Could certain ornamentals help support pollinator biodiversity?

HRI-funded research led by Dr. Gail Langellotto at Oregon State University is studying “magnet plants”—ornamentals that may draw honeybees away from native plants and reduce competition with wild pollinators.

The goal: help design landscapes that support pollinator diversity.

Water conservation and pollinator support are shaping plant choices in modern landscapes.

HRI-funded research led by Dr. Ryan Contreras at Oregon State University is studying whether polyploid ornamental cultivars can perform well under reduced irrigation while still supporting pollinators.

The goal: help growers and landscapers select resilient, pollinator-friendly plants.

Crapemyrtle bark scale is a growing challenge for landscapes and nursery production.

HRI-funded research led by Dr. Hongmin Qin at Texas A&M University is developing RNA interference (RNAi) spray technologies that target essential genes in the pest.

The goal: provide more precise pest control while minimizing impacts on beneficial insects.

We’re launching a new series introducing you to the HRI Board. These are the people guiding research, scholarships, and leadership development for our industry, and every one of them has a unique path that brought them here.

First up: Mark Yelanich, HRI Board President and Research Director at Metrolina.

46 years in horticulture and still lighting up when he talks about poinsettias.

Mark joined the HRI Board for a simple reason: he wants to give back to the industry he loves.

Swipe to see what keeps him energized and the advice he has for the next generation.

What plant still makes you smile after all these years?

Gardenias are popular with consumers, but consistent propagation can be difficult.

HRI-funded research led by Dr. Wusheng Liu at NC State University is developing micropropagation systems for elite gardenia cultivars.

The goal: help growers produce uniform liners and scale gardenia production.

Big congratulations to our partners at the Sidney B. Meadows Scholarship Endowment Fund and this year’s 12 scholarship recipients! 🎉

SBMSEF just awarded $30,000 ($2,500 each) to outstanding horticulture students from seven universities across the Southeast. These scholars were selected for their academics, determination, passion for the industry, and financial need. With this year’s awards, the Fund has now given more than $700,000 in support since 1989. Incredible!

This is the fourth year HRI and SBMSEF have teamed up on a shared application, making it easier for students to apply to both programs at once. Their awards are the first of this cycle. Next month, we’ll announce HRI’s 2026 scholarship recipients with more than $60,000 in support for students building careers across the green industry.

Please join us in celebrating:

🌼 Afrifa Amoah-Mensah, University of Florida — Richard J. Hackney Scholarship
🌼 Carly Anderson, University of Florida — Dr. Bryson L. James Scholarship
🌼 Rylee Brown, University of Arkansas
🌼 George Buss, North Carolina State University — Robert L. VanLandingham Scholarship

🌼 Ashley Jackson, University of Florida — Lee C. Howell Scholarship
🌼 Kimberly Mayer, Texas Tech — Sally Smith Scholarship
🌼 Christina Mercado, University of Florida

Bacterial diseases caused by Xanthomonas and Rhodococcus are difficult to manage in ornamental crops.

HRI-funded research led by Dr. Jonathan Jacobs at The Ohio State University is testing biological controls, including bacteriophages and beneficial Bacillus, that specifically target plant pathogens.

The goal: give growers new tools to manage bacterial diseases.
