Pinus densiflora 'Umbraculifera Nana' is a dwarf, v-shaped, flat-topped selection of Japanese Red pine, growing broader than wide with a similar structure to it's parent tree, P. densiflora 'Umbraculifera,' but somewhat slower growing. After 10 years of growth, a mature specimen will measure 32 inches (80 cm) tall and 36 inches (100 cm) wide, and annual growth rate of 3 to 4 inches (7.5 - 10 cm). Be aware that these numbers are meaningless if Japanese pruning and styling techniques are used as part of a routine maintenance program.
This cultivar was introduced to the nursery trade in the early 1990s by Le Feber Nurseries, Boskoop, The Netherlands. It is not certain whether the plant originated as a seedling or a slower growing mutation. The plant is seen in the trade under many various names which include, 'Umbraculifera Compacta' and 'Tanyosho Compacta.'
