we had a strange winter this past year which wiped out about half of my perennial herbs.
the very warm december and january was interrupted by a sudden, deep cold spell. then it was back to unseasonable warmth, then more quick drops in temperature. since the plants didn't harden off properly, many of them were shocked and froze to death.
i lost all of my english and lemon thyme, flat leaf parsley, and half of my silver sage, mint, and rosemary.
fortunately, there are new shoots of sage and mint coming up, and the remaining rosemary plant is doing well, so i'll have a good amount with which to cook.
i replanted the flat leaf parsely and cilantro from seed, and i have to pick up some thyme seeds or plants when i get the chance. also, savory seeds or plants.
other than that, i've planted sweet basil, garlic chives, and chervil.
