What kind of plant is this? I don't know how to raise it if I buy it

alias Zi Kui, Palmae, Herba Solani.

evergreen shrub with slightly larger stem base. The leaf blade is pinnately divided, expanding outward into an arch, the small pinnae is lanceolate, the apex is soft, the long tail is tapered and is short and 2-lobed with unequal length; Leaf axis is smooth and yellow-green, and the upper part is covered with white powder at first. Spikelets are born under leaf sheaths, with many branches and arranged in conical bouquets. The flowers are monoecious, small and golden yellow, with 3 petals and 3 sepals, and 6 stamens. Ovary 3-loculed with short style and broad stigma. The fruit is gyro-shaped, purple-black and without endocarp.

It is native to Madagascar, and cultivated in Guangdong and Guangxi, China. It is mostly planted among flowers in the courtyard.

reproduction: the family can reproduce by dividing plants in spring, summer and autumn. Garden soil can be mixed with some sand as basin soil.

cultivation: it likes warmth and has good shade tolerance, but it can grow better if it is placed in a bright place indoors. Cold tolerance is not strong, and the temperature should be kept above 8 degrees Celsius in winter. Keep the soil moist at ordinary times, water the topsoil when it is dry, and water it in winter when the basin soil is 2/3 dry. It is easy to spray water on the leaves during dry weather. Apply compound fertilizer mainly nitrogen fertilizer once a month in spring, summer and autumn. In addition, when potted indoors, it is necessary to rotate the flowerpot regularly, because the plants have phototropism, so that the plants grow evenly and beautifully around.

The new buds sprouting from the lower part of Herba Solani can be propagated by dividing plants, and the yellow leaves and old leaves that affect the appearance of the plant can be removed when pruning, and proper pruning can also ensure good lighting of the whole plant.

The leaf tip and leaf margin of Solanum lyratum L. appear dry scorch during growth, the main reasons are as follows: ① The air is too dry. Sunflower likes high air humidity, and when the air is too dry, it will cause the focal tip and edge of the leaves. Water should be sprayed on the leaves and the surrounding environment 3~4 times a day during the whole growth period to improve the air humidity. But stop watering after dormancy. ② The sunshine is too strong. Sunflower likes semi-cloudy environment from May to September. When the sun shines directly, the leaves will turn yellow, and there will be phenomena such as scorched tips and scorched edges. During this period, it should be placed under a shade shed or a big tree to avoid direct sunlight. ③ The basin soil is too dry. During the growth period, the nightshade needs to be supplied with sufficient water. When the basin soil is dry for a long time, because the growth of plants can not get enough water, the tip and edge of leaves will dry and scorch. ④ The basin soil is too wet. It is not that as long as there is water in the basin soil, plants can absorb and utilize it. When the pot soil is too wet, it affects the respiration of the roots of plants, thus affecting the absorption of water by the roots, and leading to the lack of water in plants and the emergence of focal tips and edges of leaves. ⑤ Excessive fertilization. Excessive fertilization will cause the reverse osmosis phenomenon of plant root cells and make plants lose water. When the degree is light, it will lead to the focal tip and edge of leaves, and when it is serious, it will cause root rot and death.
