There are 2 different miniature species: N. pygmaea and N. tetragona.
Yes, Craig said it's a Nymphaea pygmaea.
To me, it looks exactly the same as an N. tetragona,
but Craig knows the difference, not me.
Craig also grew some of my seeds too,
so he has seen my plant himself.
All I know is that my plant blooms best when it is not too hot.
When it gets hot, the blooms slow down drastically.
It has bloomed as early as April, and as late as October.
I pulled the plant up out if the pondsai early last April and it already had buds on it.
