Hello Moonlit Hare,
borage is a beautiful, but very shortlived plant. So letting it seed around is definitely the best policy. Also, why not collect some seeds to sow in pots? That way you spread the risk of not getting plants next year! Do cut back the flowering stems when you've got all of the seed out of them.
God luck with your overgrown garden, it sounds like a great project!
