Dicentra (bleeding heart)
I'm sure mine had more growth by this time last year. There is a tiny bit of growth, it's just in front of the broken plant label I stuck in to try and point it out.
It's an established plant I've had for a few years that lives in the shade of a variegated weigela in a sw facing border. I live in the north west of england.
Should it be bigger by now, or am I confused with the timings?
