Demand for this kind of seed is likely to continue to rise in future.

The reason is that, from 2020, only indigenous seed of this kind can be used in Germany for recultivating grasslands in open countryside. Until recently there has simply been insufficient data to provide a well-informed answer to this question.

In fact, every species has many variants which have adapted to suit the specific challenges of their environment.

Some might, for example, withstand drought better than others, while others might survive harsh winters or thrive in poor soils.

"It may be cheaper to buy this seed abroad," he explained, "but the plants may then have adapted to suit conditions somewhere like New Zealand, for example, and not German regions such as Bavaria or Brandenburg." For this reason, many ecologists are speaking out in favour of also using seed from locally grown grassland plants.

Scientists from the University of Hanover have also already developed a concept in which Germany is divided up into 22 areas of origin, using different geographical criteria.

The researchers also discovered that the individual variants also flower at different times.

Brown knapweed of different origins flowered up to 17 days apart.

In the case of some species such as white bedstraw, the researchers also discovered a definite trend: the genetic differences become ever greater, the further the areas of origin are apart, and the more their climates differ.

According to Durka, this is a clear indicator that these plants have adapted to their regional conditions.

The extent of the actual genetic differences between members of the same species from different areas of origin was simply unknown.

And that's without even mentioning whether such differences actually affect how the plants flourish.

These areas of origin are then grouped in eight production zones.
