What is the exact name of this then? Is it an ipo nil or a purpurea? The sepals are upright and it looks that they will remain upright, so is it a nil then?

Here is what it looked like a bit later in the afternoon. Todays the temperature was quite stable. In my mind I have always connected colour changes in ipos with changes in temperatures, but it seems they do change colour anyway.

This is one of the ipos I like best so far, I have had a blue silk, which I also quite like, but this one very much resembles a gentian you would find in the alps, I am sure there are people who mistake it for a gentian or "Enzian" as we say in German.
