Morphological characteristics of aquatic plants

Common species:

Vallisneria: commonly known as noodle grass, asparagus grass, and shoulder grass, it is an aquatic herbaceous plant. It has stolons, basal leaves, and the leaves are long and narrow like a belt. The length of the leaves varies with the depth of the water level. The leaves are green and translucent, and they stand like jade in the water. It has strong adaptability to water quality, likes weakly alkaline water quality, does not like high temperature, is cold-tolerant, and likes light.

Asparagus with curly leaves: The leaf shape is also like a belt, but it grows upwards in a rotating manner. From the top of the base, it stands upright in the water in a very neat and wavy shape, which is very unique and beautiful. It requires more light and does not like high temperatures. The suitable temperature is 24°C.

Crown grass: The petiole is thick, the leaves are wide and long, and the plant height is more than 60 cm. It is a gorgeous large aquatic plant. Native to Brazil, it is similar to the terrestrial Brazilian wood and is suitable for planting in large aquariums. It is suitable for growing in weakly acidic and neutral water. It likes temperature and light. The water temperature should be above 24°C, with 26-28°C being the most suitable.

Crownia tenuifolia: It is a small swamp plant native to Brazil. The lanceolate leaves are 10-15 cm long and 1 cm wide, with almost no petiole and a total height of about 20 cm. The 2-3 spiral flowers are about 1.5 cm in size and have six pistils. The leaves are green and strong, with clear main veins and less obvious veins on both sides. Propagation by budding will produce daughter plants on the reproductive stems of the mother plant. Like bright light. 20-25℃ is optimal.

Argentine crown grass: native to Brazil, Guyana, and Argentina. The leaves are oval, 15-25 cm long and 10-15 cm wide. They can produce flowers of 4 cm in size, with about 24 stamens, and the fruit is 0.3 cm in size. Requires more sunlight. The appropriate water temperature is 22-28℃.

Mini crown: native to Brazil. The lanceolate leaves are 5-15 cm long and 0.5-1 cm wide to adapt to different lighting conditions. Its small size makes it an aquatic plant that can be placed in any aquarium. It is also excellent as a foreground grass. Cannot be planted in coarse sand environment. Iron fertilizer needs to be supplemented at any time. Reproduces by stolons. The appropriate water temperature is 22-27℃.

Pocket crown: a small waterway amphibian produced in Brazil, Uruguay, and Argentina. The lanceolate leaves are 3-5 cm long and 0.5-1 cm wide. The petiole is 2-3 cm, the root is often red, the flower is 1.5 cm, has 9 pistils, and the fruit is 0.13 cm. The short leaf stems in water are about 7-12 cm long and 0.5-0.8 cm wide. The lighting conditions are 50W/100L water. Iron fertilizer needs to be supplemented. Propagate by budding from daughter plants. The appropriate water temperature is 18-28℃.

Wavy Crown: Native to southern Brazil. Grows in waters with slow currents and low water temperatures. The leaves in the water are lanceolate, 25-35 cm long and 2-3 cm wide. The edges are wavy, so it is called wavy grass. It has oval aerial leaves, 15 cm long and 9 cm wide, and the flowers are about 2 cm. Propagate using lateral buds growing from rhizomes. The appropriate water temperature is 22-30℃.

Flower Crown: Native to southern North America and West Indies. Belongs to the more common varieties. The leaves do not survive long. Juvenile leaves are narrow, pointed and without petioles. The mature leaves are heart-shaped, 20-30 cm long, 3-4 cm wide and have yellow veins. These underwater leaves will disappear when floatable plants grow. Intolerant of a lot of sunlight, less than 12 hours a day. To maintain the growth of its leaves in the water, the leaves need to be pruned regularly. Reproduction by lateral buds. Suitable for weakly acidic water, water temperature 20-26℃.

Crown longleaf: native to Central America and southern Brazil. It is a very long large ornamental aquatic plant. Lanceolate or elliptical leaves, 15-25 cm long, 3-10 cm wide, with pointed ends. The size of the flowers is about 1.5 cm, and the fruit is 0.2 cm. It needs soft water and coarse sandy soil environment, and needs a large, tall aquarium or swamp aquarium for planting. The appropriate water temperature is 22-28℃.

Bigleaf Crown: Native to Guyana, western Brazil to Argentina. Arrow-shaped or heart-shaped or oval leaves, 20-30 cm long. The petioles are spiny and the flowers are 3 cm in size. It requires a large aquarium, strong light exposure, fertile foundation stone and slightly acidic water quality. Propagate using buds on peduncles. Breeding is more difficult. Suitable for weakly acidic water, water temperature 20-27℃.

Little sea sail: native to northern South America and the Amazon River Basin. It has heart-shaped leaves ranging from dark green to dark brown. The leaf tips are pointed and supported horizontally by the petiole. The leaves can be 15-20 cm long, 5-10 cm wide, and have 5-7 main veins. As long as it adapts to the environment, it can grow very well under bright light conditions.

Its flowers can be seen on the surface of the water. Molecular strain propagation like crown grass. The appropriate water temperature is 22-28℃.

Red egg: a highly adaptable aquatic plant native to southern Brazil. The height can reach 40-50 cm. The mature leaves are slightly red, 30-40 cm long and 4-5 cm wide, with obvious veins and wrinkled edges. The viewing effect under strong light is excellent, but the supply of fertilizer needs to be strengthened under strong light. Flowers cannot bloom in water. Propagation can be achieved by using the daughter plants from the petioles or the new shoots from the roots. The appropriate water temperature is 22-28℃.

Elephant ear: an aquatic plant native to central and southern North America and Mexico. It is extremely adaptable and is more suitable for planting alone in large aquariums. The leaves are blunt-headed and heart-shaped, 20-25 cm long and 10-15 cm wide. Long-stalked floating leaves grow, but only need to be cut back to maintain growth of leaves in the water. It can bloom white flowers on the water surface and bear fruit after artificial pollination. Reproduces by stem lateral buds. The appropriate water temperature is 22-28℃.

Tiger ear: native to North America, also known as water melon seeds. The leaves are oval and 30 mm long. When exposed to strong light, the leaves on the top of the stem change from red to brown. It likes stronger light and lower water temperature. The suitable water temperature for the aquarium is 16~24℃.

Water plantain: also known as water cabbage, the leaves are submerged and basal. The leaves are light green, thin and transparent. The flowers bloom on the water and grow in ponds, small lakes and slow-flowing ditches. They are distributed in East my country, Guangdong and Guangxi.

Water fig: The rhizomes extend laterally and green leaves grow upward. It has an extremely wide adaptability to water quality and is durable and easy to grow. However, in soft water with a water temperature exceeding 30°C, the leaves shrink to small sizes and the growth is slow. The suitable temperature is 5~20℃. Mostly used for aquarium landscaping of alkaline fish.

Tuocao: It is Japanese, meaning grass by the water. Tuocao-as the name suggests, it is a tuft of grass, but its content is not that simple. Turmeric can generally be divided into three categories

1. Aquatic plants--all are made from land leaves transformed from water plants or directly from land leaves. Appreciate both the above-water leaves and the underwater leaves. Creatures such as fish and snails can be kept in the tank.

2. Wild-harvested plants - water-loving plants collected along rivers, streams, lakes and other banks, and then processed into grass.

3. Bonsai. Bonsai is made by combining moss and flowers. Not many people do this.
