Ilex crenata, also known as Japanese Holly or Box-Leaved Holly, is an attractive evergreen shrub or small tree native to eastern China, Japan, Korea, Taiwan, and Sakhalin. It can grow up to 10-15 ft tall and has a trunk diameter of up to 7.5 inches. The glossy dark green leaves are small, measuring 10-30 mm in length and 10-17 mm broad, with a crenate (wavy) margin, sometimes spiny. The plants are dioecious, meaning they have separate male and female plants, and produce white, four-lobed flowers. The fruit is a black drupe, about 5 mm in diameter, containing four seeds.
Ilex crenata is highly versatile and can be used in various landscaping applications. It is frequently grown as a hedge in North America and Japan due to its excellent ability to tolerate trimming. Its compact, dense foliage adds texture and elegance to any garden, making it a popular choice among gardeners. The plant is also an excellent option for topiary, with its small leaves and responsiveness to shaping.
Ilex crenata is well-suited to acidic soil, with a pH range of 3.7 to 6.0. This adaptable species thrives in different climates and is capable of withstanding temperature fluctuations. Not only does it provide year-round greenery, but it also attracts birds with its fruit.
Whether you need a versatile hedge, an ornamental focal point, or a plant for topiary, Ilex crenata is an excellent choice. Its classic beauty and adaptability make it a go-to option for both professional landscapers and gardening enthusiasts.
