The Alister Clark Memorial Rose Garden is the only complete collection in Australia of the surviving roses of "the great Australian rose breeder, Alister Clark" (1864–1949). It is situated near "Glenara", his old house and garden in Bulla, Victoria, 10 km NW of Melbourne Airport. There are at least 150 named roses by Alister Clark and many more plausibly attributed to him. Of these 83 are known to survive, though the authenticity of some is disputed and another eight only survive outside Australia. The garden is maintained by volunteers coordinated by the Hume City Council.
