Until 1 March 2010. The Botanic Garden at the University of Oxford offers visitors a series of events over winter, including an exhibition of fibre-inspired artworks which promotes Fairtrade clothes. This collaborative event has been organised between students from the Ruskin School of Drawing and Fine Art and the ethical fashion outlet 'Trading for Development'. In addition, a family-friendly fibre afternoon is planned which includes a celebratory 'knit-off'. Impressive glass houses can be found within the walled gardens, while outside the walls can be found the water garden and rock garden.
