When deadheading Lupins, where does the second fgrowth of flowers come from - the same stem or a new stem?
I have read that by cutting the faded Lupins back to ground level, a new growth of flowers will emerge.
Is this a whole new stem emanating from the crown, or from the same stem? I had alwasy believed that to prompt re-growth it was neccesscary to cut to a bud, but if you are cutting below the flower spike there are no buds.
