Just a few blocks from the OK Corral in Tombstone, Ariz., a former hotel and boarding house hides a treasure.
A sign in front says "World's Largest Rosebush," but most people have no sense of its size until they walk through the building and into the backyard.
The bush, a Lady Banksia Rose, was planted in 1885, back when Tombstone was a boomtown for silver mining. The tree officially covers 9,000 square feet, and its gnarled trunk is about 12 feet around. The whole thing is so big that its branches have to be supported on a massive trellis, which spreads out horizontally.
