Wanvisa seems to be around 3-4 ft spread, pads will mound up a bit above water when it feels crowded, & it is a moderate bloomer. The color & look of the pads adds nice texture to the pond while you wait for a bloom to pop up. You can see my grow out plants at the end of my big wood pond & how the pads are mounding up some. It will be interesting to see how it behaves in a mud bottom pond where it can really stretch out without limit.
And yes, I'll be offering Wanvisa either later this summer or in the spring. Depends on how many tropicals I boot out of the ponds to make grow out space.
