Housed in the National Herbarium at Glasnevin is a substantial collection of wood, fruits, seeds, bark, as well as plant-derived products or artifacts. This collection was formerly housed at the National Museum in Kildare Street until 1970, when it was moved to the National Botanic Gardens.

Material is gradually being accessioned and catalogued, and to date, some 8,000 items have now been databased. It is hoped that a catalogue will be available on-line on the near future.

From time to time exhibits of this material are on display in the Visitor Centre of the Botanc Gardens. Previous exhibits have included items associated with the Irish Patriot Roger Casement, who donated plant material from the then Belgian Congo.

In August 2003 an exhibit on Seeds was displayed.
