Pinus banksiana'Wisconsin' is a dense, slow-growing bushy form of Jack pine with short, light-green needles. Although quite globose in its youth, this selection will grow wider than tall at maturity and beyond. After 10 years of growth a mature specimen will measure 16 inches (40 cm) tall and 20 inches (50 cm) wide, a growth rate of 1.5 to 2 inches (3 - 5 cm) per year.
This cultivar was one of four seedlings that were selected and named in 1974 by Al Fordham and Humphrey Welch at the Arnold Arboretum, Boston, Massachusetts. All of which were named for native American tribes, 'Chippewa,''Manomet' and 'Neponset' being the other three.
