The scent of Rosemary is fresh, bracing, and quite invigorating. Reminds me of Pine-scented air fresheners. It has an enticing aroma and it is positively mouth-watering, specially if it emanates from the oven, admixed with the heady vapors of lemon oils, roasted chicken, and garlic. Ahhh!

In spite of the fact that it ranks high in my list of favorite herbs, I do very little with it, actually. I can only think of two dishes: topped on focaccia, and baked inside the chicken recipe I just described.
Hence, I keep more pots of rosemary than I ever need. Most of the sprigs end up as decor on gift boxes in lieu of ribbons - a bundle of fresh rosemary is a visual and olfactory delight, and the recipients can make use of it in their kitchen. Far more use than an ordinary non-biodegradable length of ribbon.
Growing Rosemary, however, is a bit of a challenge. I used to have twenty pots of rosemary, all in a row -and one by one died on me. I think they were severely over-watered.
Now, Rosemary does not like to keep her feet wet. Far from being a dainty creature, it is actually a robust shrub, used to harsh conditions and sparse nutrients on Mediterranean soil. Since I learned that rosemary prefers to be the alkaline side of the pH scale, I added crushed marble stones, easily available in construction supply stores, in the potting mix. This also enhances drainage which is a boon for this dry-loving plants. I'd rather see the plants a bit on the dry side, rather than water logged.
For the past 5 years, I seem to be doing well with rosemary. I found a spot which they seem to prefer - bright but filtered sunlight, and full morning sun. We keep the potting mix loose and well-draining - not a lot of organic material. And we don't re-pot it too frequently.
I figured, after killing a lot of rosemary plants with too much kindness, that this plant actually thrives on a bit of neglect, and suffocates with too much care. As with a lot of things in life.
