A major conservation project is being carried out at the Garden. Working with the National Museum of Wales and the Countryside Council for Wales, the Garden is collecting the seeds of, and propagating, some of Wales’s rarest plants. In a display behind Theatr Botanica you can find a selection of these plants. Here you’ll find one of Britain’s rarest and most critically-endangered trees, the Ley’s Whitebeam (Sorbus leyana) and a hawkweed that only grows naturally on rocks around a single waterfall in the Brecon Beacons.
