I'm looking for a rosemary that is winter hardy in zone 6? The rosemary I found here at the local nursery is sold as an annual and says not hardy. Any such thing?

I have had limited luck in my zone 8 with rosemary. Some go for a year or two, then winter-kill. Not sure what it is they want that I lack. Might be a wet foot issue. I just keep trying.

Years ago I bought 2 little rosemary plants on clearance after Christmas from Walmart. I kept them inside for about a year but then planted them outside the following spring. One died but the other one is doing good. Here in the armpit of Arkansas Our Winters are usually not that bad. We do get rain that turns into ice but usually no snow. I think the first year or two I would cover my plants with an old blanket but after that I would forget.

I think the variety 'Arp' is supposed to be the hardiest rosemary. Supposedly zones 6-10, according to High Country Gardens.

Otherwise, I've had pretty good success with overwintering rosemary in a south-facing window... I'd probably have even better success if I was a more reliable waterer Rolling my eyes. .

I have 3 rosemarys - no pics. They are pretty much stalled because of heat, but have been growing since Feb really well. Tuscan Blue tucked in between the butterfly and hummingbird sage and salvia. A prostate rosemary in a raised bed that gets a lot of neglect as far as watering- has trees stealing most of the water they do get, but again these are 'sheltered' or overgrown by the African Blue basil. The third is a twig I stuck in the raised bed that grew and quadrupled in the Spring flooding we got. I love them. I neglected to whack the Tuscan Blue this last fall, so it will get its haircut come this fall. We had no winter this past year- rarely dropped below 70*, but these plants survived our horrid drouth a few years back and are actually doing well.

I have a three bushes, but I sadly know nothing about the specific varieties. I planted two new ones in a raised bed this spring and they are thriving (these depend on me for water b/c they are just outside the reach of the sprinkler system). I had one in the same general location in a pot that froze this winter and never came back. Interestingly, on the North side of our house in the bed near the front door, I have a bush that I grew from a clipping off of the deceased bush before it bit the dust. It has withstood several freezes and it gets regular watering from our sprinkler system. So, basically, my rough data points are this: In zone 7b, rosemary of unspecified variety has the best chance of survival when planted in the ground with plenty of light (indirect Northern or direct Southern), regular-ish watering (good drainage is key), and moderate shelter from wind and freezing during the winter.

I do remember this about that successful cutting--during its first winter in the ground, I placed a plastic bucket over it on the nights when we expected a freeze. Our last two winters have been mild with temperatures dropping below freezing only a couple of times.

My mother has a rosemary bush that seems indestructable. It, too, is situated near a brick wall which provides a bit of shelter from wind and elements. It's located on the west side of her house. I don't think she's ever done anything special to protect it from freeze. This bush and the parent of my oldest successful bush came from Blue Moon Gardens in Chandler, TX. My two new ones came from Walmart. We'll see how they hold up this year.

I'm afraid I didn't really answer your question, but maybe that "annual" rosemary will do fine over the winter with a little shelter?

Rosemary is a tender perennial which means it needs to be protected from cold.
'Arp' is pretty reliable for your zone, but put a blanket on it for the colder months!
With most herbs, think Mediterranean climate & rocky soil!
