I've always just let borage reseed itself but this year I have a real beauty (3' tall x 4' wide) and would like to save the seeds; however, I'm completely clueless. Does anyone save borage seeds and could you fill me in? Thanks!
Hi tosser - the basic seed saving FAQ should answer your questions. I linked it below.
Basically it is just let the flower heads dry and turn brown, pick the heads and place them in a small ziplock, shake well, sort out the seeds and store them in a paper envelope.
Good luck. ;)
