We just bought ours and they haven't bloomed yet, but the plant form looks right for the sasanqua (hiemalis) Chansonette. And the flowers in your picture looks fairly similar to pictures of Chansonette that I've seen.

With the hiemalis designation, I'm hoping for some ability to hold onto their blooms without the flowers shattering too quickly. I'd love to know how the blooms on this one work out for you. Anyway, good luck with whatever it is!

Best wishes,
Mary

Here is a link that might be useful: Chansonette

I do agree with carolinamary : it does look like Chansonnette.

The flowers usualy begin like the first pic, but soon become like the second one, paler, flat and the tip is cup-shaped.
Fanny, the other pink imbricated sasanqua, has much rounder petals. Its leaves are "normal", whereas Chansonette leaves are longer and narrower than most sasanquas, both ends acute and sometimes almost acuminate. The teeth are slightly sharper too, but it's less obvious.
And I'm not sure that Fanny is present in the US :-)
