Aka Russian sage, although it is not a salvia and did not originate in Russia :-)

Aka Salvia yangii.

Salvia yangii is considered a synonym here (page linked to below). With the way I read the diagram (and comment below) Rosmarinus actually being closer than Salvia clade I (Salvia has been found to consist of three clades - see preceding discussion on same page):

"P. atriplicifolia has been the subject of subsequent studies seeking to clarify the relationships within Mentheae. Further research combined palynological analysis of pollen grains with rbcL sequencing to provide additional support for the relationship between Perovskia and Salvia clade I. It also distinguished between P. atriplicifolia and P. abrotanoides, while confirming their close relationship.[12] A subsequent multigene study (four cpDNA markers and two nrDNA markers) redrew parts of the Mentheae cladogram, making Rosmarinus a sister group to Perovskia.[10]"

"Based upon the phylogenetic results presented here, previous phylogenetic studies, and taxonomic, morphological, and practical considerations, we conclude that the botanical community would be best served by maintaining a broadly defined Salvia, including the five small embedded genera Dorystaechas, Meriandra, Perovskia, Rosmarinus, and Zhumeria as Salvia species. "
Salvia united

Apparently acceptance of the above has not been universal if whoever worked on the Wikipedia entry maintained Perovskia and Rosmarinus. And the included cladogram showed these near but not within a Salvia clade.
