< h2 class="title-text" > morphological features</h2>
Boxwood is a shrub or small tree, 1–6 m tall; the branches are cylindrical, longitudinally ridged, off-white; the twigs are four-sided, fully covered with short soft hairs or hairless on both sides, with internodes 0.5–2 cm long. Leaf leathery, broad oval, broad inverted ovate, ovate oval or oblong, most 1.5–3.5 cm long, 0.8–2 cm wide, rounded or blunt at the apex, often with small notches, not sharp, rounded or sharply pointed or wedge-shaped at the base, bright leaf surface, raised midrib, often with fine hairs in the lower half, pronounced lateral veins, flat or slightly protruding midrib of the leaf, often densely covered with white short-line stalactites on the midrib, no lateral veins, petiole 1–2 mm long, and hairy on it.
The inflorescence is axillary, cephalic, densely flowered, inflorescence shaft 3–4 mm long, hairy, broadly ovate bracts. Length 2-2.5 mm, somewhat hairy on the back; male flowers: about 10 flowers, no peduncle, outer sepals ovate oval, inner sepals nearly round, 2.5-3 mm long, hairless, stamens with anthers 4 mm long, sterile pistils with rod-like stalks, the ends are expanded, about 2 mm high (about 2/3 of the sepal length or several equal lengths as the sepals); female flowers: sepals 3 mm long, the ovary is slightly longer than the flower post, hairless, the peduncle is thick, the stigma is inverted, and the lower extension reaches the middle of the peduncle.
The capsules are nearly spherical, 6–8 (-10) mm long and 2–3 mm long. The flowering period is in March and the fruiting period is from May to June.
<h2 class="title-text" > habitat</h2>
There are many valleys, streams, and forests, with an altitude of 1200-2600 meters. It is produced in Shaanxi, Gansu, Hubei, Sichuan, Guizhou, Guangxi, Guangdong, Jiangxi, Zhejiang, Anhui, Jiangsu and Shandong provinces and regions of China, and some of them belong to cultivation. The type specimen was collected from Changyang County, Hubei Province.
< h2 class="title-text" > growth habit</h2>
Boxwood prefers fertile and loose loam soils, slightly acidic soils or slightly alkaline soils can be adapted, and can also grow in calcareous soils. Potted plants can be mixed with an appropriate amount of bran ash from matured pastoral soil or saprophyll soil. It is shade tolerant and light-loving, and can maintain good growth under general indoor and outdoor conditions. In long-term shaded environments, although the leaves can remain emerald green, they can easily lead to long or weak branches. It likes humidity and can tolerate rainy weather for about a month, but avoid long-term accumulation of water. Drought-tolerant, as long as the surface soil or potted soil is not completely dry, there is no abnormal performance. Heat and cold resistance, can withstand summer exposure and cold resistance of about minus 20 degrees Celsius, but should be more ventilated and transparent in summer when high temperature and humidity. The soil requirements are not strict, preferably easy and fertile sandy loam soil, potted plants can also be used with vermiculite, peat or soil, and the alkali resistance is strong. It is extremely tillering, resistant to trimming and easy to form. After the autumn is fully illuminated and dormant, the leaves can turn red.

About boxwood is still a very interesting topic, Li Yu called it a gentleman's style, known as "the gentleman in the wood". In his "Casual Love And Occasional Mail", it is even recorded that "the boxwood is one inch per year, does not overflow a single inch, and shrinks by one inch in leap years, which is the destiny of heaven." In fact, this statement is also mentioned in some other books, such as Su Shi has a poetry cloud: "There are countless grasses and trees in the garden, only the yellow poplar is a leap year." "The Naturalist" even mentioned that someone had done a test, saying that the leap year boxwood was not reduced, but not long. There is also the following record of the harvesting of boxwood in the "Youyang Miscellaneous Tricks": "The world-heavy boxwood is also fireless. Test it with water, sink without fire. Whoever takes this wood will find no star in the obscure night, and if he cuts it down, he will not crack it. These statements have somewhat cloaked boxwood in a mysterious cloak, and added a lot of interest to boxwood works becoming people's beloved playthings.
Because of the slow growth, the wood of the boxwood is extremely delicate, the naked eye can not see the brown eye (pores), but still because the boxwood grows slowly, it is difficult to have large materials, mostly used with high-grade mahogany inlay or processed into extremely fine carvings, there are no large works, and because of this, boxwood carving works are often mistaken by beginners as ivory production. It can be said that boxwood is extremely difficult to make large pieces of furniture, and if it appears, it must be a treasure.
The aroma of boxwood is very light, very light, elegant and not vulgar, is the kind of taste that can be described by fragrance, and can repel mosquitoes, in addition, boxwood also has the effect of sterilization and anti-inflammatory and hemostasis, in the mountain people where boxwood grows, there are picked boxwood leaves for hemostasis and placed boxwood branches to repel mosquitoes and flies.
