Gran: The Spruce tree
Picea abies, commonly known as the Norway spruce, is
the economically most valuable tree species in Norway. It is
widely planted for its wood, and is the species used as the main Christmas tree
in several cities around the world. It was the first gymnosperm to have its
genome sequenced, and one clone has been measured as 9,560 years old.

Old Tjikko, Sweden |
Old Tjikko is a 9,550 year-old Norway Spruce, located on Fulufjället Mountain of Dalarna province in Sweden. Old Tjikko originally gained fame as the "world's oldest tree." Old Tjikko is, however, a clonal tree that has regenerated new trunks, branches and roots over millennia rather than an individual tree of great age. Old Tjikko is recognized as the oldest living Picea abies and the third oldest known clonal tree.
