Ornamental Plant Cultivar Choice Influences Pollinator Visitation

We conducted visual observations and sampled via sweep nets to assess the potential of flowering ornamentals to act as a conservation resource for pollinators.

Agastache (Pursh) Kuntze ‘Black Adder’ and Celosia spicata L. were the most frequently visited by pollinators among 74 plant taxa.

We found variation in bee visitation to 40 cultivars evaluated in a 2-yr study in north Georgia. The cultivars ‘Seminole’ and ‘Victor’ were the two most often visited by all bees, including honey bees, carpenter bees, and several small bee species. ‘Apalachee’, however, was the cultivar most frequently visited by bumblebees.

Landscape Factors Affect Pollinator Occurrence in Residential Landscape Settings

During 2019 49 species of bees and 17 species of butterflies were captured in pan traps in residential settings. We found significant differences in bee assemblages among 3 predominant land cover types: Forest, Urban/development and agriculture. 14-15 species of bees accounted for 90% of the differences between the 3 cover types.
