Hackfalls Arboretum
Berry originally planned to make maples the main tree collection of his arboretum. However, he soon discovered that the land was better suited to growing oak trees. There are now about 90 different maples, mostly species, but also some hybrids and cultivars. There are 45 species of Mexican oaks, plus several forms and hybrids. Together with specimens from other regions the oaks have reached a total of about 150 different taxa.
