And then those ferns: male fern, female fern (which don’t get along with each other, because they are two different plant species), soft needle fern, bracken fern, tongue fern, iron fern… the list goes on. “We are really proud that we have created this fern valley. You will hardly find something like this anywhere else in the Netherlands.”
