Plant Power (in partnership with the James Hutton Institute) & Family Picnic & a Play in the Botanic Gardens. Come along to an informal gathering, with free entry to the Botanic Gardens for the afternoon. Bring your picnic hamper and take the chance to relax at the end of such an exciting weekend! There will also be a special performance of the Four Marys play - four iconic Marys – Slessor, Brooksbank, Walker and Baxter – each helped the city in their different ways. Lots of fun activities will be taking place throughout the day, including music, birds of prey and badge making.
