Larix kaempferi 'Jakobsen's Pyramid' is a narrowly conical to nearly fastigiate, upright form of Japanese larch. Branch terminals all ascend and are clothed with bright green needles. Fall color ranges from yellow to bronze-orange. Prefers full sun in well-drained soil. After 10 years, a mature specimen will measure 14 feet (3.6 m) tall and 3 feet (1 m) wide, an annual growth rate of 16 to 18 inches (35 cm).
This cultivar originated as a seedling selected in 1985 by Arne Vagn Jakobsen Nursery, Glamsbjerg Denmark. The cultivar name almost universally misspelled as, 'Jacobson' or 'Jacobsen' which is quite disrespectful to the originator.
