Each plant is around the size of your hand. You can cut these into multiple pieces. As long as there's a leaf on the stem you can cut it there and replant it into the substrate. You could also lay it down and it'll grow shoots up from every leaf. You could fill your hole tank if you wanted to. At night each leaf closes up. In the morning they open. The leaves have a purplish hue on the under sides. I'm asking $10 for 8 stems. Cash is best. I don't have any of those apps. I also have a few other plants you may be interested in. Thanks for taking a look.
