The grafting of fruit trees is a very old cultural achievement and, for a large number of fruit species, the only way to preserve and pass on varieties over generations. For example, the concept of the seed bank does not work for apples and pears: the corresponding variety must be preserved alive. For this purpose, the grafting technique was developed, in which, to put it simply, a part of the mother tree is transplanted onto a foreign root. Scion and rootstock grow together and develop into a tree. Pomarium is an ongoing work in which I visually explore this realm between nature and culture.
