Canna Indica by Ching Wen Tsai
The work, Canna Indica, is inspired from the flower named the same that commonly grow in tropical regions. The seeds of Canna Indica are solid and hard enough that were used to replace bullets when soldiers ran out them in 19th century. The seeds could survive and flourished after shooting. The way they expand is to burst open seed pods and scatter seeds as far as they can.
