Seeds collection

The showcases in the central hall of the Gymnasium house a historical seeds collection of great scientific value.

The collection consists of approximately 1,500 glass test tubes, hermetically sealed with a cap at the base, which preserve parts of plants with seeds from wild Sicilian species. These precious samples were collected during the 20th century, both within the Botanical Garden and during botanical excursions throughout Sicily, documenting the island's extraordinary flora.

Each test tube is a small genetic archive. The scientific name (genus and species) of the seeds is written on the edge of the cap, and they are preserved in perfect condition thanks to a dry and protected environment.

This collection is of strategic importance as it includes seeds from rare and endemic plants at risk of extinction, such as:

Urtica rupestris: a rock nettle found exclusively in Sicily.

Limonium bocconei: a Sicilian endemic species belonging to the Plumbaginaceae family.

Abies nebrodensis: the Madonian fir, one of the most endangered species in Europe, whose conservation is an international priority.

Seed collections, or “germplasm banks”, are a fundamental part of conservation. Offering a valuable genetic heritage, they are essential for scientific research and reintroduction projects, helping to safeguard plant biodiversity and combat species loss.

The Botanical Garden of Palermo has a seed bank, that is a collection of seeds for study and conservation purposes. The institution publishes the Index Seminum annually, a catalogue that allows the exchange of seeds with other botanical gardens and research institutes around the world. This activity not only keeps its scientific tradition alive, but also reinforces the Garden's commitment to the global protection of plant heritage.
