Pinus resinosa 'Quinobequin' / Quinobequin red pine

Pinus resinosa 'Quinobequin' is a slow-growing, mounding, globose, selection of red pine with species-typical, long dark olive-green needles that create a ring of shorter needles as a second flush in late summer; and conspicuous red branches. After 10 years of growth, a mature specimen will measure 40 inches (1 m) tall and 4.5 feet (1.5 m) wide, an annual growth rate of 4 to 6 inches (10 - 15 cm).

This cultivar originated as a witch's broom seedling selected in the 1970s by Al Fordham, former head propagator at Arnold Arboretum, Jamaica Plain, Massachusetts. Quinobequin is the Native American name for Massachusetts' Charles River.
