Artist Katie Holten loves trees. Back in 2015, she created a secret tree alphabet that she used to write “tree messages”, which later turned into a book. More recently, she partnered with the New York City Parks Department on a whole new collection of tree letters, aimed at bringing more awareness to the trees in our surroundings. They have even decided to plant trees in alphabetical order, based on her choices for the tree alphabet, so that people have a new way of interacting with their environment. No word on whether or not all of the trees will work in this area of the North American climate, but the idea is interesting enough.
