Pinus banksiana'Nana' is a slow-growing, dwarf selection of Jack pine with short light green needles and a low, spreading growth habit. After 10 years of growth, a mature specimen will be only 16 inches tall (40 cm) and 24 inches (60 cm) wide, a rate of growth slightly exceeding 1 inch (2.5 cm) per year.
The origin of this cultivar is unknown. It is thought to have originated at the Watnong Nursery in New Jersey in the early 1970s. However a latinized name such as this suggests that it may have been selected and named prior to 1959.
