Pinus banksiana 'H.J. Welch' / H.J. Welch Jack pine
Pinus banksiana'H.J. Welch' is a compact, globose, bushy dwarf selection of Jack pine with shiny, short, medium- to light-green needles. Typical rate of growth in most areas in 1 to 2 inches (2.5 - 5 cm) per year, uniformly in all directions. After 10 years, a mature specimen will grow to dimensions of 18 inches (45 cm) tall and wide.
This cultivar originated as a seedling selected in 1974 by A.G. Johnson at Minnesota Botanical Gardens, Minneapolis and sent to Humphrey Welch in Great Britain where it was named and introduced to the nursery trade.
