Pinus strobus 'Shaggy Dog' is a dwarf, spreading, selection of eastern white pine. Branching is uniform and layered; and foliage is medium green in color and shorter than many consider to be typical of the species. With age, plants will develop some apical dominance and will become broadly pyramidal. After 10 years of growth, a mature specimen will measure 4 feet (1.3 m) tall and wide, an annual growth rate of 3 to 5 inches (7.5 - 12.5 cm).
This cultivar originated as a witch's broom seedling selected in the late 1980s by Dr. Sidney Waxman of Storrs, Connecticut, USA.
