A new and distinct variety of Quercus virginiana tree named 'K-1' is disclosed. It is characterized by having a dense, upright naturally columnar habit, by being easily trained to a single leader, and by having small lateral branches leaving the main trunk at 45 degree angles and arching upward to produce a very compact and dense canopy. Its leaves are not shed noticeably in the spring, giving the appearance of an evergreen Live Oak.
