About

Ilex crenata, also known as Japanese holly or box-leaved holly, is a species of flowering plant in the family Aquifoliaceae, native to East and Southeast Asia.

How to grow it

Ilex crenata is grown as an ornamental plant for its dense evergreen foliage, and is a popular plant among bonsai enthusiasts and suburban property developers alike. It is superficially similar in appearance to boxwood (box), and is often used in similar situations, such as low hedging; but it can readily be distinguished from boxwood by its alternate, not opposite, leaf arrangement.

Numerous cultivars have been selected, including plants with the leaves variegated (e.g. 'Golden Gem', 'Shiro-Fukurin'), dark green (e.g. 'Green Lustre'), or greyish-green (e.g. 'Bad Zwischenahn'); with yellow fruit (e.g. 'Ivory Hall'); and with an erect habit (e.g. 'Chesapeake' and 'Sky Pencil'), and spreading (e.g. 'Green Island', 'Hetzii'), or dwarf (e.g. 'Mariesii', 'Stokes'). The cultivars 'Golden Gem' and ‘Fastigiata’ (Fastigiata Group) have gained the Royal Horticultural Society's Award of Garden Merit.

Where it grows

I. crenata is native to temperate and subtropical parts of eastern China (including Hainan), Japan, Korea, Taiwan, the Himalayas (Nepal, India, Tibet), Myanmar, Vietnam and Sakhalin, Russia.
