Q. Is there a way to control or direct the growth of Ceratostigma plumbaginoides - autumn leadwort- in a perennial border?

Planted in border in front of house near foundation as alternative to mulch. Aggressive grower is taking over the area. Can metal or wood footers in the garden contain and direct the growth?

Answer

Your idea of a barrier is a good one.  A metal barrier would probably be the best choice as it won't rot, unless you use a rot-resistant wood like black locust. It should go down at least 6 inches and be a couple of inches high out of the ground.  The plants may try to climb over the barrier but with the use of  a good steady barrier, a lawn edger or weed whacker should keep them in bounds but obscure the barrier.
