Pinus banksiana 'Neponset' / Neponset Jack pine

Pinus banksiana 'Neponset' is a flat-topped, spreading cultivar of Jack pine with short, light-green foliage. In the garden, the expected 10-year growth at maturity can be expected to reach 1.5 feet (45 cm) tall and 3 feet (1 m) wide, suggesting an annual rate of growth 1 to 2 inches (2.5 - 5 cm).

This cultivar originated as one of four seedlings selected in 1979 by Humphey Welch and Al Fordham at the Arnold Arboretum, Boston, Massachusetts. All of which were named for native American tribes, 'Chippewa,' 'Manomet,' and 'Wisconsin' being the other three.
