Myriophyllum verticillatum , whorl-leaf watermilfoil or whorled water-milfoil , are native to most Northern regions. America, North Africa, and Eurasia. This is very similar to the original milfoil, called milfoil of northern water ( M sibiricum ) Fountain fountains are also easily confused with four types of invasive milfoils: Eurasia milfoil water ( M. spicatum ) , Water-milfoil variables ( M. Heterophyllum ), parrot feathers ( M aquaticum ), and milfoil hybrids (M. heterophyllum X M. laxum < i>).
In many areas it is an invasive water plant.
With the increase in water sports, the spreading of many fountains (Haloragaceae) has increased over the years. The spread of a milfoil is not just in one area, sometimes spreading from one area to another within a few miles.
For untrained eyes, flowering water gods can look similar to other species.

Description and identification
The best way to identify the flowering milfoil ( M. Verticillatum ) is to look at two different types of leaves. The first type is a submerged leave, which looks hairy and contains about 5 to 14 pairs of leaflets per leaf. The whorls along the rod contain about 4 to 5 leaves, which is about 1 cm in length. The other type is known as the leaf that appears. These leaves occur in spikes that appear and pinnately lobes. From June to September, water-based fountains produce flowers and fruits above or on the surface of the water on vertical nails along the leaves that appear. The leaves that appear are usually twice or longer than flowers and fruits.
Another way to distinguish flowering milfoils is to look for turions, winter shoots that appear towards the end of their growing season. This mumoil is one of the few that produces turion. This characteristic can also rule out other types of fountains that have no tursi such as milf MILAISE water, parrot feathers, hybrid fountains, and low water milfoil. The turions of this milfoil look like a long yellowish-green club shoot with small stiff leaves attached to the submerged stems. In the spring after dormancy, small green, thick, and dark green derivatives grow and grow from the stem. As the plant develops roots and continues to grow, larger green summer leaves are produced at the ends of the plant. Turion leaves can be seen at the base of the plant sometime until July. In autumn turion, with some other plant material, often break away from most roots and float to new areas. Those fragments can be found washing along the coastline in late autumn. The stems of flowering milfoil water form into a mat of unbranched and unbranched branches that grow to 20 to 100Ã, inch.

Habitat
Most of the water milfoil that flocked in semi-shallow ponds, lakes, swamps, moats, and slow streams in the lowlands. Milfoil thrives in areas with mild sandy base and medium clay soil. Overall, the plant grows best in calm water with alkaline soil. MILFoil coil water is sometimes found with or near other aquatic plants, such as some ponds ( Potamogeton strictifolius ) and ( Potamogeton ogdenii ), water starch grass ( Heteranthera dubia ) and water-marigold ( Megalodonta beckii ).
Distribution
It's original in most of North America, Britain, Asia, and North Africa, and is invasive to Ireland.
Propagation and reproduction
The MILF fountains reproduce by producing turions between September and November each year. This winter contest sank to the floor floor where they remained inactive until February [Caffrey, 2006]. These fragments will give rise to many small thin roots that become soil to begin growing in the spring. Plants are monoecious (individual flowers are either male or female, but both sexes can be found in the same plant) and pollinated by the wind.
Control and use
MILFoil water screw is a good amount of water oxygenator such as fish pond and frog. It is also ideal in providing protection and respiration for fish seed management techniques of unknown milfoil water, but natural competition with other invasive water plants has been the main control so far. There are several management practices used in some places, but have not been approved for long-term use.
