Sam Van Aken, an artist and professor at Syracuse University, uses
"chip grafting" to create trees that each bear 40 different varieties
of stone fruits, or fruits with pits. The grafting process involves slicing a
bit of a branch with a bud from a tree of one of the varieties and inserting it
into a slit in a branch on the "working tree," then wrapping the
wound with tape until it heals and the bud starts to grow into a new branch.
Over several years he adds slices of branches from other varieties to the
working tree. In the spring the "Tree of 40 Fruit" has blossoms in
many hues of pink and purple, and in the summer it begins to bear the fruits in
sequence—Van Aken says it's both a work of art and a time line of the
varieties' blossoming and fruiting. He's created more than a dozen of the trees
that have been planted at sites such as museums around the U.S., which he sees
as a way to spread diversity on a small scale.
