Pinus mugo 'Winter Sun' is an dwarf, upright, globose selection of mugo pine with uniform branching and species-typical foliage than turns bright gold in late fall into winter with the onset of colder temperatures. After 10 years of growth, a mature specimen will measure 28 inches (70 cm) tall and 60 inches (1.5 m) wide, an annual growth rate of 2 to 3 inches (5 - 7.5 cm), more outward than up.
This cultivar originated as a seedling selected in the late 1980s by Yamina Rare Plant Nursery, Monbulk, Victoria, Australia. In Europe, this conifer is often marketed on the German commercial name, Wintersonne„¢.
