Which Calandrinia?

[Gerdk]

I received this Calandrinia via NARGS Seed Exchange as C. colchaguensis and as usual
(from all sources) it never came out as the true plant.
Nevertheless this is a most beautifull species and I would be glad if a had a name for it.
The plant survived outside during two winters here.

A beauty, Gerd - I hope it stays with you. It may be Calandrinia umbellata?

[Gerdk]

Thank you, Maggi! That was really quick and exactly right.
According to Google pics perhaps the cultivar ' Ruby Tuesday '.

There are  photos of Calandrinia colchaguensis - both in the IRG 51 of March 2014  and a newly published as a supplement to that issue.

A fortunata error. Mostly the opposite occurs. What a stunning plant Gerd.
And Maggi, you are quite right with your determination of this Calandrinia umbellata
