I grew weary of waiting for it to bloom and forgot about it. Hubby alerted me to seeing a new bud yesterday. I almost missed it. They only stay open in the morning. More Nymphoides species info can be seen here. Shops that sell tropical fish are a good source for small floating plants you may desire for container water gardens.
We can always garden inside when it is no longer possible to do it outside. How about a tiny terrarium?
