Interest Areas: production and landscape use of perennials, annuals, and tropicals, greenhouse management, nursery production, public horticulture, hops

I teach courses in ornamental plant production and marketing, herbaceous landscape plants I & 2, and greenhouse management.  My research interests include improving greenhouse and nursery production systems for herbaceous perennials with an emphasis on propagation and rhizosphere management. My extension and outreach work includes Master Gardener training, VCE publications for gardeners and growers, the Garden ProfessorsTM and most recently, a trials hop yard.

Courses: HORT 3345 & 3346 Herbaceous Landscape Plants I & II,  HORT 4324 Greenhouse Management (online),  HORT 4424 Ornamental Plant Production and Marketing

Awards and Honors:
Virginia Nursery and Landscape Association 2012 Professional of the Year
Perennial Plant Association 2008 Academic of the Year
College of Agriculture and Life Sciences 2007 Certificate of Teaching Excellence

Other:  Joel Shuman and I own Bee Berry Farm in Giles County, including three acres of you-pick blueberries. We’re rabid gardeners, and have added about 120 linear yards of mixed border gardens.  We enjoy beekeeping and currently manage seven hives .  We also sell our berries and honey in season at the Blacksburg Farmer’s Market. We have two furry children: Bebe (Basenji mix) and Bunny (silly Whippet) along with a few chickens. We dearly love the Blue Ridge, but tend to run off to the Keys or Caribbean every once in a while.
