at his home at Leura. He wanted his ashes returned to Europe and scattered in the North Sea. His younger son, Ib Sorensen, was also a landscape gardener and carried on the business, finally selling the Sorensen's Nursery in 1988. Legacy Sorensen's main legacies are those of his gardens that survive to this day. He is best known for "Everglades" at Leura but he built over 100 gardens during his career. Unfortunately, some of his gardens have been lost, reduced in size, or neglected. Many of his remaining gardens are at risk from subdivision and other modern urban developments such as road widening. Sorensen's rooftop garden at Feltex House, Sydney, was lost when it was converted to office space in 1954; the original three-storey art deco style building was extended to nine storeys in 1961. A part of his garden "Gleniffer Brae" is now the Wollongong Botanic Garden, although changes made as a public park have masked much of the original garden's design. At "The Braes", the removal of large trees and other changes have altered the microclimate and compromised the aesthetics of the garden. "Invergowrie" retains a large garden by modern standards but due to some sub-division of the land is of reduced extent. A number of his surviving gardens are heritage listed. The garden of the Mount Kiera Scout Camp is one of the best maintained surviving examples of his garden designs but is not heritage listed. Sorensen's other legacies are his techniques for creating gardens and his approach to garden design, both of which were influential. He developed techniques for enhancing the sandy soils of the Blue Mountains, so that these soils could support luxuriant gardens. At "Gleniffer Brae", he transplanted, from the surrounding bushland, several large Illawarra flame trees—reputedly one of the earliest successful transplantings of mature Australian native trees, something still seen as very difficult to do. Sorensen understood the difficulties of creating and maintaining large landscaped gardens in Australia, an extremely dry continent, saying that in Australia the approach should be "don't buy land, buy water". Sorensen's approach to landscape garden design, although based in the European tradition, was influenced by the Australian landscape. He saw the most important elements of gardens as being trees and larger shrubs. He used mainly exotic plants in his Australian gardens, but his terracing, stone walls, and other features were typically less formal and conventional than those of
