Interesting re your species, Rita.
Seems a safe bet for your growing conditions.
May try it myself.
Not sure about the "naturalization" of alien species.
I'm assuming the problem is that the checks and balances between species, in the native ecosystem, are lacking when one species is placed in a non-native environment.
I also assume Chionodoxa forbesii is going to prove to be one of those few run-away alien plant, though I haven't seen it moving into the extensive conservation areas around here (yet).
