2000 OSU/OFA POINSETTIA
TRIAL RESULTS

by Dr. Claudio Pasian (Ohio State University) and
Dr. Steve Carver (Ohio Florists' Association)


In this issue, we present the results of the five grower evaluations conducted 16, 17, 20, and 21, November, 2000. The growers who grew the plants and generously hosted the open houses were: Lakewood Greenhouse in Toledo, Dill's Greenhouse in Groveport (Columbus), Barco's in Medina, Bostdorff Greenhouse Acres in Bowling Green, and Diefenbacher Greenhouse in Cincinnati. Cuttings were donated by four breeders/suppliers: Dummen USA Inc, Paul Ecke Ranch, Fischer USA Inc, and Oglevee Ltd. Each grower followed its own cultural procedures. Planting and pinching were done during a four day window.

We asked growers to evaluate each group of plants (cultivars) using a scale 1 - 5
(1 = like the least; 5 = like the most). This evaluation is presented in Table 1. It is interesting to note how some cultivars fare well, or do poorly regardless of who grew them. Compare this table with Table 1 in last month's issue of this newsletter. Worth noticing are differences between what consumers like and would by vs. what growers like. This year we asked growers to pretend for a moment they were regular customers instead of growers and to select no more than three cultivars they would buy assuming the price was right. Their selections are shown in Table 2. We are very thankful to Monica Kmetz-Gonzalez and Shawn Shay for their help with this project.
