About
Juniperus chinensis, the Chinese juniper, is a species of plant in the cypress family Cupressaceae, native to China, Myanmar, Japan, Korea and the Russian Far East. Growing 1–20 metres (3+1⁄2–65+1⁄2 feet) tall, it is a very variable coniferous evergreen tree or shrub.
A variety of Juniperus chinensis referred to as "Shimpaku" is one of the top species used in the Japanese art of bonsai. Among the multiple cultivars of Shimpaku found in Japan, the most desirable due to its tight, fine foliage and excellent growing habits, is the "Itoigawa" variety.
How to grow it
This popular ornamental tree or shrub for gardens, parks, and in tough coastal conditions of hot sun and sandy fast-draining soils, has more than 100 named cultivars selected for various characteristics, such as yellow foliage (e.g. cvs. 'Aurea', 'Tremonia'), permanently juvenile foliage (e.g. cv. 'Shoosmith'), columnar crown shape (cv. 'Columnaris'), abundant cones, spiral branch pattern (e.g. cv. 'Kaizuka'), etc. First popular in the United States in the Los Angeles gardens in Mediterranean style homes, and now commonly found along both the West and East Coast in beach and coastal areas.
The Chinese juniper is widely used in bonsai, both as individual plants, such as the 250-year-old "Omiya tree" in the Birmingham Botanical Gardens in the UK, and in groups, such as the well-known Goshin on display at the National Bonsai and Penjing Museum at the US National Arboretum. The cultivar 'Shimpaku' is a very important bonsai subject.
