The garden is regarded as one of the significant gardens of Mount Tomah, with an entry of it’s own in the lavishly illustrated book “A Passion for Place” (2010) , describing the finest gardens of Mount Wilson, Mount Irvine & Mount Tomah.

Total area 12.88 ha / 31.82 acres

The garden is on level spur of the mountain with deep, rich, reddish basaltic soil. The climate is cool but mild, with relief from the summer heat experienced in the Hawkesbury valley towns.

The garden was established around 40 years ago & contains a remarkable collection of trees and shrubs. Growth has been rapid, owing to both fertile soil and high annual rainfall. There are over 50 mature conifers, including pines, cedars, firs, spruces, junipers and redwoods; numerous deciduous trees such as maples (12 species), flowering cherries, magnolias and ashes; and over 60 varieties of rhododendron with flowering times ranging from August to December. Among notable trees are a vigourous 30 year-old Monkey-puzzle tree, and a magnificent 22 metre tall specimen of the very rare Taiwania just inside the entrance gate.

Area fenced as garden is approx. 1.7 ha / 4.2 acres. Most of the remainder is undisturbed bushland of high scenic and conservation value. About 100 m west of the garden fence the land drops over a 20 m sandstone cliff into wilderness bordering Blue Mountains National Park. The south-west boundary is on Mill Creek, 160 m lower in elevation than the north-eastern end of the land.
