I was unsure about growing rosemary in Spokane (zone 6b), but have had great luck with Rosemary Arp. I have tried other varieties but none have survives our winters. I planted two arps in 2016, one is in a somewhat protected spot and the other is in a more exposed location. I protected them with blankets for the first couple of years when temps dropped into single digits, and they survived with only a few brown tips. Both plants are still alive, large, and very healthy!

In zone 7b/8 Memphis, mine wintered over fine for two years before the unusually cold winter in 2013-14. It looked like it died last winter, but the plant actually survived. I had to cut it down to bare stems about 10 inches tall to get past the dead parts, but it has regrown nicely (and in a better shape) since spring. This winter is also expected to be colder than normal, so it will likely take a hit again. It is planted in a raised brick garden about 2" above ground level, but is shielded from north and south winds by houses. Somewhat sheltered, but not entirely. Gets lots of afternoon sun. I have seen rosemary planted as foundation hedges around town. With our Memphis clay soil, I'd recommend amending the soil with lots of sand or other material to facilitate drainage and planting in t... read more

'Arp' has good scent and flavor, and is reliably hardy in the Washington-Balto. suburbs. In my experience it needs to be replaced after 5-7 years as it begins to suffer significant winter damage when it gets big/old enough.

In October of 2010 I planted a #1 size pot of 'Arp' rosemary in a large planter along with some ornamental cabbage. The end of November brought us a severe cold snap that plunged our area into low single digit temps. for 2 to 3 nights. Amazingly this cultivar was unscathed by this freeze that has caused much damage to plants around our area. Plus one for 'Arp'.

About 10 years ago bought a rosemary plant off the sale table just for the summer. It survived much longer than I expected then 2 harsh winters finally killed it. Replaced it with the 'Arp' strain which (according to the vendor) is more winter-hardy. So far it's doing very well. Pretty flowers and to me tastes the same.

This hardy rosemary is by far the most reliable variety for western Washington winters. I have multiple 'Arp' plants and have never had notable winter damage on any of them even through nasty excessively wet and cold winters.

These are strong shrubs that do get large with time, take well to pruning and are incredible as a culinary rosemary. I have found that some 'Arp's are inclined to grow at more of an angle than some other rosemary plants and, if left to their own devices, with age frequently take on more of a sweeping form than a ridge, upright one.

We love this plant, which grows beautiful in the sandy soil here in Lewes, DE. Ours is used as an informal hedge in front of our porch--running along the sidewalk--and almost everyone who walks by rubs the foliage, releasing the wonderful scent. This past year the plants bloomed exhuberantly, first from early November thru much of January, then again from late February through March (with some blooming even into April). Many neighbors in town commented on it! The soil where we planted them is almost pure, unamended sand, which was what was left after our house was built. Except for the first summer, we don't water them at all. The picture I've posted is a couple of years old; they are now at least two or three times that size (i'll try to remember to post a new shot soon). I show a view ... read more

Many rosemarys do not winter well for me. I put arp in a very sheltered , well draining site with a cloche and it overwintered just fine. This winter also had a few severe (in the 10s and teens is severe to us) cold snaps. I recommend it for people who have trouble overwintering rosemary. It is a little slow to recover after winter damage but does just fine. :)

This is an annual here in zone 5 but it's worth getting each year for the uses it has in the kitchen. It can also be brought in to over-winter in the house, in a sunny window. It makes a great seasoning for Italian foods and is greatly aromatic in homemade potpourri.
