As regional context only — not as today’s readings — in the Midwest & Great Lakes pattern, the plants that typically shape this city’s year are spring trees, late-spring and summer grasses, and late-summer and autumn ragweed.

The Illinois allergy season guide singles out the classic tree, grass and ragweed sequence at full strength, with mold as a Chicago co-headliner.
