Petiole is short. Flowers are solitary or clustered at the top of branchlets or axillary, with hairy bracts and shallow wavy edges; Calyx limb lobes slender, conical, hairy; Corolla is red or white, 6- 12 mm long, with spreading lobes and 3-lobed tips; Stamens protrude outside the throat of the crown canal; Style long and prominent, stigma 2, straight, slightly apart. Flowering period may-July. Growing environment: I like sunshine in the snow, and I am more resistant to shade. I should avoid strong winds and scorching sun. Fine white flowers bloom in June, the tree is the smallest, and the branches and leaves are sparse, which is very pleasant and can be used as a basin to play with. Love the shade and fear the sun, and there are many trees in the mountains. Sowing in spring, or cutting in Huang Meiyu, should be watered with light tea. The temperature requirement is not strict, it is evergreen in South China and semi-evergreen in Southwest China. Strong drought tolerance, loose requirements for soil. Potted soil should be moistened with humic acid, which is loose and fertile, with strong permeability and good growth. Distribution: Jiangsu, Anhui, Jiangxi, Zhejiang, Fujian, Guangdong, Hong Kong, Guangxi, Sichuan and Yunnan. Born in mixed forests beside rivers or hills. Distributed in Japan and Vietnam. Sometimes training. The main value of the six trees in the snow is beautiful, lush, exquisite and elegant. It is a beautiful ornamental flower and leaf tree species in landscaping and an excellent bonsai material. It is one of the five famous trees in Lingnan bonsai, known as one of the "eighteen bachelors" in stump bonsai, and one of the bonsai plants exported to the United States by China after its entry into WTO. Propagation and cultivation. The management of ground planting in snow is simple and extensive. In the south, it can be planted in patches in the garden to form bushes. Summer looks as white as snow, giving people a cool and elegant feeling. Usually used to shape potted plants or make stump bonsai. First, the plants are integrated into a single stem type, and then the side branches are trimmed and bound according to the modeling idea to make various bonsai, which can achieve the ideal effect. Maintenance should be done outdoors in summer. If you put it indoors, it must be bright and ventilated, otherwise the branches will grow white, the leaves will turn yellow, and the lower leaves will often fall off in large numbers. Every year, the soil should be kept wet and dry properly, and the soil should be kept moist frequently in hot summer and dry season, and water should be sprayed on the leaves to keep the branches and leaves fresh. Liquid fertilizer can be applied three or four times during the growing season. If you don't continue to look at it in winter, you can let it fall leaves and then move into the cellar or bury it in the ground for the winter. If you overwinter in a low-temperature greenhouse, you can stay evergreen, the room temperature is not lower than 6℃, and you can keep good ventilation and sufficient light. Before leaving the house in early spring, the potted plants should be cut short and cored to keep their posture symmetrical and plump, and the bonsai should be trimmed and artistically treated. Like semi-shade, afraid of hot sun, strong germination, pruning resistance, easy planting and extensive management. Artificial cultivation in sandy loam with fertile soil. 65438+ 10 entered the greenhouse in mid-October, kept the room temperature at 10- 15℃, put it once a week, and then took it out of the greenhouse in late April and kept it in a cool place. Don't use big fertilizer, apply dilute liquid fertilizer once a month to keep the basin soil moist and grow well. If you keep it above 5℃ in the snow in winter, the branches and leaves will be green and evergreen, but the soil should not be too dry, so it should be slightly moist. Due to the strong ability of germination in snow, many new branches will sprout from the trunk and roots, so it is necessary to peel off redundant new technologies in time to avoid consuming nutrients and disturbing the normal development of trees. Prune the branches of the crown after flowering, otherwise it will affect the appreciation. Cutting propagation, dormant branch cutting, and semi-mature branch cutting from February to March. Cuttings 6-8 cm long are planted in slightly acidic fine sand loam for shading. Pay attention to watering after cutting, keep the seedbed moist, and the cuttings are easy to survive. Several cuttings can also be combined in 10~ 1 1 month for pot transplantation, and the seedlings of combined cuttings can be divided into single plant transplantation. Softwood cuttings can also be carried out in summer and early autumn. Generally, hard branches are used in early spring, and both hard branches and old branches can be used in rainy season, and scaffolding is needed to shade the sun. Pay attention to watering after transplanting, keep the seedbed moist and easy to survive. When making small or miniature bonsai, in order to make it take shape as soon as possible, perennial branches with beautiful posture and large tree shape are often taken in the rainy season from June to July, cut into horseshoes under the incision, inserted into warp stone or sand, covered with plastic film for heat preservation and sprayed with water, and can take root in about 40 days. At this time, it can be transplanted and molded with a little binding and trimming. Because this kind of grass is easy to find all over Shan Ye, some flower growers often dig it out of the forest and put it in flowerpots. Scattering and inserting method uses green open space to loosen soil, refine soil and level it. Spread the trimmed branches in one or two sections (about three centimeters) evenly on the ground that has been trimmed in advance, step on the topsoil or press it with something, and then water it. Then spray water every other day and start to take root and sprout ten days later. After 25 days, the first dilute liquid fertilizer was applied. After 50 days, apply 1: 1000 times urea to raise seedlings. It can be transplanted and planted in two months. Potting can be carried out in four months, and initial transplanting can be carried out at the same time. A year later, an ideal stump bonsai can be formed. Used as a hedge, it only takes half a year to form. Generally, ramet propagation is carried out in March of spring. Transplantation can be carried out all year round, with February to March in spring as the best.
