About ONLA

The Mission of the Association shall be to advance the Nursery, Greenhouse and Landscape
Industry through Networking, Education, Scholarship, Industry Promotion and Certification
with a strong, healthy and sustainable organization.

Ninety-three years ago a group of nurserymen in Oklahoma formed our association.  Since then the nursery industry has changed dynamically to encompass wholesale nurseries and greenhouse operations, retail nurseries and greenhouse operations, landscape services from designing to building to maintaining, vegetable production, wineries, florists, cut flower, interior-scape, hardscape and turf industry and all companies that supply and service the green industry.  The association has worked at broadening and enhancing its services, education, and fellowship to include all facets of the green industry in our great state.
The Oklahoma Nursery and Landscape Association is dedicated to bettering your business by means of education, political outreach, networking, environmental stewardship and fellowship. We hope that no matter what aspect of the green industry you are in, you will find the acceptance and excellent resources needed to help you and fulfill your business needs.

Landscaper of the Year Award Winners

During the ONLA Convention and Trade Show, we hold the Landscaper Games.  Several landscaping teams compete for the title as they design and build their landscape with limited time and materials.  Only one team walks away as the champion, taking home the title, a trophy and cash. 

Will your team be the next Landscaper of the Year?  Join us at the 2017 show and find out!

2016 Recipients:  TLC Garden Centers

TLC Garden Centers held on to their title for a second year.  The format stayed the same from 2015, but the "twist" was a little different.  One team member was taken "off the job" to visit all of the trade show exhibitors looking for answers to 15 questions ranging from plant ID to chemical makeup of various pesticides to parts of a tree.

50% of the score was based on judge's scoring, 25% was based on the question and answer "twist" and the final 25% by attendee voting.  Congratulations, TLC!

2015 Recipients:  TLC Garden Centers

The teams had two hours to plan and execute their plan, while dealing with two "twists": a 30-minute Plant ID test and an irrigation system addition during the last ten minutes.

Judges and convention attendees had a hand in choosing the winner, the team from TLC Garden Centers in Oklahoma City.

One member of the team was last year's winner, Wendy (Johnston) Simmons.

2014 Recipient:  Wendy Johnston

In our first year of the competition, Wabi Sabi West of Edmond was represented by three competitors.  They began the games with Plant ID followed by paver design, wall building, irrigation installation and finally patio design.

Wendy Johnston bettered her workmates to win the title!
