Vallisneria americana, commonly called wild celery, water-celery, tape grass, or eelgrass, [2] is a plant in the family Hydrocharitaceae, the "tape-grasses". V. americana is a fresh water species that can tolerate salt, living in salinities varying from fresh water (0 parts per thousand) to 18 parts per thousand, although the limit to the salt tolerance is unclear, and is generally dependent ...
Vallisneria will accept neutral to alkaline water conditions (they do not like very acidic conditions) and do not require carbon dioxide fertilization. They are also among the few commonly traded aquarium plants that tolerate brackish water, provided the specific gravity does not exceed 1.003 (around 10 percent the salinity of normal sea water ...
Vallisneria spiralis, also known as straight vallisneria, tape grass, or eel grass is a common aquarium plant that prefers good light and a nutrient rich substrate. In the wild, it can be found in tropical and sub-tropical regions worldwide.
Aquatic plants are used to give the freshwater aquarium a natural appearance, oxygenate the water, absorb ammonia, and provide habitat for fish, especially fry (babies) and for invertebrates. Some aquarium fish and invertebrates also eat live plants. Hobbyists use aquatic plants for aquascaping, of several aesthetic styles.
Vallisneria spiralis is an example of hydrophily. Female flowers reach the water's surface temporarily to ensure pollination. Hydrophily is a fairly uncommon form of pollination whereby pollen is distributed by the flow of waters, particularly in rivers and streams.
Water celery is a common name for several plants and may refer to: Oenanthe, primarily: Oenanthe javanica (Apiaceae), native to eastern Asia; Ranunculus sceleratus (Ranunculaceae), native to North America, Africa, Europe, and Asia; Vallisneria. Vallisneria americana (Hydrocharitaceae), native to North and South America
There are crops that can grow on seawater and demonstration farms have shown the feasibility. [1] The government of the Netherlands reports a breakthrough in food security as specific varieties of potatoes, carrots, red onions, white cabbage and broccoli appear to thrive if they are irrigated with salt water.
As the water body becomes shallower, more submerged rooted species are able to become established due to increasing light penetration in the shallower water. This is suitable for growth of rooted submerged species such as Myriophyllum , Vallisneria , Elodea , Hydrilla , and Ceratophyllum .
