Revolutionary home decor store TreeHouse Dallas opened on June 1 with an unrivaled welcome party that felt more like a shindig at some swanky mansion than it did a retail launch.

The Austin-based company is a first-of-its-kind home improvement store. Its products and services promote healthy and sustainable spaces and thoughtful building. Dallas is the second location; a third is penciled in for Plano.

TreeHouse Dallas is the anchor tenant in the new The Hill redevelopment, the shopping center at the northeast corner of US-75 and Walnut Hill Lane that's being refashioned into an open-air retail center with a new slate of dining, home, and healthy-living concepts.

The crowd at the event was eclectic and artsy, from sunglasses-at-night splendor to longhairs in tie-dye T-shirts. Staffers from nearby restaurants Nazca Kitchen and Red Hot & Blue BBQ — such a cool neighborly move — rolled out tray after tray of snacks from the store's high-tech in-house kitchen. Bartenders from the Grand Bevy concocted New-Age themed cocktails with names like Water and Metal, served in real glassware, not disposable plastic. Thank you!

The Dallas location is the first energy-positive big-box store in the world, meaning the store will generate excess renewable energy using solar panels, battery packs, and cutting-edge architectural design, then send unused energy back into the city grid.

TreeHouse provides progressive products, great design, human-centered services, and leading-edge technology. A sample of unique products in which TreeHouse is the only retailer include:

Haiku ceiling fans. The Haiku ceiling fan is described as the most advanced ceiling fan in the world, reducing energy use through elegant design, incredible performance, and exceptional efficiency, as they are 700 percent more efficient than a standard ceiling fan.

Haiku lights. From sleek design and long-lasting LEDs to its range of user-focused features, Haiku Light fixtures represent effectiveness, convenience, and efficiency at the highest level. With more than 2 billion unique feature combinations, Haiku Lights produce 50 percent more light than a typical 60-watt incandescent bulb and last more than 30 times as long.

Romabio paint. The world’s first cradle-to-cradle certified paint, Romabio is among the healthiest, most beautiful, and durable paints available in the world today. Romabio paints are derived from natural sources, using minerals and sustainable resources.

Other state-of-the-art TreeHouse products include:

A Tesla Powerwall, the groundbreaking battery for the home.
Nest smart home products including the Nest Cam, Nest Protect, and Nest Thermostat.
Nebia Shower Head. This Tim Cook-backed Kickstarter phenomenon conserves thousands of gallons of water per year by atomizing droplets to create 10 times more surface area and offers a spa-like shower experience.
Dunn-Edwards Paint. Dunn-Edwards' mission is to provide the best-performing latex paint in an environmentally responsible manner. Its Zero Volatile Organic Compound (VOC) colorants perform the same as conventional colorants, but with no added VOC solvents. Zero VOC paint can remain 100 percent Zero VOC, even when tinted to the deepest colors.
Bolefloor. The world’s first industrial-scale manufactured hardwood flooring features naturally curved lengths that follow a tree’s natural growth.

Founder Jason Ballard made a speech about our responsibility to the planet that was so stirring, some attendees said they were moved to tears.

“We asked ourselves what a home improvement store would look like if it were an answer to the question, ‘What is needed to actually help people make their homes better in every way?’ and everything else flowed from there," Ballard said. "We hire the best people. We educate, inspire, and collaborate. This is home improvement as it should have been all along.”

TreeHouse is now in the midst of a giveaway program that runs until June 11, in which customers can enter to win prizes such as a Nest Thermostat, a Festool drill kit, Dunn-Edwards paints, a GreenPan 11-piece Venice pro set, a 150-gallon Poly-Mart rain barrel, Berkey water filters, and a Lollygagger outdoor lounge chair.

Floral studio in booming Celina blossoms with plans for full flower shop

Tucked behind the sprawling grounds of Shades of Green, a 10-acre garden center in Celina, sits a house where Rebecca Calvert and Julie Holland often work into the wee hours creating floral arrangements for their Greenologie Flower Shop.

Open since June 2025, Greenologie is a boutique floral design studio that offers handcrafted floral arrangements, flower delivery or pick-up, floral design workshops, and wedding and event floral design services. For the last year, Calvert and Holland have been operating from Shades of Green, by appointment only.

But the floral business is booming in Celina - one of the fastest-growing cities in the country - and the duo has ambitious plans to transform the floral business into a traditional flower shop. They're used to putting in the long hours it will take to make it grow.

“We flower-design a lot at nighttime,” Calvert says. “We always joke — because the lighting isn't great — that we're kind of designing in the dark. The next day we get over there, and we're like, oh, it's really, really beautiful.”

In addition to making custom floral arrangements, Greenologie also offers flower arranging classes for the public, including the upcoming Sips & Stems: Wine Glass Flower Arranging Night, on July 15 at Valley Vines in Celina.

Last fall, the company launched a porch decorating service called Pumpkin Porch Party, which featured multi-colored pumpkins, gourds and seasonal flowers. It was a hit, and they plan to offer the service again this year.

“People pay you to zhuzh up their porch,” Calvert says. “We launched it last minute, and it went really well. We did about 30 porches over North Texas and it was super fun.”

Calvert co-owns Greenologie and Shades of Green Nursery + Landscape with her husband, Jarratt Calvert. Flowers are a family business.

Rebecca Calvert’s father, Jeff McCauley, opened Shades of Green in 1977 with a childhood friend while they were students at Texas A&M University. The first Shades of Green garden center opened in McKinney in 1988 before relocating to Frisco in 1994. In 2022, a second location opened in Celina, which is now the company’s sole Shades of Green garden center.

Calvert and Holland have to be nocturnal florists because of their day jobs at Shades of Green.

After graduating from Texas A&M University with a degree in communications, Calvert, a longtime Celina resident, spent nearly a decade working in corporate human resources. Following the birth of her first child, she decided to leave the corporate world and found a new way to use her HR experience through her work at Shades of Green.

“I would say [Shades of Green] is the job I have to do, and Greenologie is the job I get to do,” Calvert says.

Holland, the garden center manager and a Celina resident, earned a degree in agricultural services and development with a focus on horticulture at Tarleton State University. Prior to beginning her career at Shades of Green four years ago, she taught floral and horticulture classes and ran a flower shop from her classroom. Holland traces her botany bond back to her grandmother, whose flower shop she loved visiting as a young girl.

Calvert says she and Holland share responsibilities as well as a similar design aesthetic.

“We are more on the contemporary side — whimsical is a good word,” Calvert says. “We've done a few events and weddings where it was kind of copy and paste, and that's great too. But we both have the most fun whenever we can design without any constraints.”

The owners' goal is to open their own brick-and-mortar shop in the next five years. For now, orders placed online for Greenologie can be delivered or picked up at Shades of Green, 1213 E. Sunset Blvd., Celina.

“Greenologie will have its actual own little flower shop next to the Shades of Green storefront,” Calvert says. “It will be a traditional flower shop with gifts and a flower bar to pick your flowers from.”
