Notes on bee preference for ornamental plants made during the 2007-2009 growing season.
The study was conducted by repeated visits to public garden plantings in Larimer, Denver, Adams, and Cheyenne counties. Gardens were chosen that had large mass plantings of numerous flowering plants so that comparisons could be made and included the Denver Botanic Garden, gardens at Colorado State University (PERC, Flower Demonstration Planting), Welby Gardens, and Cheyenne Botanic Garden. These sites also were chosen because plantings had identification labeling. Plantings were visited between 2 and 12 times between mid-June and mid-September. (2013) Colorado State University.
