Abstract
Fueled by increasing interest in home gardening, this trial was established to evaluate seven cultivars on hardiness, growth habit, and overall appearance. Three specimens of Emerald, Holmstrup, Woodwardii, Elegantissima, Berckman’s Golden Biota, Pyramidalis, and George Washington were planted at the Muscatine Arboretum, Muscatine, IA, in June 2001. The planting site was on a knoll allowing full sun exposure and air movement. The soil is a moderately well drained, fertile clay loam.Roundup herbicide, woodchip mulching, and hand pulling controlled weeds. Plants were not pruned to observe natural growth habit.
