About Borage
Bristly leaves and stems keep deer off, and bees favor the blue flowers over almost anything else. It self-sows hard, so pull the seedlings you do not want early.
Do deer eat borage?
Seldom. Rutgers rates it B, Iowa State lists it in the second tier of herbs, and NC State lists deer and rabbits among what it resists. The bristles are the reason: every leaf and stem is covered in stiff hairs, and a mouthful of borage is a mouthful of wool with a cucumber taste. Under pressure the blue flowers are taken.
Where it grows
An annual in every zone, NC State giving 2a through 11b, 1 1/2 to 3 feet, full sun or partial shade, flowering summer into fall and "self-seeding and will remain in your garden year after year." Bees favor it above most of what flowers beside it. The ASPCA lists borage as toxic to dogs, cats and horses; NC State rates the severity Low, pyrrolizidine alkaloids "that can damage the liver," and the callout below carries it.
Protecting borage
Nothing. Pulling the seedlings you do not want is the only management.
If it is browsed
It regrows from the nodes and flowers on the new growth; a plant browsed in June is flowering again in July, and its seedlings are already coming up around it.
