  Lotuses only blossom for three consecutive day. They blossom in the morning and close together in the noon every three days, but don't join together on the third day. However, water lilies can blossom up to 7 days. Some water lily species blossom in the morning, but some in the afternoon. Here are the differences between lotuses and water lilies.


[Lotuses are like sleeping beauty] by Jing-jia, Chi-lin and Zih-wen

       Water lilies blossom in every season. The fragrant water lilies in winter are very aromatic. We found this aroma is from the ovary.

       The fragrant water lily is a floating-leaved aquatic perennial herb that grows rooted in mucky or silty sediments in water up to six to seven feet deep.  Mature leaves have long stalks and adjust their curve to keep sticking on the surface of water.  The leaves float on the water’s surface, maintaining their position, even if the water rises, by continuing stalk growth.

          The one in the third pond was pink water lily surrounded by purple lilies. It blooms on or slightly above the surface of water. After wilt, the stalk bend down and the flower gets into the water. The fruit in the flower will grow in the water. Our teacher said that the fruit will be black when it's ripe.

We wrote a report about the differences between lotuses and water lilies, as follows. 

 
  
The leaves of water lilies are right on the surface of water, however, the stalk of lotus leaves stand straightly above the water. To tell their difference by leaves is a simple method. However, when water lilies are too crowded, they still look like "standing" as being pushed by other lilies. There are still other characters to tell them.

1. Water lilies have a breach on the edge of its leaves. Lotuses don't have any breach and
       wavy.

2. No matter what kinds of lotus, there must be a structure called Seedpod of the Lotus which  
    is surrounded by layers of petals. Water lilies don't have any
Seedpod of the Lotus. When a
    lotus starts to fade, the petals fall down one by one while
Seedpod of the Lotus is still
    growing. Water lily has an interesting fading way,  which makes whole flower sink into the
    pond and fruit inside.

3. As for the colors, we can just find only pink and white lotuses no matter how good the
    gardening tech is. However, there are lots of colors such as yellow, purple, pink, white, blue
    and etc.

 4. As for the function, the food we have is from lotus such as seeds and rhizomes. The colors
    of water lilies are different as well as the fragrance. Allegedly, the best aromatic type of
    Fragrant water lily is yellow type. It can be made tea.

      There are some lotuses in the forth pond. Water lilies are  nymphaeaceous, but lotus belongs to legume. They are similar before they blossom but really different after they blossom.
