Crinum thaianum is a distinctive bulbous plant belonging to the lily family. It is undemanding apart from the fact that it needs plenty of space. Plant so the top 2/3 of the bulb is visible, because otherwise the bulb tends to rot. When the plant grows older it sometimes sends a flower stem up to the water surface with an aromatic, elegant lily flower. Herbivorous fish leave it alone due to its tough leaves. In Thailand the bulb is used in a cream used to soften the skin. It is also suitable for indoor ponds.
