With their extensive collections, botanical gardens make an important contribution to conserving plant biodiversity. The unpaid exchange of seeds between botanical gardens, university institutions, and similar public research bodies facilitates maintenance and supplementation of plant holdings.

Since the Convention on Biological Diversity, ratified in Rio de Janeiro in 1992, came into force, the process of exchanging seeds has been subject to stricter regulations. The Nagoya Protocol of 2014 further restricted access to genetic resources and sharing thereof. That is why we are a member of an international plant exchange network, IPEN, which makes the process more straightforward.

We issue an annual Index Seminum (seed catalogue). All seeds are the result of open pollination inside the greenhouses and in the open areas. The possibility of hybridisation cannot be excluded.

We do not exchange seeds with private individuals.
