I am in Augusta County, Virginia and planted it this spring for the first time. Planted 1/2 acre as an experiment. Did lime it twice before planting as my soil has a low ph. Unfortunately, my area has been extremely dry. Grew about 4-6" tall and looked like it was dying. Rain recently, and it looks like it is going to survive.
I hope it will bloom this year. If not and it survives, I hope it comes up as a strong established plant next year.
I am interested in knowing whether or not anyone else has tried it and what their results were, also.
Even though my sainfoin has not done well, it seems to be a favorite place for the local deer.
