The largest and oldest rose bush in the world is a
Lady Banks Rose. It is found in Tombstone, Arizona
where the rose bush covers 8,000 square feet and is supported
by a series of fences and posts. That rose was planted in the
late 1800's and is still thriving to this day,
blooming just in the spring.
