Here we review the two common species of Water Lily and Commence with the White water lily Nymphaea alba ,referred to as the European Water Lily . It is also known by the names of White water rose, or the White Nenuphar dependent on location.
They are found all over Europe in parts of North Africa and in the Middle East in fresh water. Here in the UK it is probably the largest flower produced by any British wild plant.
This impressive plant has stout underwater stems. The circular leaves float on the surface and may be up to 30 cm across. They are green above and reddish beneath. The large showy white flowers are up to 20 cm across each flower having about 20 petals,the four sepals are green on the back and white inside, they are shorter than the petals. The stamens are prominent and of a yellow colour. The flowers float on the surface and the end of long stems.
The fruit is a globular capsule

The root of this species contains tannin, gallic acid and mucilage. They also contain starch, gum, resin, sugar, ammonia, tartaric acid etc.The root was considered astringent,demulcent, anodyne, and antiscrofulous by herbalists and used against afflictions such as dysentry,diarrhoea and leucorrhoea externally.
The leaves and roots have been utilized in poultices and applied to boils and scrofulous ulcers and inflamed skin and an infusion was used as a gargle for mouth ulcers and sore throats.
Although the roots and stalks were widely used in traditional medicine it is thought that the petals and other flower parts are the most potent. The root of the plant had been used for centuries by monks as an anaphrodisiac being crushed and mixed with wine. Old authors of herbals at that time maintained its use but warned against consuming it in large or frequent doses.

There is a red variety of this species Nymphaea alba 'rosea' which was cultivated from Lake Fagertarn in the forest of Tiveden, Sweden, where they were discovered in the 19th century. This species was exploited to the extent that the species was on the brink of extinction in the wild before it became protected by law. The flowers of this species were red or rose coloured as the variety name suggests.
The white water lily may produce the largest flowers of any British wild plant but this species produces the largest leaves of any British water plant up to 40 cm x 30 cm. The flowers are smaller than the previous species with about twenty tiny yellow petals inside five large sepals.The flowers are sometimes greenish on the out side.
The flowers and leaves grow from a stout and fleshy under water branched stem.The large leaves are thick and leathery. The submerged leaves are more arrow shaped and crinkly. The flowers are succeeded by flask-shaped seed pods which are prominent.
The plant flowers from June until August.
