Native to the Mediterranean region, Rosemary has a long history of use. It is said to increase the rate at which blood is supplied to body tissues and therefore to be good for the brain and memory. It can be used with meat, fish, poultry, or game of any sort. Its piney aroma, dark green narrow leaves, and abundant blue flowers make it a most attractive herb. This is the most common variety. Overwintering Rosemary outside: Most Rosemary varieties are hardy down to the low 20's F. A few - Arp, Salem, Hill Hardy - are reputedly hardy down to 0 F or below. Key to overwintering outside is good drainage, some shelter from direct winter winds, and perhaps planting along a sidewalk or foundation to keep the roots a bit warmer. Overwintering Rosemary inside: We generally let our Rosemary's freeze hard several times before we bring them into the greenhouse - some years it has been as late as mid-December before they come in. This gets them to go semi-dormant and stop growing for a spell. We keep them in our "cool" greenhouse as they seem to prefer a cool winter rest period. If put in the warmest sunniest window they will try to grow like it's summer but with the short winter days growth will be leggy and prone to downy mildew. And if they are pot bound they can dry up in a day. Repotting into a larger pot (or root pruning) in September seems to help get them through the winter as well.
