Getting to the root of spring allergies
For allergy sufferers, spring often brings sniffling, sneezing and watery eyes, said University of Illinois Extension horticulture educator Rhonda Ferree.
“One culprit is pollen from flowers of trees, shrubs, grasses and weeds,” explained Ferree. “Though most of these bloom for just a short period, something is almost always blooming. In early spring, it’s the trees and shrubs. In summer the main pollen source is flowering grasses. In late summer and fall, weedy plants from roadsides are the problem.”
Pollen is an important part of plant reproduction and must be moved around from flower to flower. Showy flowers attract insects such as bees, which help pollinate the flowers, but not all plants use insects. Most plants that cause allergies use wind to spread their pollen.
