Reiman Gardens is the 17-acre botanic gardens of Iowa State University in Ames, Iowa. Weather was as always one of the biggest challenges. Winter ran long and Ames saw snow through the middle of April. After roughly two weeks of spring temperatures, the gardens consistently saw high-80s and mid-90s with lots of rain.
Here’s what Trial Manager Jessie Liebenguth said about the Iowa State University field trials:
It was a challenge to get plants in the ground and keep them watered well in the heat or from drowning on a day when we received over 5 inches of rain in one morning. The majority of our approximately 200 trial entries were from either All-America Selections, for which Reiman Gardens hosts trials in Ornamental Seed, Edibles, and Perennials, as well as American Garden Rose Selections.
It was a very difficult year for roses and tomatoes, especially with irregular watering and varying temperatures all growing season. Conditions were perfect for a prolonged Japanese beetle infestation, but very few hornworms were spotted — a relief for Reiman’s 30-plus tomato entries and comparison plantings. One in-house trial that was a pleasure to carry out was a sampling of various uncommon salvias; the majority will be left in-ground over the winter to see what may be beneficial to introduce into our plant palette.
Because Reiman Gardens participates in many blind trials, we don’t always know what cultivars were successful in time for this report. Top performers include:
Canna ‘South Pacific Orange’
Capsicum ‘Roulette’ habanero
Trial tronchuda-style kale
Trial yellow sweet pepper
Trial mini cucumber
Coreopsis ‘Golden Globe Compact’ tickseed
Salvia nutans (nodding sage)
Best of Show
Salvia nutans (This variety was a huge butterfly magnet with great style.)
Zinnia ‘Queeny Lime Orange’
Capsicum ‘Onyx Red’
Capsicum ‘Roulette’ habanero – These peppers have the flavor of a habanero, but typically none of the heat (although there can be a hot one here and there).
Trial mini cucumber – This was the longest producing cuke in trials. It had a light flavor.
Capsicum ‘Onyx Red’ – great size, very uniform, beautiful fruit
