MANHEIM, Pa. — The year 2018 was a challenging one for growers of annual and perennial plants. This was no different at the Penn State Flower Trials, and by the first week of October 2018, the Southeast Agricultural Research and Extension Center in Manheim had received 26 inches of rainfall above the annual average, with almost three months left to go in the year.

These conditions challenged growers throughout the state as well as at the Penn State Experiment Station.


Plant diseases were more abundant in the 2018 growing season, and it was difficult to keep container fertility levels up to target ranges.

With the unusual weather, many plants that had done well in previous seasons were not up to their typical past performance. This was not so much due to breeding and genetics, but rather a climatological repercussion occurring with the overabundant rainfall.

In one event, there was more than 7 inches in two hours, and another storm dropped just over 11 inches.

Twenty-two entries received a perfect score of (five out of five) for the 2018 growing season, out of the 999 total entries tested. There were also 43 entries that received a final score of 4.9 out of 5.0.
