The grounds of the house were particularly rich in ferns, mosses, liverworts, and lichens. The lichens grow in profusion on the old walls, slate roofing tiles and tree bark, especially of the older specimen trees, such as the pedunculate oak ("Quercus robur"), sessile oak ("Quercus petraea"), horse-chestnuts and the copper beeches ("Fagus sylvatica cuprea"). "Xanthoria parietina" was a common lichen growth on the boiler house tiles. The giant sequoia ("Sequoiadendron giganteum") has many small depressions in its bark made by treecreepers.
