Lucifer is very vigorous.....thuggish. esp here in Cornwall.
I allow a few clumps but watch out for escaping shoots. Very much as Lyn does it seems. Also to keep them in certain areas where I can do tell them. I pot large clumps up too that flower very well. Some varieties are supposed to be less aggressive but I doubt if they actually are. I am unlikely to plant them though.
its difficult to eradicate completely in first year or so but thorough digging will certainly help. the next year be aware of the odd shoots and dig them up....don't just pull them.
