Late Season Pollinator Partners

With autumn’s arrival, Aster and Goldenrod have taken the stage to not only dazzle with pretty flowers, but also offer rich nectar sources for pollinators. These staples of gardens and natural areas are an important late-season stop for bees, butterflies, moths, wasps, and more. You may have noticed the bright golden flowers of Goldenrods in fields and roadsides. Asters’ small daisy-like blooms come in white, blue, lavender, purple and sometimes pink. They pair beautifully together and with the rich fall color of native grasses.

Many people confuse Goldenrod with Ragweed, but Goldenrod is insect pollinated, so their pollen is heavy and falls to the earth. Ragweed is wind pollinated, so its pollen is light, fluffy, and floats in the breeze, much to allergy sufferers distress. The brilliant yellow flowers of Goldenrod offer a striking late-season show and are a larval host for several moths. There are many species native to our area and you can find them mostly in sunny prairie conditions. However, there are a few Goldenrod that light up in the shade.
