Pollinator gardens

URBANA -- Bumblebees, honey bees, butterflies, moths, hummingbirds, and some other birds are essential for plant pollination, which must take place for fruit to form. University of Illinois Extension horticulture educator Kelly Allsup encourages gardeners to choose plants and herbs for next spring's garden that will attract these pollinators.

Pollinator gardens typically contain native perennials such as the aromatic anise hyssop (Agastache foeniculum), drought-tolerant coreopsis (Coreopsis grandiflora), spring-blooming wild indigo (Baptisia australis), and the white flowering foxglove penstemon (Penstemon digitalis). Native insects have evolved with native plants and prefer them to non-native ornamental plants.

Pollinator gardens also incorporate flowering herbs such as lavender, marjoram, oregano, thyme, chives, fennel, and parsley. Their aroma and consistent flowering make them attractive to pollinators and are sources of nectar and pollen for beneficial insects and wasps.

"Provide pollen and nectar sources all throughout the growing season by planting perennials, herbs, and ornamentals that flower at different times," said Allsup.

Plant flowers of different colors and contrasting shapes in the pollinator garden. Butterflies are attracted to orange, red, and yellow and need a landing platform. Bees are attracted to blue, yellow, and white and can see ultraviolet markings, the nectar guides, leading them to the source of nectar and pollen. Hummingbirds prefer plants with long tubular flowers in shades of red.

Allsup urges gardeners to include a decorative bird bath to serve as a source of water for pollinators, birds, and other wildlife.

She warns that chemical pesticides should not be used on pollinator gardens and surrounding areas. Accept some insect damage, or use organic pesticides.
