I presume that you mean it is a little hot where you are to be growing this, Rosemarie. The seed was listed in last (but not this) year's seedlist from the Alpine Garden Society. Those sort of offerings are usually met by an undignified scrum of enthusiasts so it would be a gamble joining just for the one species.http://www.alpinegardensociety.net/
It may not be a succulent but it must be a very specialised xerophyte as it is so dry up there, even when the water is not frozen. Ordinary gentians are famous for their fussiness, this one is probably going to be a challenge.
