The property (10 acre) was bought by the Fox family in the early 19th century. It was developed as the summer residence for this Quaker family. Robert Were Fox (1789-1877), was an English geologist and natural philosopher. A mining expert, Robert wrote many scientific papers, e.g. on his research on the internal temperature of the earth. He invented navigational equipment, and he also carried out scientific experiments on the acclimatization of plants. He is credited with naturalizing over 300 species of plants. Robert Were Fox formed lasting friendships with A. von Humboldt. He married Maria Barclay and had three children: Anna Maria, Barclay and Caroline.
Unfortunately, the old house became derelict and had to be pulled down. Were it has been, Waldo Trench Fox built the present slate-hung house in 1935. A terrace walk across the front leads past the remains of what were a covered fernery and a grotto and heads to the front of the garden. The extensive collection of sub-tropical trees and shrubs includes original early hybrid rhododendrons, crossed by Barclay Fox and by Mr Smith, one of his head gardeners. 'Penjerrick Cream' is one of the beautiful rhododendrons hybridized in this garden. There are massive specimens of Dicksonia antarctica (tree ferns) some reaching up to five metres high and with a girth of two metres. There are also great clumps of bamboos, many camellias, azaleas and towering trees.
Penjerrick was left to the National Trust by Janet M.K. Fox along with a substantial endowment. Sadly the endowment was not considered to be adequate and this bequest was turned down. The garden is now owned and looked after by her daughter Mrs. Rachel Morin.
