Pinus strobus 'Horsham' / Horsham white pine

Pinus strobus 'Horsham' is a flattened globose, dwarf selection of Eastern white pine that with age, assumes more of a broadly conical form. Branching is fairly open and needles are more-or-less species typical and dark, Blue-green in color. This conifer is known for producing copious seed cones from a young age and is the seed parent of many other well-known dwarf white pines. After 10 years of growth, a mature specimen will measure 24 to 30 inches (60 - 75 cm), an annual growth rate of 2 to 4 inches (5 - 10 cm).

This cultivar is of unknown origin. One of its first mentions is in Layne Ziegenfuss's Hillside nursery 1970 catalog, where he listed it as 'Horsham Broom.'
