I've ordered from Arrowhead Alpines and Alplains several times, and have always been pleased. Like Lori, I am an active member of the North American Rock Garden Society (NARGS) and the Scottish Rock Garden Club (SRGC). I tend to be more of a seed sower. Alpine seeds can be easy or difficult, depending on the species, and you'll thank yourself again and again (and again) if you keep good detailed records to look back on.
