- Description: A primer on pollen: counts run highest between 5 and 10 a.m. and on dry, hot, windy days. Fewer than 100 of 50,000 tree species and a small share of North America's 1,200 grasses make allergenic pollen, which brings sneezing, itching eyes and congestion.

Less than 100 out of 50,000 kinds of trees produce pollens that cause allergies including oak, birch, hickory, pecan, catalpa. elm, olive, sycamore, walnut, ash, cottonwood, juniper, mesquite, mulberry, acacia, alder, box elder, cypress, and maple.
