The Choice installation by environmental artist Kerry Morrison and botanist Alicia Prowse highlights the human factor in changing the rural landscape and challenges the general view of plants as mere vegetables.

A vending machine dispenses seeds of Himalayan Balsam, a non-native plant that meets demands for new and exotic garden plants but is also regarded as a threat to native British flora.

People using the machine are given information about the balsam, its place within Britain’s landscape, and the human factors responsible for its presence.

Visitors are then asked to choose whether or not to plant the seeds – they are holding a future in their hands.

The installation can be seen at Cornerhouse in Manchester (UK), till January 9.
