Hi there, Dave Fox from Foxy Gardens here. When you walk past a beautifully maintained corporate campus, hospital, hotel, or business park, you might not think about who actually decided which trees, shrubs, and flowers belong there.
But behind the scenes, there’s a team of professionals — each with unique skills — that work together to create outdoor spaces that are functional, attractive, and sustainable.
If your business is considering a landscaping overhaul or is building a new property, understanding who designs and chooses the plants is the first step toward a space that’s both beautiful and practical.
Below, we’ll explore the key roles in commercial landscaping, what each one does, and how to know which expert your project needs.
Landscape Architects
Scope:
Landscape architects are the “big picture” designers of outdoor spaces. They don’t just choose plants — they plan how the entire property will look and function. This can include pathways, retaining walls, water features, seating areas, lighting, and irrigation systems.
Training & Credentials:
-
Typically hold a degree in Landscape Architecture.
-
Licensed professionals (in Ontario, through the Ontario Association of Landscape Architects).
What They Do in Plant Selection:
Landscape architects often choose plant palettes that:
-
Fit the climate zone (Ontario has Zones 3–6 depending on the region).
-
Provide seasonal interest year-round.
-
Work within maintenance budgets.
When to Hire One:
If you’re building a large commercial development, planning a corporate headquarters, or overhauling a high-visibility public space, a landscape architect can bring structure, creativity, and compliance with municipal bylaws.
Landscape Designers
Scope:
Landscape designers focus more heavily on plants, garden beds, and decorative arrangements than on structural elements. They blend aesthetics and practicality, ensuring your corporate grounds have visual appeal and harmony.
Training & Credentials:
-
May have diplomas in horticulture or design.
-
Not typically licensed like architects, but often highly experienced in plant combinations and soil compatibility.
What They Do in Plant Selection:
-
Choose plants based on colour schemes, texture, bloom times, and how they’ll look together.
-
Factor in maintenance requirements so the design stays fresh without constant upkeep.
-
Select plants that reflect the brand identity of the business — for example, a spa might have calming ornamental grasses, while a tech company might prefer bold, modern arrangements.
When to Hire One:
If your project is plant-focused and you want a professional eye for colour, seasonality, and long-term appearance, a landscape designer is your go-to.
Horticultural Consultants
Scope:
A horticultural consultant is the plant scientist of the group — the person who knows why a certain shrub might fail in your soil or why a particular tree is susceptible to pests in your area.
Training & Credentials:
-
Often hold degrees in plant science, botany, or horticulture.
-
Many have years of practical experience in plant care and propagation.
What They Do in Plant Selection:
-
Ensure that chosen plants are compatible with soil type, pH, and drainage.
-
Recommend native species for biodiversity and pollinator support.
-
Prevent costly mistakes like planting invasive species or high-maintenance plants in the wrong location.
When to Hire One:
If your property has tricky soil conditions, drainage issues, or if you’re aiming for eco-friendly, low-maintenance landscaping, a horticultural consultant is a smart choice.
Arborists
Scope:
Arborists specialize in trees — their health, safety, and placement. On large properties, trees are often the most valuable landscaping asset, and mistakes in planting can be expensive and long-lasting.
Training & Credentials:
-
Certified through the International Society of Arboriculture (ISA).
-
Trained in tree biology, pruning, disease prevention, and safe removal techniques.
What They Do in Plant Selection:
-
Choose tree species suited to local climate and soil.
-
Advise on root growth patterns to avoid damaging sidewalks or underground utilities.
-
Ensure trees won’t block signage, lighting, or building sightlines.
When to Hire One:
If your commercial landscaping plan involves trees — whether shade trees, ornamental species, or windbreaks — an arborist can protect your investment.
Corporate Grounds Managers
Scope:
Once the landscape is installed, someone needs to keep it looking its best. Corporate grounds managers (or contracted landscaping crews) maintain lawns, prune shrubs, plant seasonal flowers, and address problems as they arise.
Training & Credentials:
-
Often experienced landscapers or horticulturists.
-
Some have turf management or groundskeeping certifications.
What They Do in Plant Selection:
While they may not create the initial design, grounds managers can advise on replacement plants, seasonal changes, and ongoing improvements based on practical experience.
When to Hire One:
If you want your landscaping to remain healthy and attractive for years, a dedicated grounds manager or long-term landscaping contract is essential.
Plant Stylists & Exterior Plant Consultants
Scope:
While more common in interior design, plant stylists and exterior plant consultants are emerging in the commercial space. They focus on the look and feel of plant arrangements, sometimes collaborating with marketing teams to match a brand’s personality.
Training & Credentials:
-
Often self-taught or design-school trained with a passion for plants.
-
May have horticulture knowledge but are more focused on aesthetics.
What They Do in Plant Selection:
-
Suggest plants that fit a specific theme or seasonal event.
-
Curate unique combinations for patios, entryways, or lobbies.
-
Provide temporary or rotating displays for holidays and promotions.
When to Hire One:
If your company wants seasonal, eye-catching plant arrangements — especially near entrances or high-traffic areas — a plant stylist can make a big difference.
How These Roles Work Together
In many large projects, these roles overlap:
-
A landscape architect creates the master plan.
-
A landscape designer refines the planting layout.
-
A horticultural consultant ensures plant compatibility.
-
An arborist oversees tree health and placement.
-
A grounds manager keeps it all thriving year after year.
Choosing the right combination depends on your property size, goals, and budget.
Factors Influencing Plant Choice in Commercial Landscaping
-
Climate Zone: Ontario spans several plant hardiness zones, from 3 in the north to 6 in the southern regions.
-
Soil Type: Sandy soils drain quickly but may require drought-tolerant plants, while clay soils hold water and may need plants with strong root systems.
-
Maintenance Budget: Low-maintenance native plants can save money long-term.
-
Branding Needs: Certain plants can communicate luxury, sustainability, or tradition.
-
Regulations: Municipalities may require native plant use or ban invasive species.
Final Thoughts
Commercial landscaping is more than just “planting pretty flowers.” It’s a strategic combination of science, design, and maintenance. The professionals you choose will determine how your outdoor spaces look, function, and age over time.
By understanding the roles — from landscape architects to horticultural consultants — you’ll be better equipped to hire the right experts, avoid costly mistakes, and create a property that makes a lasting impression.
