I think kids who live in rural areas or grew up in rural areas should know what kind of plants water plants are. As the name suggests, generally water plants are grasses that grow inside water. There are many types of water plants, water plants are generally divided into the foreground grass, back view grass, in the landscape grass, clumps of water plants, crown water plants, pepper grass water plants, water ficus water plants, Moss class water plants and so on. In rural ponds water plants can be found everywhere, and generally grow very dense.

We will often see all kinds of water plants, but generally do not get too close to the side of the water plants, because generally snakes and other animals prefer to stay in such an environment. For the sake of their own safety, or do not approach. Some farmers will cut these grasses to feed the sheep, which is a good choice, but must pay attention to safety.

Below, and a look at the types and characteristics of watercress.

Bitter grass:

Commonly known as noodle grass, dragon grass, flat grass, is an aquatic herb. With stolons, leaf basal, leaf blade narrow as a band, leaf length with the water depth and there is a difference, leaf blade turquoise translucent, ting ting standing in the water. Strong adaptability to water quality, like weak alkaline water, do not like high temperature, cold, like light.

Curly Leaf Lobelia:

Leaf shape is also like a band, but the rotating upward growth, from the top of the base, very neatly like a wave-shaped upright in the water, very chic and beautiful. Require more light, also do not like high temperature, suitable for temperature 24 ℃.

Crown Grass:

The petiole is stout, the leaf blade is wide and long and more, the plant height is more than 60 centimeters, it is a gorgeous large water plants. Native to Brazil, similar to terrestrial Brazilian wood, suitable for planting in large aquariums. Suitable for growth in weakly acidic, neutral water, temperature-loving, light-loving, water temperature should be more than 24 ℃, 26?28 ℃ is most suitable.

Crown of Fine Leaves:

It is a small marsh plant, native to Brazil. The lanceolate leaves are 10-15 centimeters long and 1 centimeter wide, barely petiolate, and about 20 centimeters tall throughout, with 2-3 spiraled flowers about 1.5 centimeters large with six pistils. The leaves are green and firm, with well-defined main leaf veins and less distinct veins on the sides. Propagation is by division of buds, with daughter plants growing on the propagating stems of the parent plant. It likes strong light. 20-25 ℃ is optimal.

Argentina crown grass: native to Brazil, Guyana, Argentina. Leaf blade is oval, 15-25 cm long, 10-15 cm wide, can produce 4 cm size flowers, about 24 stamens, fruit 0.3 cm large. Requires more sunlight. Water temperature of 22-28 ℃ is appropriate.

Mini Crown:

Native to Brazil. Lanceolate leaf shape 5-15 cm long and 0.5-1 cm wide adapts to different light conditions. The small size makes it a water plant that can be freely arranged in the aquarium. It is even better as a foreground plant. Cannot be planted in coarse sand. It needs to be supplemented with iron fertilizer at any time. Reproduces by stolons. Water temperature is 22-27℃.

Pocket Crown:

A small aquatic amphibious plant from Brazil, Uruguay and Argentina. Lanceolate leaves 3-5 cm long and 0.5-1 cm wide. Petiole 2-3 cm, roots often red, flowers 1.5 cm, with 9 pistils, fruit 0.13 cm. Leaf stems in water are short about 7-12 cm long and 0.5-0.8 cm wide. Light conditions are 50W/100L of water. Supplemental iron fertilizer is required. Utilize daughter plants to propagate by branching. Water temperature 18-28 ℃ is appropriate.

Wave Crown:

Native to southern Brazil. Grows in waters with slow currents and low water temperatures. Leaves in the water are lanceolate, 25-35 centimeters long and 2-3 centimeters wide, with a wavy edge so called wave grass. There are oval aerial leaves, 15 cm long and 9 cm wide, and flowers about 2 cm. Reproduction is done by using the lateral buds that grow on the rhizome. Water temperature of 22-30 ℃ is preferred.

Flower Crown:

Native to southern North America, West India. It is one of the more common varieties. The leaves do not survive long. Juvenile leaves are narrow, pointed and have no petiole. The mature leaves are heart-shaped 20-30 centimeters long and 3-4 centimeters wide with yellow veins. These underwater leaves disappear when the floating wild grows. It does not tolerate a lot of light, less than 12 hours a day. Regular pruning of the leaves is required to maintain the growth of its underwater leaves. Propagation by side shoots. Suitable for weakly acidic water, 20-26 ℃ water temperature.

Longleaf Crown:

Produced in Central America and southern Brazil. It is a very long, large ornamental water plant. Lanceolate or elliptic leaves, 15-25 centimeters long and 3-10 centimeters wide, very pointed at both ends. The flowers are about 1.5 cm in size and the fruit 0.2 cm. Requires soft water and coarse sandy soil, and needs to be grown in large, tall aquariums or bog aquariums. Water temperatures of 22-28°C are preferred.

Crown of Big Leaves:

Native to Guyana, western Brazil to Argentina. Arrow-shaped or heart-shaped, oval leaves, 20-30 cm long. Petiole with spines, flowers 3 cm large. Needs a wide aquarium, strong light, fertile substrate and weakly acidic water. Reproduces by using buds on the pedicel. Reproduction is difficult. Suitable for weakly acidic water, 20-27 ° C water temperature.

Little Seafan:

Native to the northern part of South America, the Amazon River basin. Has heart-shaped leaves ranging from dark green to teal brown with pointed tips, supported horizontally by petioles. The leaf blade can be up to 15-20 centimeters long and 5-10 centimeters wide, with 5-7 main leaf veins. Once acclimatized, it can grow extremely well in bright light conditions. Its flowers can be seen on the surface of the water. Propagation is by molecular plants as in the case of Crown Grass. Water temperature 22-28 ℃ is preferred.

Red Egg:

A highly adaptable water plant, native to southern Brazil. Height up to 40-50 centimeters. For mature leaves slightly reddish, 30-40 centimeters long, 4-5 centimeters wide, with obvious veins and wrinkled edges. The ornamental effect in strong light is excellent, but strong light needs to strengthen the supply of fertilizer. Cannot flower in water. It can be reproduced by using the daughter plants divided from the petiole or the new shoots from the root. Water temperature of 22-28 ℃ is preferred.

Elephant's ear:

A water plant from south-central North America and Mexico. It is very adaptable and is suitable for growing alone in large aquariums. Obtuse head heart-shaped leaf shape, 20-25 cm long and 10-15 cm wide. Has long-stalked floating leaf growth, but can be maintained in the water by simply subtracting it. Can produce white flowers in the water and can bear fruit after artificial pollination. Reproduces by lateral shoots from the stem. Water temperature of 22-28 ℃ is preferred.

Tiger:

Native to North America, also known as the water guacamole. Leaf blade oval, leaf length 30 mm, strong light exposure, the top of the stem on the leaf blade was red to tea color change. Prefer stronger light and lower water temperature. Aquarium water temperature of 16 ~ 24 ℃.

Water plantain:

Also known as water cabbage, the leaves are submerged, basal, light green, thin and transparent. Flowers bloom on the surface of the water, growing in ponds, small lakes and slow-flowing ditches, east China and Guangdong, Guangxi are distributed.

Understanding so many types of water plants and characteristics, now is not some impression. These water plants are generally more adaptable, like weak alkaline water, cold hardy, toward the light. Generally suitable for them to grow at a temperature of about 20 degrees Celsius. Some water plants need higher temperature growing environment, the highest can reach more than 28 degrees Celsius. And water plants are widely distributed.
