Ivanausko was a well known environmental researcher and professor, and the garden is one of the wealthiest sources of genetic resources for apple trees.  One of the types in the garden was developed by Ivanausko himself, and there are other types of apple and pear trees, as well.  The park features a collection of 250-300 types of trees and bushes, including 59 types of coniferous trees.  The apple garden also has one of the most ancient trees in the world -- a biennial gingko tree.
