Ilex cornuta, also known as bird's nest, tiger thorn and cat thorn, is also called "Christmas holly" and "Christmas tree" because it is often used for Christmas decoration and beautification in European and American countries. Its leaves are peculiar in shape, dark green and bright in color, and evergreen all the year round. In autumn and winter, the red fruit is round and bright, which is an excellent tree species with considerable leaves and fruits. Potted plants with different specifications can be made and decorated in halls, bedrooms, porches and other places, with dignified atmosphere and good decorative effect. Because of its strong root system and dense branches and leaves, it is also a good tree species for making bonsai. Ilex cornuta is cold-resistant, and it also has a good performance when planted in a small courtyard or as a landscaping plant. In addition, the branches of Ilex cornuta are also common materials for flower arrangement. In recent years, some people have processed the spineless holly into a tower shape, and its bright red fruit contrasts with the green leaves, which is called "full house" by merchants and is very attractive.
