Species driving Harrisburg’s grass pollen

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

The Arkansas allergy season guide singles out eastern redcedar — a juniper — in late winter, then oak and hickory through spring.
