Plants – Water Lettuce/Pistia


I have a pond filled with a late summer carpet of Water Lettuce. Water Lettuce, or Pistia, is an aquatic plant that can be grown in aquariums or in outdoor ponds through the summer. Water Lettuce was first discovered in Africa. The rosette-like leaves float on the surface of the water with the roots growing from the center of the plant.


Water Lettuce outcompetes algae for nutrients and thus helps control excessive algae bloom.


The mother plant is connected to her offspring by a stolon. The plants reproduce so quickly I have had to weed out half a dozen or more several times this summer. My plant came from the productive water lettuce plants in my sister’s pond.


As I was surveying the water lettuce yesterday, wondering if it was time to weed out a half dozen again, I noticed a small frog. Grown from a tadpole we captured in a local lake this year, he quietly watched me, deciding if he needed to jump for safety. He stayed quite still as I took a few photographs, but when I brought the camera a bit too close, he jumped beneath the cover of the water lettuce leaves.
