I'd love to know that answer to that myself.
My pink and white ones are blooming right now. I have to lay down on the ground to see the flowers ! lol
I don't remember where I ordered them from. It was years ago, pre-computer days. Whoever it was, they actually called me on the phone and said they'd ship them to me but that they probably wouldn't grow very well here. They did multiply like crazy, though.
