Thank you Lynn, I´m going to give it a few weeks more outside before I take it to the greenhouse.
The Rhodiola rosea is very comon here as a native plant, I have a few in Jarphagi, where my summer cottage is. The Rhodiola semenovii is there also, I found it a couple of years ago, maybe a gift from a friend, but I don´t know who. The photos are not very good.
