It is a lily plant, also known as a seven leaf one branch flower and Grass River car. It is a perennial herb with a height of about 50cm. The rhizome at the bottom is brownish brown, growing horizontally and relatively thick, with a very rough surface. The stem is relatively simple, standing up, smooth and hairless. Petiole is about 1-3 cm long, leaves are papery or membranous. In summer, it will produce yellow and green flowers. The pedicel will be drawn out from the stem without branches.
It is very difficult to plant in the north. Generally, it lives in Yunnan and other southern areas. It likes to grow in a wet place, so it is not very suitable in the north. If planting is needed in the south, the seeds will mature and be picked in November of the previous year. You can choose river sand or other particles to rub and wash the red seed coat outside it, and then wash it under the clear water. Cover the outside with wet sand so that the seeds can sprout. In the spring of the next year, the seeds can be evenly sown into the soil when they are exposed.
