For the past several months, I’ve had customers calling the nursery asking for all sorts of unusual plants—many I’ve never even heard of, and certainly not ones that are available or well-suited to our area. After 35+ years in the nursery business, I’m familiar with most of the plants that grow successfully in our climate, so these requests caught me by surprise.
Finally, I asked one customer, “Where did you find out about this plant?”
She smiled and replied, “I used ChatGPT to design my landscape.”
Suddenly, the mystery was solved.
Artificial intelligence has changed the way we dream about our landscapes. With a simple prompt, AI can create stunning garden designs filled with colorful flowers, graceful shrubs, ornamental trees, winding pathways, and inviting outdoor living spaces. The images are beautiful, inspiring, and often spark ideas we may never have considered on our own.
But there’s an important distinction to make.
AI is an incredible landscape illustrator—but it isn’t a horticulturist. It doesn’t spend years watching plants grow, learning which varieties thrive locally, understanding how they mature, or seeing firsthand what works and what doesn’t. That’s the value of experienced gardeners and your local nursery.
A garden isn’t built from pixels. It’s built from living plants.
A landscape design is only as good as the plant knowledge behind it.
Inspiration vs. Reality
AI excels at creating attractive designs, but it doesn’t always account for the realities of gardening in your specific location.
A successful landscape depends on far more than how it looks on the day it’s planted. It requires thoughtful planning based on mature plant size, root systems, climate, soil conditions, sunlight, water requirements, maintenance needs, and—perhaps most importantly—what plants are actually available in your area.
These are things AI may not accurately evaluate when creating a design.
The Availability Problem
One of the first challenges with AI-generated landscape plans is plant availability.
A design may include specialty shrubs, rare trees, or unusual perennials that simply aren’t available at your local garden center. Even if they can be found, they may not perform well in your region or may be difficult and expensive to obtain.
A knowledgeable local nursery can recommend plants that create the same overall effect while being better adapted to your climate and readily available.
Plants Grow
Perhaps the most common oversight is mature plant size.
Young nursery plants are deceiving. A shrub that is only two feet tall today may eventually grow six, eight, or even ten feet wide. Trees become taller and broader. Shrubs expand. Perennials spread.
Landscape designs should be planned for what plants will become—not simply what they look like on planting day.
One of the biggest mistakes homeowners make is planting for today instead of five years from now. A landscape should actually look a little sparse when it’s first installed—and that’s okay. Plants need room to reach their mature size. Crowding them together may create an instant “finished” look, but it often leads to years of excessive pruning, poor air circulation, disease problems, and eventually removing plants that have simply outgrown the space.
Another detail that’s easy to overlook is the difference between cultivars. AI may recommend a Loropetalum, but it doesn’t always specify which one. One variety may mature at only 3 feet tall, while another can easily reach 10 feet or more. Those differences are critical when planning a landscape, and they’re the kinds of details experienced nursery professionals consider every day.
A Real-World Example
Recently, a customer visited Blackcreek Nursery with a landscape plan generated by ChatGPT. The overall design was attractive, but one planting bed immediately stood out.
The space was only three feet wide, yet the plan called for a Loropetalum, Gardenias, and Roses to all be planted within that narrow bed.
Each of those plants can be an excellent landscape choice. The problem wasn’t the plants—it was the spacing.
A typical Loropetalum can eventually spread six to ten feet wide, depending on the variety. Gardenias need room for healthy growth and good air circulation, while roses perform best when they have adequate sunlight, airflow, and space for maintenance.
Within just a few years, those three plants would be competing for the same space. Instead of a beautiful planting, the homeowner would likely face overcrowding, constant pruning, fewer blooms, and stressed plants.
Rather than simply selling the plants on the list, we explained why the design wouldn’t perform well and recommended alternatives that maintained the same look while giving each plant the room it needed to thrive.
That’s the difference between creating a picture and creating a successful landscape.
It’s More Than Just Size
Experienced gardeners also consider many other factors that AI may overlook:
- Mature height and width
- Root systems and their impact on sidewalks, foundations, septic systems, and utilities
- Sun versus shade requirements
- Soil type and drainage
- Water requirements
- Heat and humidity tolerance
- Disease resistance
- Air circulation
- Seasonal interest
- Long-term maintenance
- Wildlife value
- Invasive tendencies
- Local availability
These details often determine whether a landscape flourishes or struggles.
AI Is a Wonderful Tool
None of this means AI isn’t useful.
In fact, it can be an outstanding source of inspiration. It helps homeowners visualize ideas, compare design styles, experiment with color palettes, and think creatively about outdoor spaces.
We encourage people to use AI.
Just don’t stop there.
How to Get Better Landscape Designs from AI
AI is only as good as the information you give it. The more details you provide, the more realistic and useful your design will be.
Here are a few ways to improve your results:
Tell AI Where You Live
Don’t simply ask for a beautiful landscape. Tell it your city, state, USDA Hardiness Zone, or at least your general region. A garden that thrives in Oregon won’t necessarily thrive in southeast Georgia.
Describe Your Site
Include details such as:
- Bed dimensions
- Full sun, partial shade, or full shade
- Sandy, clay, or well-drained soil
- Wet or dry areas
- Existing trees, structures, or utilities
- Your desired style
The more specific you are, the better your results will be.
Ask for Mature Plant Sizes
Instead of asking for “pretty shrubs,” ask:
“Recommend shrubs that mature no wider than four feet.”
or
“Only suggest trees that will remain under twenty feet tall.”
Request Regionally Adapted Plants
Try asking:
“Recommend plants that are commonly available at independent garden centers in southeast Georgia.”
AI can’t know every nursery’s inventory, but this prompt encourages it to recommend plants that are more realistic for your area.
Ask About Spacing
Before accepting a design, ask:
“Show the mature spacing required for each plant.”
or
“Will these plants be overcrowded in five years?”
Those follow-up questions often reveal problems before you ever begin planting.
Think Long-Term
Ask AI to design for mature landscapes, not newly installed ones.
A great prompt is:
“Design this landscape using the mature size of each plant, not the size of nursery stock.”
Ask for Alternatives
A smart follow-up prompt is:
“Suggest three alternative plants for each recommendation in case my local nursery doesn’t have the original selection.”
That gives you flexibility when you go shopping.
A Prompt You Can Copy
If you’re using AI to help design your landscape, try starting with a prompt like this:
Design a landscape for my home in southeast Georgia (USDA Zone 9a). The planting bed is 20 feet long by 6 feet wide and receives full morning sun with afternoon shade. Recommend plants that are commonly available at local independent garden centers. Include the mature height and width of each plant, proper spacing, and choose varieties that are well adapted to our hot, humid climate. Avoid invasive plants and high-maintenance selections. Explain why each plant was chosen and suggest alternatives if a particular plant isn’t available locally.
The more information you provide, the better your results will be.
The Best Garden Designs Start with a Conversation
Perhaps the best companion to AI isn’t another app—it’s your local garden center.
A knowledgeable nursery bridges the gap between inspiration and reality. They know which plants actually thrive in your area, what’s available this season, and which varieties are best suited to your soil, climate, and growing conditions. They can help you avoid costly mistakes like planting a tree too close to your home, choosing shrubs that quickly outgrow their space, or combining plants with conflicting water and sunlight needs.
At Blackcreek Nursery, we enjoy seeing the creative ideas our customers bring us—including AI-generated designs. Our goal isn’t to replace those ideas but to refine them using years of hands-on horticultural experience.
We can recommend plants that are available locally, suggest better-performing alternatives, adjust spacing for mature growth, and help create landscapes that will still be beautiful ten or twenty years from now.
Think of AI as a sketch artist. It can help you visualize possibilities and inspire creativity. But before you start digging holes, take that sketch to your local nursery. That’s where years of horticultural experience turn a beautiful idea into a beautiful landscape.
AI can help you imagine what’s possible.
Your local nursery helps make those possibilities grow.
The most successful gardens don’t come from choosing between AI and human expertise—they come from using the strengths of both.
