How to Choose Landscape Plants That Perform Better: Why Plant Genetics Matter

Better Plant Selection Starts with Better Genetics

Choosing landscape plants that perform better begins with understanding plant genetics. Landscape architects and designers make decisions that influence maintenance costs, water use, public safety, and landscape performance for decades. While irrigation, soil preparation, and installation all contribute to success, the genetic characteristics of a plant often determine whether it will achieve the original design intent.

Every plant specified for a commercial landscape is a long-term investment. Understanding how genetics influences plant performance helps professionals create landscapes that remain attractive, resilient, and easier to maintain throughout their lifespan.

Why Landscape Architects Should Care About Plant Genetics

Landscape architects rarely specify plants based on appearance alone.

Every plant selection must satisfy multiple project requirements, including:

• Long-term performance

• Water conservation goals

• Maintenance budgets

• Public safety

• Mature size

• Design consistency

• Climate adaptability

Plant genetics influences each of these factors.

While two plants may belong to the same species, they can perform very differently depending on the traits they inherit. Improved cultivars are often selected because they consistently solve problems that landscape professionals encounter every day.

For designers responsible for commercial developments, parks, streetscapes, HOA communities, healthcare campuses, and municipal projects, those differences matter.

What Plant Genetics Actually Influence

Plant genetics determines many of the characteristics that affect landscape performance over time.

These include:

• Mature height and spread

• Growth habit

• Branching structure

• Flower production

• Bloom duration

• Heat tolerance

• Drought tolerance

• Cold hardiness

• Seed production

• Thorn production

• Overall uniformity

These inherited traits help determine whether a plant will continue to meet design expectations years after installation.

Five Questions to Ask Before Specifying Landscape Plants

1. Is This Plant Adapted to Arizona and Southwest Conditions?

Plants that evolved or were selected for hot, arid climates generally establish more successfully in Arizona landscapes.

Selecting desert-adapted plants, such as Civano Originals, can improve long-term performance while supporting water-wise landscape goals.

2. Does This Selection Have Predictable Genetics?

Landscape architects depend on predictable results.

Improved plant selections are often evaluated because they demonstrate greater consistency in growth habit, mature size, flowering, or other desirable characteristics.

That consistency helps ensure the installed landscape reflects the original design vision.

3. Will This Plant Create Future Maintenance Problems?

Maintenance costs often exceed installation costs over the life of a landscape.

Consider whether the plant may produce:

• Heavy seed pod litter

• Volunteer seedlings

• Excessive pruning

• Thorn hazards

• Structural issues as it matures

Addressing these concerns during plant selection can reduce maintenance demands for years to come.

4. Will the Plant Continue to Perform as the Landscape Matures?

Successful landscapes are designed for the future, not just opening day.

Ask questions such as:

• Will the canopy eventually outgrow the available space?

• Will the mature form maintain the intended design?

• Will maintenance alter the visual character of the landscape?

• Will the plant remain attractive under local climate conditions?

Thinking beyond installation helps preserve the original design intent.

5. Has This Plant Been Selected to Solve a Real Landscape Challenge?

Many improved cultivars exist because they address common problems found in managed landscapes.

Examples include:

• Reduced seed production

• Thornless growth habits

• Improved branching structure

• More compact growth

• Better drought tolerance

• Greater landscape uniformity

These improvements help landscape professionals balance aesthetics with long-term performance.

Genetics in Action

Plant genetics becomes most valuable when they solve real design problems.

For example, the Civano Seedless Chilean Mesquite was selected to retain the shade and drought tolerance that make Chilean mesquite valuable in Arizona landscapes while eliminating seed pods and thorns that can increase maintenance in commercial settings.

Likewise, the Sweet Bubba Seedless Desert Willow offers the colorful blooms and graceful form of traditional desert willow while eliminating seed pods that often require cleanup in parks, streetscapes, HOA communities, and commercial developments. It also attracts pollinators.

These improvements illustrate how thoughtful plant selection can support both design objectives and long-term landscape management.

Common Mistakes Landscape Architects Make When Selecting Plants

Even experienced professionals can encounter challenges when plant performance is evaluated only at installation.

Common mistakes include:

• Selecting plants based primarily on appearance

• Assuming all plants within a species perform the same

• Overlooking mature growth habits

• Ignoring long-term maintenance requirements

• Not considering improved cultivars that solve common landscape challenges

The most successful landscape designs consider how plants will perform years after the project is complete.

FAQ

How do you choose landscape plants that perform better?

Evaluate plants based on climate adaptability, genetics, mature size, maintenance requirements, and documented long-term landscape performance rather than appearance alone.

Why should landscape architects understand plant genetics?

Plant genetics influence growth habit, drought tolerance, flowering, maintenance needs, and other characteristics that determine whether a landscape continues to perform as intended over time.

Are improved plant selections genetically modified?

No. Most improved landscape plants are developed through traditional breeding, careful selection, or naturally occurring mutations rather than genetic modification.

Why do improved cultivars matter in commercial landscapes?

Improved cultivars may provide more predictable growth, reduced maintenance, better drought tolerance, or other characteristics that improve long-term landscape performance.

Thoughtful plant selection begins long before construction starts. By understanding how genetics influences plant performance, landscape architects and designers can specify plants, such as Civano Originals, that better support their design vision while reducing maintenance challenges throughout the life of the project.
