Which Plants Make the Most Pollen?

Blame it on trees, grasses, and weeds. They produce small, lightweight pollen that can travel in the air for miles. The biggest offenders:

  • Trees like oak, ash, elm, birch, maple, alder, and hazel, as well as hickory, pecan, and box and mountain cedar. Evergreen juniper, cedar, cypress, and sequoia trees are also likely to cause allergy symptoms.
  • Grasses like Timothy grass, Kentucky blue grass, Johnson grass, Bermuda grass, redtop grass, orchard grass, sweet vernal grass, perennial rye, salt grass, velvet grass, and fescue.
  • Weeds like ragweed, sagebrush, redroot pigweed, lamb's quarters, goosefoot, tumbleweed (Russian thistle), and English plantain.
