It is never a good idea to obtain plants from the wild.
Many water plants found in the wild are rare and protected by law.
By removing them from their natural surroundings you may endanger their survival and damage the delicate balance of the surrounding ecosystem. Whenever possible, purchase plants from a local nursery. You can then examine the plant to be sure it is healthy. Check each plant for signs of insects or disease. Remove the plant from its pot and look at the root system.
