A Midwest Proving Ground: Inside Green Legacy’s New Trial Garden

November 19, 2025

When Green Legacy broke ground on a one-acre trial garden in rural Ohio, they set out to do something different. Few trial gardens are located in the Midwest, and even fewer are built for landscapers. So, they created one, rooted in realistic growing conditions and designed for the people who shape the region’s landscapes.
Launched with a $100,000 budget in partnership with EMI — and with the support of 25 sponsors, EMI staff, and Green Legacy staff — the trial garden in Orient, Ohio, opened its gates to the public on August 15, 2025.

Today, more than 40,000 plants representing over 450 varieties fill the site, arranged not as sterile rows but as a living landscape. Irrigation rains down from overhead, shade structures break the sun, and seating areas invite visitors to linger.

Those were intentional design choices meant to mirror the conditions landscapers work with every day. “It’s not just about making it nice for visitors,” Brill said. “We wanted the setup to look and feel like what landscapers actually deal with on site.

Green Legacy wanted to create a space that not only tests plants but models what the future of Midwest commercial landscaping could look like. The idea took root months earlier in a conversation between Dan VanWingerden, Owner of Green Legacy, and one of their key customers, EMI.

They were telling us what they wanted to buy,” said Audrey Brill, Trial Garden Coordinator. “Dan wanted to flip that so we could show them what they need.

Brill, a recent graduate of Ohio State with a degree in Sustainable Plant Systems, was originally a math major, but switched paths after a general education course in horticulture. “I thought, why be an accountant when I can hang out with plants all day?” Now, as Trial Garden Coordinator, she leads the day-to-day work of the garden with a small team of seasonal help.

A Rapid Rollout with Industry Buy-In

After initial brainstorming in October 2024, the project moved from design to execution in a matter of months. By the end of February 2025, VanWingerden had called 20 breeders. Nineteen signed on. Construction began in March. And by Memorial Day weekend, planting was underway.

Each breeder selected and shipped their own showcase varieties. Many even designed their individual beds. The only ask? Make it beautiful.

Dan’s goal for this first year was beautification,” Brill said. “The breeders gave us things they thought we should showcase in the Midwest landscape.

Midwest-First, Landscaper-Focused

Unlike container-heavy trials in other parts of the country, Green Legacy planted directly into the ground using pop-up overhead irrigation to mimic real-world landscaping conditions.

We were prioritizing mirroring what landscapers actually do,” Brill said.

This landscaper-first approach is rare in trial gardens, especially in the Midwest, where few trials exist outside of Michigan.
EMI’s involvement also sets this trial apart: the team regularly checks in with them to understand what metrics would actually be useful to the field.

We have EMI to ask, ‘What metrics would be helpful for you to know from the trial garden? What kind of things do you want to see that would be beneficial for people in your industry?’” Brill said.

That collaboration underscored the garden’s purpose: not just to look good, but to deliver insights landscapers can use.

Also being so close to Cultivate, one of the biggest events in the industry each year, is really helpful too,” Brill said.

Measuring and Seeing Performance

Brill’s work this first season centered on establishing the garden — only midseason did she begin capturing the plants’ performance.

This first year, it was kind of a trial for us, too. We were learning so much, and we wanted it to look as gorgeous as possible. And data collection… we weren’t even considering it in the beginning,” Brill said.

Still, she started tracking performance on August 1st using a basic five-point scale. Each variety was scored for overall performance, resistance, uniformity, vegetative growth, and flowering. To do it, Brill printed spreadsheets, carried them into the field, and filled them out by hand.

When I was going out there and rating each plant, I would print a spreadsheet out and just write it,” she said. “Especially because the [internet] service isn’t great. Paper and pencil is easiest.

Plants that scored 4.6 or higher earned a spot in Green Legacy’s 2026 catalog.

One of the top performers was Ageratum ‘Monarch Magic’ — which Brill described as a “butterfly magnet.

I’ve seen over 50 butterflies on just the one plant,” she said. “It’s insane, and everybody who came to visit the trial garden mentioned it.

Proven Winners’ Cleome and Helianthus also stood out, holding their color and performance longer than other comparable varieties, Brill noted.

PanAmerican Seed’s zinnias surprised her, too. “Zinnias are one of those flowers you see everywhere because they’re so easy to grow,” she said. “So, I didn’t think too much of it, but everybody was very impressed with them.

Brill’s personal favorite was the dwarf Buddleia called ‘Little Rockstars’ from Dümmen Orange. “It’s like a mini butterfly bush,” she said. “Usually, when I see mini butterfly bushes, they’re a little scraggly, but these were really compact and full. I was really pleased with those, too.

What’s Next (And What They Hope to Achieve)

Green Legacy Trial Garden

Feedback has already shaped next season’s approach. For starters, Brill plans to rate plants biweekly and expand metrics to include bloom time and pollinator activity. She’s also shopping for a data platform that would let Green Legacy share results live on their website.

I’ve been asking about software and what other trial gardens use,” she said.

In pursuit of the perfect tool, she will attend the International Plant Trialing Conference in Minnesota next month, where there will be an entire session dedicated to digital data tracking.

I’m going to that conference to hopefully learn about some kind of software, so that when I take data, I can immediately put it into the [system] and it’ll upload to our website so that it’s more of a public, ‘anybody can use this information’ kind of thing.

The trial garden was always meant to be a resource, not just a display.

The goal is to make this useful to as many people as possible,” she said.

Visitors — from landscape pros to curious passersby — are already taking notice. Some take notes. Others leave with ideas. And more than a few have walked away asking how they can start buying from Green Legacy.

Plans are already in place to expand the trial garden to four acres, which triples its current size, with perennial beds added for multi-year trials.

But Brill emphasized that even with the eventual expansion, their mission remains the same: highlight new plant varieties and landscape performance, beautify the Midwest, and give decision-makers data they can trust.

We want people to have access to the highest-performing plants,” she said. “And we hope to be one of their resources for figuring out what those are.

When Hurricane Helene Devastated Carolina Native Nursery, the Community Rallied Together to Rebuild

September 18, 2025

Hurricane Helene damage

It was a sunny Friday afternoon, September of 2024, when the storm had finally cleared in North Carolina.

Bill Jones drove from his home in Asheville to Carolina Native Nursery, his business in Burnsville, just 30 minutes away.

Although he expected storm damage, he did not expect to find thousands of black pots scattered across the valley or three feet of water still rushing through his shop.

We’ve had hurricanes come through here before,” Jones said. “But nothing like this.

Hurricane Helene dropped 30 inches of rain over western North Carolina in just three days. The trout stream that bordered the nursery swelled from 10 feet wide to 100 yards across and five feet deep.

Water tore through the operation — washing away 90% of Carolina Native’s plant inventory, destroying greenhouses, and leaving behind a tangled mess of debris.

Despite running through their hurricane checklist, which includes securing the property and ensuring there aren’t logs in the trout stream or feeder creek, nothing could have prepared the property for what was to come.

The plants were gone, a lot of the gravel was gone, many of our greenhouses were either damaged or destroyed, and so it left us with just piles of stuff,” Jones said. “You can’t stop water like that. There’s just no physical way to do it.

Jones tried to reach the nursery on three different roads that Friday. What he found was total devastation.
We had to climb through downed trees,” he said.

Not only was their shrub yard and perennial farm destroyed, but the road above the nursery suffered a landslide, damaging the top of the property, and the bottom of the property had been washed away.

All the phone lines were down, all the power was out. I tried to go find a woman who works here and is part-owner of the nursery — I couldn’t find her, I couldn’t get to her house,” he said.

Hurricane Helene damage

Feeling helpless, that’s when Jones and his wife got back in their car and went home because at that point “there was absolutely nothing we could do,” he said.

Where to Go From Here?

Before the rebuild, filing an insurance claim was imperative. “Luckily, we have crop insurance,” Jones said. “Without the crop insurance we had, we never would have been able to afford to bring in all the stock to replant.

By Thursday of the first week, volunteers began arriving. Landscape firms closed for the day and brought equipment.

We had over 100 people out here helping us get all the trash out,” Jones said. “It was sort of helter-skelter at first, but we started our rebuild and we’ve been working on that ever since.

Lost Inventory and The Community’s Response

Some plants survived — a few thousand up the hill were out of the flood’s reach. But others had gotten an inch or two of water in the base of the pot.

Even though those plants were salvageable, the Department of Agriculture deems them unsellable once they’ve sat in flood water.

For those plants, Jones and his team set up a donation program.

We ended up donating well over 6,000 plants to nonprofits and volunteer groups trying to replant people’s stream banks and gardens,” Jones said. “That ended up being a beautiful thing.

Jones doesn’t know how they could have gotten to where they are now without over 100 volunteers helping to pick up the property.

Hurricane Helene damageThe community support, he said, was humbling.

As an entrepreneur, you’re used to doing it yourself,” Jones said. “My wife was like, ‘You’ve got to accept these people’s help and let the volunteers come because all these people want to do it.’

Jones partially attributes the outpouring of volunteers to the one-of-a-kind products Carolina Native offers.

We are the native nursery that services this whole geographic area — the landscapers, the garden centers — and we’re sort of irreplaceable in the plant palette that we grow,” he said. “People needed us back up and running because they need what we have to do their work.

The nursery launched a GoFundMe campaign that raised $150,000 and even received checks in the mail from strangers.

In the long run, I think it’s made me a much more grateful and humble person,” he said of the support they received from all over the country.

A Three-Year Recovery

Jones estimates the nursery suffered about $2 million in damages. Crop insurance — a federally supported program he urges all growers to look into — covered roughly half of that value.

The nursery lost fourth-quarter sales last year and much of the spring season this year. But sales have now rebounded. Staffing has returned. Facilities are nearly rebuilt.

With our perennials and our shrubs, we’ve recovered tremendously in sales,” Jones said. “With the azaleas, it’s going to be a while. But sales-wise, we’re in really good shape.

Among the hardest losses to absorb were Carolina Native’s native azaleas — a specialty crop that Jones’ team grows from seed.

We harvest the seed late in the fall, right after Thanksgiving,” Jones explained. “Then we grow the seedlings into liner trays the first year, into 1-gallons the second year, and 3-gallons the third.

The nursery had tens of thousands of native azaleas on the ground across all stages — and lost nearly all of them.

All the 1-gallons and 3-gallons were gone. A lot of our liner stock was gone,” Jones said.

With 13 species of native azaleas indigenous to the eastern U.S., Carolina Native is the largest grower of these plants in the country (they sell all 13). And because they can’t outsource this part of the business, rebuilding stock will take time.

It’s going to be a two- to three-year process,” Jones said.

Meanwhile, the nursery’s perennials, ferns, grasses, and other native shrubs — sourced from outside growers — have bounced back quickly.

Hurricane Helene damageWe already had those orders in the hopper,” he said. “So all that stuff we’re up and running on.

Same Mission, New Perspective

Despite the upheaval, the nursery’s mission hasn’t changed.

We grow beautiful, high-quality native plants for IGCs and landscapers,” Jones said.

He has no plans to change locations, either.

In western North Carolina, the only flat land is near streams and rivers, and that’s where we are. We’re not moving,” he said. “We love western North Carolina. I sold my organic lawn and shrub care company in Charlotte to move up here to do this and raise our kids in the mountains.

That commitment to place — and to the people they serve — has paid off.

Whether [our clients] are wholesale or retail, garden centers or landscapers, they’ve come roaring back,” he said. “They were just waiting for us. They didn’t turn and start buying from other nurseries.

Advice to Other Growers

Having gone through Hurricane Helene, what advice does Bill have for other growers, particularly those in vulnerable regions?

If you haven’t examined crop insurance and put that as an expense line, it will save your business,” Jones said. “It’s a federal program that is available to everyone who grows a crop.

And secondly, if you are met with disaster and people want to volunteer to help, let them. You can do it all yourself. But why? It makes you feel good. It makes them feel good.

Today, Carolina Native is almost totally renovated. There are just a couple of greenhouses at the corner of the nursery to rebuild that Jones likens to “having one room left to paint before being done with the house.

But ultimately, he’s incredibly proud to have gotten back to mostly normal operations after such a devastating blow from Hurricane Helene.

We’re just so happy to be selling plants again,” Jones said. “And that’s what everybody’s working on, either growing or selling. We’re just so grateful to everybody that’s helped us.

 

At Willoway Nurseries, Smarter Spraying Means Better Labor Use and Healthier Plants

July 7, 2025

Willoway Nurseries, Avon Ohio

Thad Kohlenberg (left), Will Mihalega (right), and Willoway’s first-generation smart sprayer

At Willoway Nurseries in Avon, Ohio, better spray technology is translating directly into healthier, more resilient plants.

This smarter, more precise approach to spray application is not only improving plant performance but also folding staff back into the nursery to perform more strategic work.

On a recent visit, their team walked us through three newer technologies in their spray lineup: a Birchmeier backpack, a Gandy granular applicator, and the centerpiece: a “smart sprayer” developed with the USDA.

Replacing the Guesswork in Spray Application

Willoway Nurseries, Avon Ohio

Willoway was one of the first growers to test the USDA’s smart sprayer system. The first version uses laser sensors to detect when a tree is present.

Each spray nozzle is controlled by an electric solenoid that adjusts in real time based on tractor speed and canopy size.

You can have taller trees on the left and shorter ones on the right, and it adjusts on the fly, explained Head Grower Manager Thad Kohlenberg.

Despite the sprayer’s advanced capabilities, it’s been easy to use.

“It’s just a basic iPad up there. There’s nothing really technical to operate,” said Will Mihalega, who oversees plant health. “It’s all pretty simplified.”

And that’s just the first generation.

Version two – a system that scans canopy shape using imaging instead of lasers – made application even more optimized.

“A camera takes thousands of images, and you can make a digital representation of the
actual pattern of the branching, and it adjusts the sprays to that,” said Kohlenberg.

“It takes the silhouette of the tree and only sprays the silhouette,” described Ben Averitt, Staff Horticulturalist – R&D at Willoway.

The third generation is more versatile. It’s smaller, lighter, and modular, designed without a power take-off (PTO) so it can mount on lighter vehicles and navigate tighter rows.

A Toolkit of Sprayers

The smart sprayer isn’t doing it all alone. Willoway also uses an Orbit-Air Gandy granular applicator, a converted seeder with a 24-foot boom and air assist blower, to apply pre-emergent herbicide across field rows.

Willoway Nurseries, Avon Ohio

Before they started using the Gandy three years ago, five workers went up and down the rows wearing a respirator mask, each covering 11 miles a day.

Now the Gandy, operated by one person, can do the job in the same amount of time.

“It puts the most perfect pattern across that area,” said Mihalega.

The granules on the herbicides were so fine that they were nearly invisible coming out of the nozzles.

“You can see [it’s] even all the way across if you look at the pot,” Kohlenberg said.

Not only does the Gandy applicator deliver an ultra-consistent pattern, it’s also dramatically improved weed suppression.

“The weed control is so much better. We used to have sporadic weeds in there,” Mihalega pointed out. “Now it’s just crystal clean.”

Their third go-to tool is the Birchmeier backpack sprayer, a compact, air-assisted tool ideal for tight greenhouses and property edges.

“It’s basically a little air blast in your hand,” Mihalega said.

The team uses it to target areas a big tractor can’t reach – like under bamboo stakes or along neighboring property lines – without risking chemical drift.

“It’s got a handle [where] you can turn the fan up and down to suit different distances,” Kohlenberg added. “And also, you can change the droplet size on it.”Willoway Nurseries, Avon Ohio

Tech That Pays Off Every Day

For a nursery operating at Willoway’s scale, the benefits are straightforward: smarter spraying frees up skilled labor, offers better consistency, and produces healthier plants.

“It’s one of the things that people are most interested in when they visit,” said Kohlenberg. “It’s not highly adapted in the industry, but it’s probably something everybody should be looking at for the investment.”

These tools are helping nurseries become more efficient in the constant push to do more with less.

In the past five years, Willoway’s labor expenses have jumped 45%. Smarter spraying gives them the flexibility to continue operating efficiently… even grow.

As the nursery scales up use of biological controls, sensor-driven fertigation, and degree-day pest prediction, they are seeing healthier crops, fewer inputs, and more consistent production.

“It comes back to sustainability – reducing our cost of imports for producing a plant,” said Kohlenberg. “And then we’re getting better results with the application and [reducing] wear and tear on guys.”

 

Willoway’s Secret to Moving 36,000 Hydrangeas? Six Driverless Burros

June 20, 2025

You might find yourself doing a double take at Willoway Nurseries in Avon, Ohio, where self-driving vehicles are the new norm.

Spread across 1,000 acres, the operation recently deployed six autonomous tractors from a Philly-based company called Burro, and their impact on efficiency has been immediate.The Burros arrived in spring and are already proving to be reliable haulers in the nursery’s canning process, delivering newly potted plant material to designated drop-off points. Willoway automated burro in Avon Ohio“We got a fleet of six of them back in March,” said Willoway’s Staff Horticulturist – R&D, Ben Averitt. “We’ve mostly been using them for our canning process, for delivering newly canned material to the set downs.” Each unit runs on preprogrammed routes built from drone-generated maps and custom overlays. It’s a setup that takes time to establish, but once in place, the system becomes intuitive. “It’s a slow process, but then once you have it all drawn, you punch in the location you want it to go to and it finds the best route to get there based on the information it has,” Averitt explained.

Willoway Burro in the nurseryFor light loads, speed is intentionally limited to about 2.5 miles per hour to prevent plants from jostling off tractor beds during transport. Still, even at that speed, the Burros are making a difference. “It’s saving us a body moving back and forth on a tractor,” Averitt noted. The labor efficiency afforded by the Burros has been massive. Add in a forklift for unloading and “now we’ve taken a four-guy process down to one guy,” said Averitt. The other three workers, now freed up from repetitive driving, are deployed to higher-value nursery work like trimming, spacing, and fertilizing. Besides their efficiency, the Burros are clever and surprisingly interactive. Outfitted with sensors, they can detect obstacles within six feet, stop at intersections, and emit a short honk as a safety measure. Willoway Burro ready to workThey can also follow a worker around the nursery, a feature Averitt likened to “a little puppy dog.” Currently, each unit must be manually started every morning, but updates are on the horizon. An autonomous docking station is in development, which will allow the Burros to charge themselves overnight and begin work on a preset schedule. “We’ll be able to home, dock, plug in, and then [it can] unplug itself. Say, six o’clock in the morning, you want it up and running, and bam, there it is,” Averitt said.

In terms of strength, the Burro Grande is rated to tow up to 5,000 pounds, though the Willoway team has tested it with loads up to 9,000 pounds with no complaints. Recently during a large contract order, the Burros moved 36,000 hydrangeas with remarkable speed and consistency. “We set up a superhighway for them,” Averitt said. “It was a slick setup.” The company is already planning further tech integrations. RFID tagging is being explored for real-time inventory mapping, and one of the Burros will soon be fitted with a mower. There’s also potential to attach sensors for thermal mapping and monitoring heaters in the winter. Willoway is one of the first nurseries in the country to use this technology, receiving the hundredth Burro ever produced.

Willoway Burro, the new automated workhorse of Willoway Nurseries in OhioTheir property is also the largest operation the machines have been deployed on to date. Willoway’s early adoption and expansive footprint has made it a pioneer in the industry, a case study for integrating automation. Learning to use the Burros has been relatively easy. Averitt estimated that most staff are up and running with the system in about two hours. One of the company’s H-2A workers has become the in-house expert, regularly updating maps on his phone and helping others navigate the system. As with any new tool, there’s been a cultural adjustment. Averitt laughed when recalling some of the early reactions. “One of our biggest issues was that people wanted to pet them,” he said. Willoway Burro carrying nursery containers in Avon, Ohio“There’s a lot of jokes about who’s the real burro—the machine or the guys. ” Jokes aside, the benefit is clear. “When these things are working, which is 90% of the time, they’re awesome,” Averitt said. “We can cook with peanut oil with these things.”

Automation isn’t replacing workers at Willoway, it’s allowing them to do more specialized tasks. And on a 1,000-acre nursery with no time to waste, that kind of ROI speaks for itself. “The whole goal is to take out the mindless work,” Averitt said. “What these guys are really good at is their job. Why have to drive a tractor?”
