The 2013 season is over and the results of our annual flower trials have been compiled. This year we conducted evaluations on 182 flower cultivars in our general trial and an additional 85 cultivars within our CFGW (Commercial Flower Growers of Wisconsin) trial. Starting in July we conducted evaluations a total of three times, approximately one month apart. This data is used by seed companies, commercial greenhouse growers, and the public to better select varieties that will succeed in our region of the world. We thank all participants including student evaluators Deanna Delfosse and Rachel Peters.
The study of organic fungicides on powdery mildew went very well this year. In spite of the difficult weather conditions this year posed, the plants grew well and we were able to obtain very clear data. This years data was consistent with the data from 2011 which shows that we are the right track in determining the effectiveness of organic fungicides on powdery mildew that the cut-flower growers will be able to utilize. Along with this trial, there was a new element to this study. We looked at the effectiveness of cranberry leaves as a mulch. With two depths tested, along with a control, we were also able to see very clear results in how well cranberry leaves are able to suppress the growth of both grass-type weeds and broadleaf weeds. This study showed great promise this year and we are excited to continue to watch the results in 2013.
This year our flower trials included 388 cultivars of annual flowers. Three times during the season (Jul. 7, Aug. 6, and Sept. 10) we make careful evaluations of each. We look to evaluate the seed companies claims about the plant. We note consistency of size, habit, flowering, and color. We also note disease issues, insect pressure, and weather tolerance.Our evaluations are compiled with weather data and provided to the individual companies as well as the public.
In addition to our general trials we conduct a specific trial for the CFGW (Commercial Flower Growers of Wisconsin). With their financial support we trial up to 130 cultivars of one or two types of flowers a year. This year we conducted evaluations on sun loving impatiens and osteospermum. The goal of the trial is to provide this industry group a better understanding of which varieties thrive in conditions here in Wisconsin. This data helps Wisconsin growers provide consumers with varities better suited to our climate and soils.

On July 26 soldiers from the Wisconsin Army National Guard received training at the University Display Gardens. The instruction focused on growing techniques for grapes, apples, and vegetable crops. The training was part of a week long series ‘Agriculture 101’ that was coordinated by the UW Babcock institute. The soldiers were given an overview of many agricultural topics to help prepare them for their service dealing with civilian farmers abroad.
This summer we trial hundreds of annual flowers. Those annuals that we evaluated are listed on the two sheets you will find below. The sheet labeled Commercial Flower Growers is the rating for over 50 different petunias that have been produced through vegetative propagation rather than seed.
We trialed these petunias for the commercial growers in Wisconsin so that they could could determine the best petunias to sell for the 2012 growing season. Many of the petunias preformed very well and given our highest rating….5.
We also trialed seed propagated annual flowers for many different companies. The results are listed as Annual Flower Evaluations. Enjoy reading the evaluations and we hope the evaluations help you choose next years summer annuals.

Are you receiving new seed catalogs? Are you already itching to visit your local greenhouse to see what’s new in annual flowers for 2011? Before you begin to make your list, check out the evaluations of all the annual flowers completed by the University Display Garden’s student interns and Master Gardener Volunteers. Links found at bottom of page.
Two evaluations are completed each summer for our annual flower trials. You will find those links below. One evaluation is for the date 8/5/2010 and the later is for 8/31/2010. In addition to our annual flower trial, we trialed over 100 varieties of annual geraniums. You will find that link below,also.
This year, due to the tremendous rain and high humidity, many of the selections performed well until about mid-July. Root rot and foliar disease resulted in damage to numerous varieties. Please review each evaluation so you may have a complete overview of each varieties performance throughout the summer.
