Typha cattails are perennial swamp herbaceous plants with plant heights of 1.4 to 2 meters, and some are as high as 3 meters or more. The rhizome is white, long and horizontal, with many fibrous roots growing at the nodes, and the old roots are yellowish brown. The stem is cylindrical, upright, hard and medium-solid. The leaves are flat and ribbon-shaped, more than 1 meter long, 2-3 cm wide, smooth and hairless. The base is in the form of a long sheath holding the stem. Flowers are unisexual, with spadix-like terminal cylindrical inflorescences shaped like candles. The male inflorescence is born in the upper part, 10-30 cm long, and the female inflorescence is born in the lower part, which is equal to or slightly longer than the male inflorescence. There is no gap between the two and they are closely connected. Grayish brown. The flowers are small, perianthless, and hairy. The male flowers have 3 stamens, the pollen is yellow, and each 4 stamens are clustered into blocks. The female flowers have no bracts, the ovary is linear, stalked, and the style is single. The fruit sequence is cylindrical, brown, and the nuts are small and have many white hairs. Contains small seeds, oval shape. The flowering period is from June to July, and the fruiting period is from July to August.

The green leaves of cattails are often used to decorate garden pools and lakesides to create waterscapes. Suitable as background material for flower borders and waterscapes. Potted plants can also be used to decorate the courtyard. Cattails are often used as cut flower material. The whole plant is a good raw material for papermaking. The leaves are called cattail and can be used for weaving, and the pollen can be used as medicine and is called cattail. Cattail sticks dipped in oil or not are used for lighting. The hairs on the female inflorescences are called cattail velvet and can often be used as pillows. The young shoots are called cattail, which is delicious and edible. It is a famous aquatic vegetable.

The place where cattails are planted should have sufficient sunlight, ventilation and light transmission. The management is more extensive, please refer to the management of Iris. It can be sown and cultured by divisions, usually by divisions. For ramification, the old plants can be dug up in early spring and cut into several clusters with a sharp knife. Each cluster has several small buds as breeding materials. Plant in pots or in the open. Generally, it needs to be replanted every 3 to 5 years to prevent the root system from aging and the trees to not flourish.

Typha are propagated by division and mowing. Before germination in spring, take out the underground rhizome and cut it into a section of about 10cm with 2-3 buds. After planting the rhizome in the soil, when the stem buds grow horizontally in the soil to more than 30cm, the top buds will bend and grow upward to produce new leaves. , roots grow downward to form new plants. As the underground rhizomes of each plant extend to all sides, new plants continue to grow, gradually forming a group. After three consecutive years of growth, the root system becomes intertwined, the soil fertility decreases, and the plant growth declines, so it must be replanted. When potting, it is advisable to use soft and fertile soil, with a 5-10cm layer of clear water above it. Add new water in time in summer, and spray water on the leaves frequently to keep them clean. After the frost, cut off the dead matter on the ground and place it in a cold room to overwinter. This species has loose environmental requirements, strong adaptability, and certain cold tolerance. It is a light-loving plant, not shade-tolerant, and requires soft and fertile soil. It is suitable to grow in shallow lakes, ponds, ditches and other environments. After planting, pay attention to shallow water maintenance to avoid excessive flooding and water loss and drought. Weeds should be removed frequently and timely top dressing should be carried out. After 4-5 years, because the underground rhizomes grow quickly, the rhizomes are crowded, and the above-ground plants are also dense, they need to be pruned and planted again. In the second year after planting, flowering will increase and yield will increase, and harvest can begin. During the flowering period from June to July, when the pollen of the male flowers matures, choose a sunny day, pinch the male flowers with your hands, dry them in the sun and crush them, and use a fine sieve to remove impurities. Cattails have thick underground rhizomes, and the above-ground stems are upright and cylindrical, without branches. Its leaves are as slender as swords, and its color is bright and elegant. Some literati often planted it in water basins and displayed it in the courtyard, which gave it a unique taste.

Take the mother cattail plant out of the pot in early spring every year, wash away the soil, and cut the underground rhizome into 10 cm long segments. Each segment should have 2-3 lateral buds, and then Plant flat in pot soil. After entering the water, the lateral buds on the rhizome sprout first, and new rhizomes are first drawn out in the underwater soil. When the new rhizomes grow to about 30 cm, the top buds on the top begin to sprout and bend upward to stick out of the soil surface, and then they are drawn out. new leaves, thus growing into new plants. The underground rhizomes continue to expand and spread as the plant grows, and will cover the entire pot after 2 years. At this time, the old rhizomes gradually wither, and the new rhizomes have nowhere to extend, and the growth potential also declines, so they should be replanted every 2 years. . Cattails have strong cold tolerance and can be stored in pots on the balcony or on the south side of an outdoor house in winter. It does not matter if the pot freezes. It likes plenty of sunlight, so it should be displayed outdoors all year round.
