Viviparous Form Issues
There are several varieties of Tropical water lilies that have a faculty known as viviparity, or the ability to bear their young alive. This is a site that every water flower will love to behold. A leaf of a viviparous water lily becomes mature, a bump will form at the umbilicus, the place was the stem and leaf joins. The bump will break after a few days, where the small leaves begin to form, sometimes growing to the size of a silver dollar. Sometimes, depending on the parents, a perfect miniature of the parent will bloom!
Winter Care
Storing your water lily roots during the winter is a simple and easy process as long as you follow these guidelines. Make sure you store your roots in a place that is cool and dry, like a cellar or storeroom. Roots are a favorite for mice and rats, so make sure the area where you store them is pest free, or place them in metal containers with holes punched in so air can move through.
You can also choose to carry the Hardies through the winter. You can do this by removing the bricks or stones that were placed under the plant receptacle so the boxes drop to the bottom, keeping them well below the frost level, allowing them to safely survive through the winter under the water. The roots will only be harmed if they are frozen in ice.
If the frost line is really low in your area, it is best to cover the pool with boards. Cover the board with leaves, evergreen boughs, straw or some other convenient insulation. It may be best to store them inside, simply take the roots out of the boxes, clean them, and trim off excess roots and stems, then store them in clean and dry sand.
