Didn't know I had this one. Got it as a mystery tuber 2 years ago, and here she is blooming. Think the super warm water in the fish tank got her going. I teased dh if he din't get the tank set up, I was going to stick a lily in it. I did and look what happened. Its now in the pond.
Funny thing is, I went out yesterday morning and saw a white bud opening. I waited about and hour and went out in hopes it would be open all the way. No, it was closed tight. I stopped and said that's weird. Then it clicked that it must be a night bloomer, sure enough it was. Has another bud on the way too.
