I used a seed mix (very cheap on t'interweb) and sowed with N annual cornflower mix as a nursery crop but no yellow rattle came up so i'm growing some separately. The rest has been a joy for the last 3 yrs
I manage a neetle patch and never let them seed but you have to watch the roots, they run like crazy.
Borage self-seeds like a mad thing and will choke any moe delicate seedlings so pull up as much as you can and chop as much as you can before it seeds
