The tree is very ornamental with an attractive grey trunk and showy red blossoms. Research has been undertaken at the 成人大片 to tissue culture this hybrid.

Pear Collection

Among the 90 ornamental pear trees in the Waite Arboretum there are several species which are well suited to the Mediterranean climate of Adelaide.

The row of callery pears in the rose garden of the adjacent Urrbrae House Historic Precinct are a breathtaking sight in spring. They were budded from a selection in the Arboretum.

Two species of Pears Pyrus tadshikistanica and Pyrus korshinskyi are on the as endangered in the wild.
