Ballota pseudodictamnus

This is one of those plants which always looks terrible in pots, it is however a good garden plant if correctly maintained.
Ballota needs to be pruned at least twice a year to keep it compact and bushy, the foliage is on the sage green side of silver. It is a summer flowerer and they are not a great feature but Bees go crazy for them. Once established this is a tough plant for full sun. I keep mine pruned at around 60cm both ways
