Gigantic Knautia Macedonica (Scabious) invasion
Evening - late last year I planted three Scabious (definitely this plant) in front of a rose bush having taken 'advice' from the grower at a plant fair then checking on the RHS site. Year 1 in the garden and it was lots taller than me (I'm 5'6") and taking over the rose view. It needs to be moved no question, but should I attempt to dig up and risk damaging the rose given than the roots are likely to be proportionate to the plant or just collect seed (I have left some seed heads to assist with this quandary) and start from scratch?
Has anyone else transplanted Scabious? Does it mind being uprooted? Is it often over sized? I searched for the exact dark red colour I wanted and don't really want to lose it/them.
What to do, what to do?
