The art of topiary seeks to control the growth of the plant and to form from it the desired shapes. Also to control the extent of growth annually in order to maintain those shapes once they have been achieved. The practice is to increase the surface density of the pieces and a strong and relatively rigid structure beneath. In ‘Anastasie Fătu’ Botanical Garden of Iaşi, children, students and educators worked together to explore environmental issues using action-oriented inquiry. An interdisciplinary approach to curriculum helped children and students to understand specifi c ecological conditions and enabled them to learn about the complexities of surrounding contemporary ecological art. Students and biologist learned about topiary design, construction and how maintenance is an ongoing process.
