I am looking for a purple and white variegated Heuchera. I have a small tropical waterlily that I have to trade. I don't know the name of the waterlily, but I do know it has a blue flower.

This is a small waterlily, the tuber is about the size of two quarters, so I am only looking for a very small piece of Heuchera. The type of Heuchera I am looking for are similar to: Heuchera: silver bells, plum pudding, velvet night, can can, or Geisha's fan. Pictures can be seen on this website I came across http://www.bergmannurseries.com/Heuchera.htm

Thank you very much.
