where grows the edelweiß?

my first day at work (still in the office, 'cause internet still doesn't work at home) and my first request: an american guy called to tell me that he is planning to do a "sound of music"-performance. therefore he desperately needs edelweiß, but doesn't know where to find one in the States. big problem, 'cause Lauri didn't know either -but thank Google and my workmate --> there is an edelweiß farm in Canada: http://www.edelweissgrowers.com/
