GOLDENROD GETS THE BLAME.
RAGWEED IS THE CULPRIT.
Goldenrod (Solidago spp.): bright yellow, insect-pollinated, and an important late-season food source for pollinators. Goldenrod pollen is relatively heavy, sticky, and adapted for insect transport. Goldenrod is not primarily wind-pollinated. Its pollen must be picked up on the bodies of visiting insects and moved from flower to flower. Because it is too heavy and sticky to blow freely through the air, it is not floating around in clouds waiting to cause widespread allergy symptoms.
Ragweed (Ambrosia spp.): small green flowers, wind-pollinated, and a major source of airborne fall allergy pollen.
Every fall, goldenrod gets blamed for the sneezing and allergies that arrive with the season. But goldenrod is actually an important resource for pollinators when many summer flowers are winding down. 🌼🐝
Ohio is home to roughly 25 native species of goldenrod, providing nectar and pollen for bees, butterflies, flies, beetles, wasps, and many other insects. You'll see it blooming now in gardens, disturbed habitats, along the roadside and woodland edges.
So what's causing all the sneezing?
Ragweed!
Ragweed blooms around the same time as goldenrod, but its small, green flowers are easy to overlook. Unlike goldenrod, ragweed is wind-pollinated, releasing abundant, lightweight pollen into the air.
Goldenrod is visible. Ragweed is airborne.
Next time you see a field of goldenrod glowing yellow in the fall, don't blame it for your allergies - take a closer look at how much life it's supporting instead. 🌼
