Larix decidua 'Lanark' is a broad, oval, upright form of European larch with bright-green foliage held on short stems. After 10 years of growth a mature specimen will measure 3 feet (1 m) tall and wide, an average growth rate of 3 to 4 inches (7.5 - 10 cm).
This cultivar originated as a witch's broom found in 1980 by Randy Dykstra of Fulton, Illinois on U.S. Route 64 West, Lanark, Illinois, USA. In Chub Harper's field notes, he describes the broom as, "medium size, low." The original broom is famous for consistently producing excellent dwarf and miniature seedlings, notably L. decidua 'Gossard Dwarf' and 'Pretty Carole.'
