POETREE is a funeral urn that evolves over time as a companion through the stages of mourning. The ashes are placed in the urn and are covered with soil. The family takes the urn home and plants a tree in it. When the tree is big enough, it is time to plant the urn in a garden or a park. Eventually the urn, which is made of a biodegradable material and ceramic, will disappear, and only the tree and the ceramic top will remain, just like a gravestone.
