While I have had no problem 9 years out of 10 with rosemary in NC 7A, I
lost every Bay Laurel I ever tried. I had rosemary survive to the point
the main trunk on several plants was about 3 inches in diameter. Then we
got one of our freak cold snaps which killed the Rosemarys, figs to the
ground (they resprout fine).
Good luck.
