New Pollinator Publication (07/30/20)

Pollinators are in rapid decline worldwide.

Pollinators are in rapid decline worldwide. Many factors have been attributed to this decline including include habitat loss, parasitic pests, pesticides, diseases, and climate change. However, homeowners can help pollinators’ survive by planting perennial flowers in their backyards, providing nesting habitat for bees, and using less toxic pesticides only when needed.

Our new pollinator extension publication, Pollinator Preferences for Selected Aster, False Indigo, Bee Balm and Sedum Flowers in North Dakota H1962, will help gardeners determine which perennial flowers to plant that attract and nourish pollinators such as wild bees, bumble bees, honey bees, syrphid flies and butterflies. Eight perennial native species and 20 perennial ornamental cultivars were observed for their ability to attract pollinators at two locations in southeastern North Dakota. The genera of perennial flowers tested were Baptisia (wild indigo, false indigo), Hylotelephium (tall sedum), Monarda (bee balm), and Symphyotrichum (aster). Check out our results on which native species or ornamental cultivar was preferred by pollinators.
