Pinus parviflora 'Azuma'

(Azuma-goyo Japanese White pine)

*Click on your approximate section of the country to see a detailed map.

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.

Stanley & Sons Nursery catalog

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!

    The World Checklist of Conifers:
    Lists the proper cultivar name for this plant as ‘Azuma-goyo’. It was introduced from Japan about 1976. It is a slow growing dwarf. Leaves silver blue, held forward around the buds on the shoot ends. ‘Azuma-goyo is from the provenance of Fukushima and Yamagata Prefectures.

    Azuma translates to Eastern Japan and Fukushima and Yamagata Prefectures would be in Eastrn Japan. Goyo translates to five leaves/needle see below.

    goyōmatsu (五葉松 Pinus parviflora, Pinus pentaphylla, Japanese white pine): its prefix goyō (五葉) is based on the observation this pine’s needles (modified leaves) are in a grouping or fascicle composed of five (go,五) needles (leaf 葉) which are shorter, denser and blue/grey in color than other pines.
