Here is a picture from last year ... I need to grab one from this year, as the lizard tail really filled in, and finally bloomed this year.

I do have a water lily, but the pond it shaded for a good part of the day, so it doesn't bloom much. And last year I made the mistake of adding some water lettuce, and that choked out the lily. So late in the year I removed/destroyed all of the lettuce (ensured it did not make it to streams!), and the lily is looking better this year.
I actually got a picture of the pond published in a new book about mini-aquariums! (Well, I guess a 100 gallons is "mini" for a pond ). I also got some pictures of my 24g reef tank in there.
