Trial sites put plants to the test

Weather conditions across the country ran the gamut this year from normal temperature and precipitation levels to late-spring freezes and excessive rainfall to unusually hot, dry summer conditions. Here are reports from 37 sites in the United States and Canada that highlight species and cultivars that performed well. Trial managers made these choices in mid- to late-July.

CANADA

Holes Greenhouses & Gardens Ltd., St. Albert, Alberta

The trial gardens at Holes Greenhouses were planted in late May, which is later than years past because of a late, cool spring. May was cool and cloudy. June had a brief period of hot weather, early in the month, followed by cool, rainy conditions and some hail. The night temperatures in June were well below seasonal averages. The weather finally warmed up in early July which brought above-normal temperatures with lots of humidity and regular precipitation overnight. Favorable weather conditions helped fuel an aphid problem.

It was dry when the trials were planted in early June, which was followed by a few weeks of high temperatures. Temperatures turned moderate -- between 70° and 80° -- by the end of July.

Cincinnati Zoo & Botanical Garden, Cincinnati

These trials are a cooperative effort between the Ohio State University Hamilton County Cooperative Extension, the Cincinnati Flower Growers Association and the Cincinnati Zoo and Botanical Garden. The trials consist of about 200 varieties both in the ground and in containers.

The weather started out dry and unusually hot in May and June but cooled down with adequate rainfall by the end of July. Celosia ‘Smart Look Red’ experienced some Phytophthora root and stem rot and the peacocks damaged some of the scaevola and cleome.
