介于Rusian Sage / Catmint 之间, 花期很長

It's from a picture from Davia Austin Garden Center. It's not catmint, levender or Rusian Sage. I have all three. This is something taller than catmint, about 2-3 feet wide and a foot and half tall. It is much softer and fuller/more dense than Rusian sage. It has better forms and the flowers are brighter too. I bought rusan sage at the end of last season, thought it is what I was looking for. Only to find out it is not. It blooms from spring to summer. really pretty. I really want to get it. I was researching rose yesterday and saw the picture posted by jansondad(?), I immediately noticed that's what I wanted for quite some time. It can be used in a more structured landscape or pair with roses. 

Thanks for replying, thanks for the picture. Sorry for the English. I need a little bit of luck to get chinese keyboard. (shift/alt. only works sometimes)
