Plants around the pond....

It looks like sage......but can't be...not at your pond side?

No Karen, just checking back had this growing in the garden in 2012....sound advice from Meanie do not cut them back they go through the winter much better, I have a pink one I wonder if that is also from the same family?

Looks like Lobelia (siphillitica maybe, or maybe one of the Fan series). Does it have squarish stems. Sounds like Lobelia if that's the advice that I gave!

Yes Meanie, so pleased I looked back, because I had forgotten!! and would have deadheaded it!!
