COLUMBUS, Ohio—Researchers at an Ohio State University greenhouse are awaiting a rare second bloom by a rainforest plant known as a corpse flower because of its unpleasant odor.

The university says the nearly 6-foot titan arum is expected to open this week, releasing another round of its rotting-flesh smell a little more than two years after it first flowered.

A second corpse flower opened briefly at the greenhouse last May.

A university spokeswoman tells The Columbus Dispatch ( http://bit.ly/15FLGSU) cultivators are lucky to have three blooms in three years. Each brief bloom attracts visitors hoping to catch a glimpse or a whiff of it.

The plant expected to bloom soon is nicknamed Woody, after Buckeyes football coach Woody Hayes.
