That's really pretty. I've never seen it before. I used to have one with a similar design, but had the white on a lavender background.

Very unusual. It has very large flowers too.

That's really beautiful. I've never seen it before. Keep us posted on how it does through the season.

Gorgeous plant.............I saw one a long time ago that was similar, but not the same, and I believe it was called Apple Blossom verbena. Hope this one continues to do well for you and yes, save some in case it isn't winter hardy. I have to suspect, though, since you got it in South Dakota that it would be winter hardy as it gets mighty cold there.
