Pinus strobus 'Explosion' / Eastern White Pine

Pinus strobus 'Explosion' is a tidy dwarf form of Eastern white pine. Branching is fairly uniform resulting is a symmetrical globose plant. Needles are a bright light green, perhaps only somewhat smaller than those typically seen in the species. Rate of growth for most areas is 1 to 2 inches (2.5 - 5 cm) a year resulting in a 15 inch (38 cm) tall and slightly wider specimen in the landscape of 10 years of growth.

Rich Eyre of Woodstock, Illinois is credited with the origin and introduction of the cultivar. He discovered the witch's broom on an Eastern White pine in southern Milwaukee, Wisconsin that was to become 'Explosion' sometime in the late 1990s.
