This is a fairly compact specimen and is a native of Mexico. It is only around 1m tall with willowy stems holding spikes of lovely slim flowers, of a pretty bright pink colour. It seems to be a summer/autumn-flowering type and enjoys sun. It is attractive grown near to silver foliage plants, such as a shrubby Artemisia or Plectranthus argentatus. It could be grown in a large pot. Cut it back in late winter and fertilise at the same time. Propagate from cuttings taken in spring or autumn. It is frost-sensitive.
Postscript: As it turned out, I never warmed to this Salvia. The flowers just didn't seem to be very striking. I grew it for several years, hoping it would get better, but in the end I took it out.
