A tour of Newnham College Gardens with Head Gardener, Charlotte Collis. Set in 17 acres, the main site is divided up into large lawns, wild flower areas, herbaceous borders and formal gardens. Gems include the sunken rose garden, an English Oak (Quercus rober) which was a gift from William Gladstone in 1887, from his Hawarden Estate and Newnham’s own unique collection of bearded irises.
