Pinus parviflora var. pentaphylla ‘Azuma’ is a slow-growing, pyramidal dwarf selection of Japanese White pine with silver-blue incurved needles held forward around the buds on the shoot ends. Typical rate of growth in most areas in 1.5 to 2.5 inches (4 – 6 cm) a year, resulting in an irregular dwarf pine 24 inches tall by 16 inches wide (60 x 40 cm) after 10 years in the landscape.
Although the precise history of this cultivar is unknown, it is known to be recorded in Japan as early as 1976. It is derived from a local provenance from Fukushima and Yamagata prefectures in Japan. A synonym commonly seen in the nursery trade is ‘Azuma-goyo.’ The use of the word “goyo” in Japanese white pine cultivar names is considered to be redundant because it is simply a translation for 5-needled pine.

A dwarf form of Japanese White Pine. Plant has some of the bluish needles we have seen. Plant is a real dwarf just growing about 1 to 3 inches a year. Very nice plant for Bonsai work. Great for troughs too!
