Sir Harold Hillier Gardens (formerly known as the Hillier Arboretum) hold one of the greatest collections of hardy trees and shrubs in the world. Started by the late Sir Harold Hillier in 1953 and given in trust to Hampshire County Council in 1977, the Gardens now extend to 180 acres.

Within this unique collection of more than 42,000 plants (12,500 different types), visitors will find much of interest throughout the year.
