Seeds of the Garden plants are collected for our own needs and for exchange with other botanical gardens. We exchange seed indices (Index seminum ) with 293 gardens annually, which amounts to about 18% of all botanical gardens in the world. It is a matter of a well established exchange of seeds which, free of charge, serves various research and educational purposes. 

The Garden possesses a seed bank of the plants grown in the Garden and we have started working on a seed bank of plants from natural habitats.
