Owned by Michael and Anne Heseltine, Thenford Arboretum is set in over 70 acres and features a collection of more than 3,000 different trees and shrubs together with extensive herbaceous borders, lakes, a walled garden, sculpture garden, avenues, a rose garden and a rockery.

The snowdrops are a particular attraction and in June 2023 the collection was awarded National Collection status by Plant Heritage.
