are suitable for other climates or every sandy-soil site. See USU’s guidance on gardening in sandy soils and verify local conditions before planting.
Find a list for your own region
If you live outside Utah, begin with your state or local university Extension, water utility or conservation garden, and regional native-plant organization. USU’s plant-list page points readers toward databases and lists that can be filtered by region and desired characteristics.

- SUMMER FLOWERS: Produces classic purple blooms with a strong, soothing lavender scent.
- GROWTH: Reaches about 12 inches tall and wide with a compact, mounded habit.
- CARE: Thrives in full sun with excellent drainage and low water once established.
- FUN FACT: Lavender attracts pollinators while naturally deterring deer.
- LIVE PLANTS: Our plants are grown exclusively for Deep Roots and The Three Company, shipped fresh directly from our greenhouse to you!
How should you compare plant candidates?
Use more than a drought-tolerance label when deciding between plants. Check each candidate against the conditions and purpose of the planting area.
- Climate: Confirm suitability for local temperatures and winter cold.
- Soil: Match soil texture and drainage; a plant suited to sandy soil may not suit a site that stays wet.
- Light: Check whether the location is sunny, partly shaded, or shaded.
- Size and form: Compare mature height and spread with the available space.
- Water: Identify the plant’s water needs and the irrigation group it belongs in.
- Purpose and interest: Consider screening, shade, groundcover, erosion control, blooms, foliage, and habitat.
- Maintenance and risk: Check upkeep requirements, invasive potential, and whether a cultivar has different hardiness or drought traits from its parent species.
Native plants can be well adapted to local conditions, but a water-wise landscape does not have to consist entirely of native species. Plants from other dry regions can also be candidates if they suit the site and are not invasive. Confirm a plant’s suitability and cultivar traits with a local source.

How do you plan water needs and irrigation?
Group plants with similar water requirements into hydrozones so each area can be irrigated to suit its plants. A thirstier plant can raise the water needs of the whole zone, while some desert-adapted plants may be harmed by overwatering. USU Extension’s water-wise landscape implementation guidance discusses hydrozones and plant-specific irrigation needs.
Mulch can support the water plan by reducing soil evaporation and weeds, as described in USU’s water-wise landscaping principles. Choose mulch with the plants, watering approach, and intended use of the area in mind. Drip irrigation is one option mentioned in USU’s water-wise gardening guidance, but system design depends on the site and the plants; there is no one-size-fits-all setup.
Rank #4
- Native Ornamental grass seeds drought tolerant Xeriscape landscaping
Do not assume a new planting needs no supplemental water. USU’s implementation guidance notes that established native plants often need supplemental irrigation mainly during extreme drought, while emphasizing hydrozones and individual plant needs. Establishment and ongoing watering should be planned for the plants and conditions at your site.
How do you avoid common selection mistakes?
- Do not apply a regional list everywhere. A Utah recommendation does not establish suitability for another region; use a local list as your starting point.
- Do not choose by drought tolerance alone. Check soil, drainage, light, cold hardiness, mature size, and intended role.
- Do not mix very different water needs in one zone. Otherwise, irrigation suited to one plant may leave another thirsty or overwatered.
- Do not assume native means maintenance-free. Establishment and extreme drought can still require supplemental irrigation.
- Do not skip invasive-risk checks. Verify local guidance before planting an introduced species, and confirm that a cultivar retains the traits you need.
The available extension guidance provides practical regional advice, not a single national plant ranking or a quantified water-savings figure. Choose from locally relevant lists and plan for the conditions in your landscape.
