The three astonishing elements of this garden are the extraordinary castle built on a heroic scale which acts as a backdrop to the large and varied collection of trees - Douglas Firs, redwoods, Pines, Holm oaks, firs, and native varieties and the collection of rare and tender plants that can be grown here courtesy of the mild climate generated by the Gulf Stream.

In the Walled Garden on the lower slopes below the castle are to found an astonishing variety of tender species, such as Lobster Claw, the florist's bloom, Pot jasmine, Lapageria and Decumaria, even the Cordyline indivisa and Magnolia macrophylla. At the foot of the slopes are huge clumps of giant rhubarb, gunnera, ferns, flax and bamboo standing in front of Holm oaks, Eucalyptus and purple maples.
