What types of pollen cause hay fever?
top of page ^
Tree, grass and weed pollens contain hay fever allergens. These have small, insignificant flowers which do not attract insects. Generally, the brightly coloured flowers of insect-pollinated garden plants like roses or wild plants, including poppies, do not cause hay fever. The tiny grains of pollen (ranging in size from 0.25 to 100 microns) readily become airborne and are capable of travelling through the air many miles from their source.

Check the lists below to see which pollens might be causing your hay fever:

Trees: Ash
Birch
Cedar
Chestnut
Cypress
Elder
Elm
Hazel
Oak
Poplar
Sycamore
Walnut
Willow
Grass: Dogstail
Fescue
Foxtail
Meadow
Oat
Rye
Timothy
Vernal
Weeds: Dock
Mugwort
Nettle
Plantain
Ragweed
Sorrel
Wall pellitory


Grass releases pollen from around 7 in the morning and later in the day if the ground is damp. Some grass species don not release their pollen until the afternoon.

Birch trees release their pollen between noon and 6pm.
