Fixed plants are held in place by their roots which grow in the water-bed. The Water Lily and Lotus are such plants. Their stems are long, hollow and light. These stems reach the surface of the water. The leaves and flowers, which grow from the top end of the stems, float upon the water. The leaves are broad with stomata on the top surface so that the water does not block them.
Lotus
The roots of lotus are planted in the soil of the pond or river bottom, while the leaves float on top of the water surface or are held well above it. The flowers are usually found on thick stems rising several centimeters above the leaves. The plant normally grows up to a height of about 150 cm and a horizontal spread of up to 3 meters, but some unverified reports place the height as high as over 5 meters. The leaves may be as large as 60 cm in diameter, while the showy flowers can be up to 20 cm in diameter.
Water Lily
Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on the surface. The leaves are round, with a radial notch in Nymphaea and Nuphar, but fully circular in Victoria.
Banana Lily
The banana lily has floating leaves, but its rhizome is in the mud. The banana lily is frequently found in quiet ponds, lakes, and swamps. It blooms from spring to summer.
Banana lily gets its name from its cluster of thick banana-shaped roots, located close to the leaves near the surface of the water. Banana lily has rounded leaves that have a notch at the base: they resemble small water lily leaves. Banana lily leaves are green above and dull purple below. It has small white five-petalled flowers that arise from below the leaf.
