Larix laricina 'Nash Pendula' is a open, sparsely branched selection of tamarack with a strong upright leader and gently pendulous lateral branching holding bright green foliage. After 10 years, a mature specimen will measure 10 feet (3 m) tall and 4 feet (1.3 m) wide, an annual growth rate of 12 inches (30 cm) or more.
Despite being fairly well known in large arboreta and the nursery trade, this cultivar is of unknown origin. Given the latinized portion of the name, it could very well be an illegitimate cultivar name if found to be named after 1959.
