Pinus koraiensis 'Winton' is a robust, broadly upright, tree form of Korean pine with dense, uniform branching, and long blue-green needles with their signature "kink" in their upper third. After 10 years of growth, a mature specimen will measure 10 feet (3 m) tall and wide, an annual growth rate of 1 foot (30 cm) or more.
[Dax Herbst] Evidently there is some discrepancy concerning the habit of this cultivar. Unlike the description noted on Stanley and Sons website, I was given first hand information that this cultivar is not narrow and upright growing but rather will become a wide-growing specimen. The first hand information was passed along from Larry Stanley to a friend who forwarded it to me. Until more is known, that's all I have to go by.
This cultivar originated as a seedling selected in 1964 by H. G. Hillier of Hillier & Sons Nursery, Winchester, United Kingdom.
