Discussion
Gaylussacia brachycera is a dwarf evergreen shrub that forms large, solid-mat, self-sterile colonies, each one appearing to consist of a single clone that may extend over more than one hectare. One colony in Perry County, Pennsylvania, is about 1.5 kilometers wide; it appears to be a single clone that is over 12,000 years old and has been labeled as the oldest living thing in the world.
