No, Jonathan Green grass seed varieties are not genetically modified.

The advancements in our varieties are obtained by traditional cross-hybridization, otherwise known as cross-breeding. This is accomplished by selecting parent plants for their specific traits, then transferring the pollen from one plant to the pistillate parts of the other plant, creating a new generation of plants with characteristics of the parent plants.

Genetically modified organisms (GMOs) are obtained when a single gene, or a small set of genes, from one plant, are transferred into a new genetic background of another plant.
