Salvia rosmarinus Schleid. was named and described by Matthias Jacob Schleiden in Handbuch der Medicinisch Pharmaceutischen Botanik in 1852. So, it is not a new name, it has just been resurrected due to phylogenetic testing.

Now a synonym after so many years, Rosmarinus officinalis L. was named and described as such by Carl von Linnaeus in the first volume of the first edition of Species Plantarum in 1753.

Plants of the World Online lists 1,015 species in the Salvia genus (as of 2-14-21 when I last updated this page). It is a member of the plant family Lamiaceae with 236 genera. Those numbers could change as updates are made.

This was a very interesting change of events. Carl Linnaeus classified Rosemary as Rosmarinus officinalis in 1753, but Mr. Schleiden attempted to rename it Salvia rosmarinus in 1852 and he had a good reason. Apparently, that didn’t go too well because Rosmarinus officinalis remained the accepted scientific name for a very long time.

In 2015, I think, testing revealed that plants in the Dorystaechas, Meriandra, Perovskia , Rosmarinus, Salvia, and Zhumeria generas were all equally related. 

Brian Drew and others proposed the species all be put in the same genus. Besides the genus Salvia, there were only 15 or so other species affected and they could easily be renamed with Salvia as the genus name. Moving or reclassifying the Salvia genus would have proven to be a nightmare as there were 1,010 accepted species of Salvia (as of when I updated this page on May 24, 2019). There was already a Salvia officinalis (culinary sage), so the name proposed by Matthias Jacob Schleiden in 1852, Salvia rosmarinus, was used for the Rosemary. It took time for the document for the change to be published, approved, and the changes to be accepted…

I decided to plant the Rosemary in the southeast corner bed. It would get plenty of sun and the bed is kind of on a slope so there will be good drainage.

According to information online, Rosemary is evergreen and cold hardy in USDA zones 7a-10b. Well, we are in 6a but you never know. It just depends on the winter. Rosemary can be grown inside during the winter as a houseplant if certain “rules” are followed. They need plenty of light and good air circulation. Poor air circulation can result in a few problems all indoor plant people want to avoid… Some of the links below provide plenty of useful information.

The Rosemary did very well and started growing with no problems. I planted the Oregano in the same bed with Marigold ‘Brocade in between them. I have no idea where the Talinum paniculatum (Jewels of Opar) to the right came from…

Salvia rosmarinus at 23″ tall on 8-20-17, #367-23.

2017 was the first year I planted the Marigold ‘Brocade on the south side of the house. I have been growing this series of marigolds for many years but it grew MUCH, MUCH larger than I expected there. When the above photo was taken, the Rosemary was 23″ tall. The Marigolds were almost as tall, and in one spot the Marigolds grew to almost 36″ tall and wide…

After several frosts, the Rosemary was still green while most of the other plants were dead or dormant. Well, it is an evergreen, right?

Clear through December the Rosemary stayed green and continued to grow.

January was a cold month in 2018 where we had several below zero days, even down to -10 a few times. Even though the leaves on the Rosemary changed color, they stayed firmly attached. I thought maybe it would survive

I checked the leaves as I was taking photos on March 9 (2018) and the leaves were brittle and fell off to the touch. The roots were not firmly attached to the soil either. So, I guess that means this Salvia officinalis is no more…

The link below to the Wandering Botanist takes you to a great post titled “What Happened To Rosemary”. It is very interesting.
