PHELLODENDRON AMURENSE Amur Corktree

1121 Camden, Toledo

Planted: 1966

Site: 6' Tree Lawn

1971 Comments: These plants are upright spreading and well established after only four years in the planting. However, because of the natural spreading habit of growth, they will definitely cause a traffic interference problem in this narrow tree lawn.

Amur Corktree

1997 Comments: The remaining trees are highly variable and many of these are stunted. Sidewalk disruption is not a serious problem. Only one of the plants measured was displacing the sidewalk, and it was the largest of the plants at 18 inches in diameter. This plant has been variable in the Shade Tree Evaluation Plot and in the plantings at the OSU campus as well. The male plants do better since they do not bear fruit or need the energy to mature fruit.

Forty percent of the overall planting survived (17 of 42 trees). The 1997 data in the table are based on four trees.
