In the location's words:

Pack your curiosity, conquer sticks and cobblestones and enter the Kräuterkind greenhouse on the outskirts of Hürth. Everything smells and thrives a little differently than you are used to, not so much in a row. Little plants grow here and there, climbing over the path, bordered by small stones. Plants live here the way they want to live and are lovingly tended and cared for by René and Heike, who run the greenhouse. If you follow the path to the back, you come to a small sandy beach.
