Pinus strobiformis 'Undulata' / undulating southwestern white pine

Pinus strobiformis 'Undulata' is a moderately fast growing, irregular upright selection of southwestern white pine with loose, semi-pendant, undulating branches; and thick, bright blue needles that grow with a slight twist. After 10 years of growth, a mature specimen will measure 4.5 feet (1.5 m) tall and wide, an annual growth rate of around 6 inches (15 cm).

This cultivar is a rather obscure and can be rather difficult to locate. It is of unknown origin.
