I know, sounds like a spell from that boy Harry Potter!
I think I have one of these. This year it has grown rosettes of very large leaves but no flowers. On Google it says it is highly scented with daisy-like flowers which match the picture I have - on a seed packet. What I would like to know is is it a thug, If so how much of one. Should I keep. or dig up?? Any other information please.
Another name I think is Heart leaf Telekia
