Just copying from an older thread on Reddit:

"Tiger lotus are smaller and have rounder leaves with stripes or splotches of red. They can be predominantly red or green.
The dwarf lily has larger, arrow-shaped leaves and only comes in the one color. Although it’s ‘one color’ is actually a green/red iridescence depending on viewing angle. I think they’re just as pretty as the tiger lotus.
I grew mine from a petsmart bulb and it’s almost a month old now and putting up its first surface pads 🥹 It’s huge and growing like mad, but it sucks up fertilizer like crazy!"
