Rye grows on sandy and lighter soils, as well as in moist and cooler regions. The stalks grow to about 65 to 200 centimeters long. The stem and leaves have a silvery green color.

The rye belongs to the family of sweet grasses. In Europe, it is mainly used as animal feed. Processed rye is found in various products such as flour, in the form of flakes, meal and semolina or even in alcohol. Rye allergens belong to the group of cereal pollens and are therefore one of the most important allergens.

Pollen season and harvesting time

During it´s pollen season, rye bears slightly overhanging ears. The pollen season is between May and July. Rye is usually harvested from the end of July to mid-August.

Possible cross-reactions

Rye pollen is closely related to grain and grass pollen. It is therefore not uncommon for allergy sufferers to be allergic to these pollens as well.
