Rosmarinus officinalis 'Tuscan Blue' (Upright Rosemary) - An erect shrub that grows 4-6 feet tall and spreads 4-5 feet. Bright lavender-blue flowers bloom among the fine, olive green foliage in the winter through spring. Flowers are larger than other varieties. Plant in full sun. As with other Rosemary it is resistant to deer and rabbit predation, tolerant to salt spray, alkaline soils and drought. Hardy to 15°F. This one of the most popular cultivars of upright growing rosemary in cultivarion in California. Recent DNA analysis now shows the genus Rosmarinus to be fit squarely into the massive Salvia genus, which already has about 1,000 species. Since the specific epithet "officinalis" is already used in the genus Salvia, the new name for our common rosemary is now officially Salvia rosmarinus. Joining Rosmarinus in this move to Salvia is Perovskia and the little know genera Dorystaechas, Meriandra and Zhumeria. This change was published in an article by University of Nebraska biologist Bryan T. Drew, Jesús González-Gallegos, Chun-Lei Xiang, Ricardo Kriebel, Chloe Drummond, Jay Walker and Kenneth Sytsma titled "Salvia united: The greatest good for the greatest number" in the February 2017 issue of Taxon 66(1):133-145. For the sake of our customers and ourselves, we continue to list the Rosemary in the genus Rosmarinus!  The information on this page is based on research conducted about this plant in the San Marcos Growers library, from online sources, and from observations made of the crops growing in our nursery, plants in the nursery's garden and those in other gardens where we may have observed it. We also have incorporated comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing Rosmarinus officinalis 'Tuscan Blue'.
