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 Rosemary varieties.
Plant in full sun. As with the 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 cultivation in California.
Rosemary is native to the dry, rocky areas surrounding the Mediterranean Sea. The name for the genus comes from the Latin name first published by Carl Linnaeus in 1753 for this aromatic shrub means sea dew, derived from the Latin words 'ros' meaning "dew" and 'marinus' meaning of the sea." The specific epithet is the Latin word that signifies a plant sold as a medicinal herb.
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 about Rosmarinus officinalis 'Tuscan Blue' displayed on this web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant. |
