WEST LAFAYETTE, Ind. — The second annual Purdue National Poinsettia Trials Consumer Open House will take place from 1-5 p.m. Dec. 6 at the Purdue University horticulture greenhouse.

Poinsettia growers, breeders and consumers from across the country will be able to assess more than 95 different plants of various colors, shapes and sizes at Purdue and from similar events at the University of Florida and North Carolina State University. The open houses include poinsettias trees, plants grown in degradable or compostable pots, and experimental and novelty cultivars.

Poinsettias will not be for sale, but there will be several drawings to win some of the traditional and novelty cultivars, which come from poinsettia breeders Ecke, Dummen, GroLink, Syngenta and Selecta, said Roberto Lopez, assistant professor and floriculture Extension specialist.

Attendees will be asked to fill out a survey to enter to win one of 25 poinsettias. Lopez said the survey will show consumer preferences to help breeders and growers determine what kinds of poinsettias U.S. consumers want.

“We want to know their thoughts on new colors, novelty plants and potential new flower crops,” Lopez said.

Purdue Extension also will provide Extension publications on caring for poinsettias during and after the holidays.

The greenhouse is located at the corner of Marsteller and Harrison streets on Purdue's West Lafayette campus.

The Indiana Flower Growers Association, Purdue Department of Horticulture and Landscape Architecture, Purdue Extension, Dummen, GroLink, Paul Ecke Ranch, Selecta First Class, Syngenta Flowers, and the University of Connecticut sponsor the open house.

WEST LAFAYETTE, Ind. — A plan has taken root to turn Purdue University’s West Lafayette campus into a garden spot.

The Purdue Arboretum project officially launched during last weekend’s Spring Fest. Spring Fest visitors were invited to learn about the arboretum at the E.C. Stevenson Pavilion, located behind the Horticulture Building and south of the Agricultural Mall.

Viburnum cassinoides, or Witherod Viburnum, is one of the hardy viburnum species that may be added to the special collection.

“The arboretum project is intended to increase the number of woody plant species on campus for learning, engagement and discovery purposes,” said Matt Jenks, Purdue professor of horticulture and the arboretum director.

Jenks said the arboretum idea has been around for a few years but began to take shape this past fall when a campus committee was formed.

“One of the things that got me started on this was the decline in the diversity of plant material on campus for use in the woody plants class that I teach,” Jenks said.

“We plan to focus the arboretum collection on superior landscape plants for the Midwest. In addition, we want to create two special collections of all the hardy maples and hardy viburnums of the world.”

A viburnum is a shrub or tree.

The Purdue Arboretum will meet the arboretum guidelines of the American Public Gardens Association.

“Among other things, an arboretum needs to be open to the public and have signage to provide interpretation of the plant material,” Jenks said.

Most of the guideline requirements can be met with existing resources, “but we would love to see the arboretum expand from where it is now to become a significant collection of woody plants and special gardens,” Jenks said.

The university’s grounds department will play a major role in operating the arboretum, he said.

“We hope the arboretum promotes environmental sustainability and makes the campus a much more beautiful place,” Jenks said.
