PUSHING THE BORDERS

I know I've asked about the ID of this plant on the old forum but have forgotten again :roll:
It is a hardy herbaceous perennial that grows about 60cm tall and spreads slowly.

Thanks.

Lobelia laxiflora 'Angustifolia' Andy. Lovely thing that seems to flower continuously throughout summer. It used to run about a lot here often with Freesia laxa 'Grandiflora' popping up through it - wonderful combination. I needed the space for something else and dug up loads to pot up and donate to the local school fete. Unfortunately I was too efficient and didn't leave any for me :roll:

Thanks very much Dave, I never would have remembered that it was a lobelia. The only thing that pops up through my clump is horsetail.
