I brought a number of plants to the swap that I had labeled Mexican Salvia because I couldn't remember their name.

I finally found the original tag and they are in fact Salvia Uliginosa or Bog Sage. "This is a native of Argentina and Brazil. Tall stems with gorgeous blue flowers in summer. Sun. 4-5ft."

They did very well in my garden (Bethesda, MD)last summer and over-wintered well. If you got some, I hope you enjoy it. Here is more info
