Nymphaea Stellata Aka Dwarf Lily Bulb is a beautiful and fascinating aquarium plant. These plants are hardy and great for beginners, it will continue to grow and send runners out which you can then propogate. You are able to plant them elsewhere in the aquarium.

You can throw the bulb in anywhere in your aquarium, or plant a quarter of the bulb into the substrate just to help hold it down.
Do not plant the Bulb entirely.
