These trees are the largest trees in Ridge Park and likely to be the largest in the City of Unley. It has been described as the oldest tree in the City of Unley. The trees are River Red Gums and are in excellent condition given their age of between 300 and 350 years old.

A plaque next to one of the trees reads: Tree Protection _ This River Red Gum has been growing on this site since the mid to late 17th century making it approximately 300 _ 350 years old. At the time of Captain Cooks landing in Australia this tree was already approximately 100 years old and would have been standing approximately 20 metres high. To assist the tree continue in its good health so that future generations can benefit from it as we have, the City of Unley has installed protective fencing.

Ridge Park is a significant open space within the council area. This reserve in the eastern extremity of the municipality, through which the Glen Osmond Creek flowed intermittently, was opened in 1906. The original Ridge Park was a homestead established by Robert Miller after he and William Sanders each bought part of the land in 1843. Miller sold his part to Captain Simpson who allowed the public to use his grounds. After his death residential subdivision began and so a community committee raised funds to purchase some of the land. Ridge Park Recreation Ground was opened and a Trust established in 1907. After long negotiations the park was transferred to Unley Council in 1927. The park is well used today by the community and the three trees are along the creek and are landmarks in the park. The Council describes that Ridge Park is defined by its large trees.
