How to care for Verbena officinalis var. grandiflora Bampton:
In cold conditions established clumps can suffer dieback if cut back in autumn, so it's best to leave the plant until spring and cut back the old growth when you see the new shoots emerging at the base. Also it's a good idea to mulch around the base of the plant with a deep, dry mulch in winter to help protect the plant.
