I clean out my water containers every Spring. This year I found these odd looking things growing in the pots that my waterlilies are in. Are these baby waterlilies sprouting from seeds? I've never seen this before, but had quite a few of them as you can see. They were growing inside the pot among the roots of one waterlily as seen. And also in the photo you can see a pile of them that I pulled out of other containers.
