Reservations are due by Thursday for an annual dinner and auction with the University of Tennessee Arboretum Society.

The Nov. 13 dinner will feature keynote speaker Andy Pulte, radio host on WNOX and University of Tennessee Department of Plant Sciences gardening expert, a press release said.

The dinner and silent auction start at 6 p.m. Nov. 13 at The Elks Club, 684 Emory Valley Road in Oak Ridge. The public is invited, and the cost is $25 per person, the press release said.

The release said Pulte is one of the hosts of “The Garden Guy” with Sue Hamilton on WNOX’s “Garden Talk,” a weekly radio show on from 8 a.m. to 9 .m. Saturdays.

His topic for the UT Arboretum Society dinner and auction is “Backgrounds and Borders Design Theory and New Plants for Everyone.”

“Paying attention to the specific emotions plant colors evoke is important,” Pulte said in the release. “Colors can be beautiful in peaceful, happy, relaxing, invigorating and even sad ways. The colors you ultimately choose for a garden should reflect the mood you want to express.”

He will also discuss using a set of newer or unusual plants you should consider adding to your landscape this year.

The press release said Pulte grew up in the nursery industry in Grand Island, Neb. He received his bachelor’s degree in horticulture from the University of Nebraska and a master’s degree from the University of Tennessee in the area of public horticulture.

He has worked at the National Arbor Day Foundation in the education department and the Henry Doorly Zoo in Omaha, Neb. He contributes to several gardening publications, speaks regularly to diverse groups, and travels extensively to feed his passion for people and plants, the press release said.

The Nov. 13 dinner and auction will begin at 6 p.m. with a social hour (cash bar) and silent auction followed by a buffet dinner at 7 p.m., then a brief business meeting and Pulte’s presentation. Silent actions items include fine crafts, gifts certificates, art, wine and accessories, hard tools, and more, the release said.
