I planted this plant in Oct 08. It is in a well drained bed. Didn't grow much the first year. This last year it has grown approximately 1 to 1 1/2 ft. It survived the 110 plus temps we've experienced the last 2 years. It gets approximately 6 hours of direct sunlight a day, late morning till dusk. It will survive some drought conditions but it does beautifully with daily watering and weekly deep watering. And the fragrance is wonderful. Use this in cooking and bbq in moderation.

I have a Tuscan Blue in Memphis, TN and it is a great plant for this region. One tough plant that shrugs off the intense summer here easily. 5' tall and wide, I believe it would be 8' tall if I didn't prune it yearly. This plant is about 7 years old and was huge at 4.

Tuscan Blue Rosemary is seen all over San Diego,CA.
I have 7 of them. They love alot of water and adapt perfect to the Southern California climate. My neighbor has one in her backyard that is about 5 feet tall and 4 feet in width. Great plants. Another good thing is that, Cats hate the odor of Rosemary and will not go within an area where they are planted. It keeps them away from your house windows and prevents them from spraying.

I just planted this last year and it is already 2 ft tall and about 18" around. It smells great. I've made a number of cuttings and they re-rooted easily.

I've seen this get up to a bit over four feet in my garden, and around three feet wide. It grows quite upright, with straight long stems. It blooms profusely with blue-violet blossoms much adored by bees.

Culinarily it is a good if rather strong cultivar; I prefer other cultivars for many dishes because their flavors are a bit more complex and the leaves are softer and easier to deal with if they are not going to be removed at the end of the cooking. Where it shines is laying sprigs under meat when roasting it, putting them into a marinade and removing them later, or even stripping most of the leaves from woodier stems and using them as skewers.
