Elodea Essay -- Papers

Elodea Elodea is a genus of aquatic plants often called water weeds. Elodea is native to North the States and it is also widely used as fish tank vegetation. The introduction of nearly species of Elodea into waterways in parts of Europe, the Australia, Africa, Asia, and New Zealand has created a significant problem, and it is at one time considered a noxious weed in these argonas. Elodea canadensis, sometimes called American or Canadican waterweed or Anacharis (a former scientific name) is widely known as the generic water weed. The use of these names causes it to be confused with similar-looking non-native plants deal Brazilian elodea (Egeria Densa) or hydrilla (Hydrilla verticillata). American waterweed is an attractive aquarium plant, and is a good substitute for Brazilian elodea since it is native to Washingtons lakes, ponds and rivers. American waterweed is usually fairly easy to distinguish from its more notorious relatives, comparable Brazil ian elodea and hydrilla. All of them train leaves in whorls around the stem. However, American waterweed has three leaves per whorl, whereas hydrilla and Brazilian elodea almost always have more than three leaves per whorl. Brazilian elodea is also a a great deal larger, bushy plant with longer leaves. American waterweed also looks very untold like another native elodea, Elodea nuttallii, which generally has three narrower leaves per whorl. The American waterweed lives entirely underwater with the exception of small white flowers which bloom at the surface and are attached to the plant by delicate stalks. It produces spend buds from the stem tips that overwinter on the lake bottom. It also often overwinters as ... ... semi-shade (light woodland) or no shade. It can grow in water. Potting The Canadian Pondweed grows better in cooler water. In temperatures above 70 F, it becomes spindly. This plant can be grown under 8 to 10 feet of water and allow well reach the surface of the average water garden. This plant derives most of its keep from the water through its leaves its roots serve mainly to anchor it to the bottom, therefore, they may be planted in sand or pea berate as well as soil. They may be anchored down and just now dropped into the pond or planted in containers of sand or gravel. If they are only floated in the pond, too much sunlight and air will kill it. If fish dont keep this plant in check, it will carry to be pruned back to prevent it from choking other water plants and taking up swimming space for fish.
