High-Rise Lawn

They haven't figured out how to mow it yet, but architects and federal officials plan one of the world's most extensive vertical gardens in downtown Portland — what amounts to a series of 250-foot-tall trellises designed to shade the west side of an 18-story office building.

The west wall is 150 feet long, making the expanse to be shaded about three-quarters the size of an NFL playing field. The work is part of a $135 million remodeling, with most of the money from federal stimulus funds.
