Name this tree of the week:

zelcova
This 20-footer grew fast on the Friends of Trees' lot. (FOT file)

A native of Japan, this disease-resistant deciduous has small, triangular fruit. It is known as a substitute for the American Elm, is a fast-grower, and can fit in a six to eight-foot planting strip without power lines.

Bonus clue: name rhymes with Navratilova. Submit your guess below in the comment forum!
