Once upon a time, I thought that blue flowers were the natural partner to red flowers.  (Check out the 09/28/10 blog post.)  And Yunnan catmint was the blue-flowered catmint for me, because it's noticeably more tolerant of wet soil and poor Winter drainage.

That was then.  Another color partner is calling for my blue flowers now: Yunnan is gonna move twenty or thirty feet West, into the Pink Borders.  Whew.
