In an ongoing series on hybridizing fruit trees, Syracuse University sculptor
Sam Van Aken’s
Tree of 40 Fruit
is true to its name. Most of the year, it looks pretty ordinary, but in
the spring, the tree blossoms display various tones of pink, crimson,
and white. Then, from July through October, it bears 40 different types
of stone fruit, including almonds, apricots, cherries, nectarines,
peaches, and plums.
The feat is accomplished by grafting together several different
varieties, including native fruit, heirlooms, and antiques, some of
which are centuries-old,
Aken tells Epicurious.
His main source is an orchard at the
New York State Agricultural Experiment Station,
which he leased when he heard the orchard was to be torn down. After
developing a timeline of when each of the 250 varieties blossom in
relation to each other, he would graft a few onto the root structure of a
single tree. When his “working tree” was about two years old, he would
add more varieties onto the tree as separate branches -- a technique
called “chip grafting,”
Science Alert explains.
A sliver that includes a bud is inserted into an incision in the
working tree and then taped in place. After it heals over the winter,
the branch becomes just another normal branch on the tree, to be pruned
as usual.
So far, 16 of these Trees of 40 Fruit have been grown, each taking
about five years. He picked stone fruits because they’ve got a lot of
diversity and they’re inter-compatible. And a bit of garlic and
peppermint repellents keep deer away.
“By grafting these different varieties onto the tree in a certain order I can essentially sculpt how the tree is to blossom,”
he says. “I've been told by people that have [a tree] at their home that it provides the perfect amount and perfect variety of fruit.”
