2025 was a year of big changes for both people and companies in the greenhouse industry, from new CEOs — including the first non-family CEO in one legacy business’ 120-year history — to big mergers.

This year also saw lots of updates on labor in the horticulture industry. With a new presidential administration beginning in January and focused on U.S. labor and immigration crackdowns, significant effects were felt in the realm of H-2 visa programs. Several lawsuits related to the programs were also filed this year.

Here are the top stories we covered in 2025 to help you prepare for the new year:

This holiday season, Editor Patrick Alan Coleman is reflecting on the warmth and light in the horticulture industry:

"Without the long, bright days, it’s time for us to make our own light. So, we burn candles at holiday tables and festoon our houses with bright, colorful bulbs. We are comforted by the twinkling of Christmas trees, the flicker of flame on the menorah, the crackling of the yule log on the fire. But there is another light that should warm us as well: the light we find in each other."

It’s funny how a favorite song, a familiar movie or a small holiday tradition sticks with us year after year.

The holidays have a way of doing that. They remind us of where we’ve been, what we love and the moments that still make us smile.

This season, our team put together a short video full of our favorite things that make this time of year feel special, and we hope it makes you smile.

Thank you for being part of our year. We’re grateful for the collaboration, the conversations and the partnerships — and we’re looking forward to more in the year ahead.

Wishing you a holiday season filled with joy and all your favorite things ✨

📖 Our December issue is out now! On the cover:

In 1986, Patty Robertson was a buyer for one of Miami-Dade County’s premier garden centers. It was one stop on a lifelong horticultural journey.

As a little girl, she’d fallen in love with gardening by watching her mother grow roses. That love parlayed into a degree in landscape technology and design.

There was no questioning the knowledge and thought she placed into her purchasing decisions for the Florida garden center. Every day, vendors would pull up with trucks full of plants, and she would peruse their options and pick what she needed.

Little did she know that one of the most crucial picks she’d ever make would also arrive at her garden center in a truck.

But it wouldn’t be a plant.

It would be Mitch Rabin.

Find out how the Rabins' love and legacy brings vibrant bromeliads to homes and gardens year-round at Living Colors Nursery, Inc. 🌈

Breaking news: Metrolina Greenhouses and South Central Growers, Inc. today announced a strategic merger, effective Jan. 1, 2026, with the combined organization operating under the Metrolina Greenhouses brand.

The South Central Growers brand and social media platforms will be retired effective Jan. 1.

“At its core, this merger is about growth,” said Abe VanWingerden, CEO of Metrolina Greenhouses. “Growth allows us to invest more, serve customers better and create more opportunities for our people. This partnership enables us to grow faster and smarter by bringing together two highly aligned teams.”

Despite strong consumer demand for live goods, the horticulture industry continues to experience consolidation driven by rising capital requirements, operational complexity and heightened customer expectations. Leaders from both companies said the merger represents a proactive response to these complex dynamics.

“The industry is changing rapidly, and consolidation isn’t slowing down,” said Alex Van Der Hengst, CEO of South Central Growers. “We’re passionate about this business and wanted a path that allows us to continue operating, growing and investing at a higher level. This merger gives us that opportunity while keeping our leadership team deeply involved.”

A quick visit to the produce section of your local supermarket or grocery store reveals that virtually all culinary herbs have already been cut and packaged with a ticking expiration date or are dried. However, you would be hard-pressed to find a grocery store that doesn’t have potted basil, as it is probably the most popular grow-it-yourself herb on the market.

Unfortunately, basil growth is often difficult to control and can often become tall, scraggly or even bent over once it has been in the grocery store a few days. As it stands today, there are no chemical plant growth regulators labeled for edible culinary herbs.

This poses two problems for growers: how to grow aesthetically pleasing potted herbs that are proportional to their containers, and how to ensure the plants fit on shipping racks without causing damage or increasing the cost to ship them. Finding a way to optimize plants for distribution and aesthetics kills two birds with one stone.

Seth Benjamin and Roberto Lopez from MSU Department of Horticulture propose the use of ultraviolet radiation as a potential growth regulator.

Learn how to use UV-A lighting to regulate potted basil growth and reduce stem elongation without chemical growth regulators 🌿

Although Suntory Flowers' activities are global, gardening is a regional industry.

The most successful programs start with a regional mindset — how will these plants perform in my climate? And the most efficient way to supply plants to retailers is regionally.

When Suntory rolls out its introductions, the company trials them in more than 20 locations across the U.S. and Canada.

Suntory said Petunia ‘Surfinia Heavenly Cashmere Pink’, Dipladenia ‘Sun Parasol FiredUp Orange’, Granvia bracteanthas, Soiree catharanthus and Tapien & Temari verbenas received rave reviews.
