In the succulent house, plants from the dry-hot areas of the earth thrive. Latin "succus" means juice. Succulents are therefore plants that have a particularly high water content. The succulent house is divided into two parts:
In the front part: plants from the Americas, which are mostly, but not exclusively, cacti. The large Echinocactus grusonii specimens at the entrance are well over 100 years old.
In the rear part: plants from the Old World (Eur-Asia and especially Africa), which are a colorful mixture of representatives of different plant families that may superficially look like cacti, but they are completely unrelated. The rear part of the succulent house is home to island endemics, especially from the Canary Islands, including many succulents.
