About Oak Pollen
English oak, also called pedunculate oak, is the dominant oak of Britain and much of Europe, and it is wind pollinated. In a good year a mature tree releases enormous quantities of pollen, though unlike the coarse grains shed by pines it is too fine to leave a visible yellow dusting on cars. Oak pollen is allergenic, but oak allergy is less common than birch or grass allergy. Many people who react to oak are primarily sensitised to birch, since the two trees belong to the same botanical order and share related allergens.
Oak flowers in mid to late spring, usually April and May, peaking as the new leaves open. Because it overlaps the end of the birch season and the start of the grass season, it can bridge the gap for people with tree pollen allergy and make spring feel like one continuous season.
