Now this is a blue Salvia!
The Gentian Sage (Salvia patens), native to Mexico and Guatemala.

I grow salvia patens and people point from the other end of the garden, "What's that lovely blue?"

Sage is so pretty! There is Russian sage growing in the Pacific Northwest and I love it because when it blooms, the blooms last for a very long time!!! This Blue Jean Baby Sage looks just like it!!!

The genus Perovskia, like the genus Rosmarinus and several others, is now included within the large genus Salvia.
The new name for Perovskia atriplicifolia is Salvia yangii. However many garden plants are likely hybrids between Salvia yangii and Salvia abrotanoides (formerly Perovskia abronatoides).
