Sadly, the only plants rarely damaged by rabbits are junipers, pines and spruce…not much of selection. Spraying the area with a good repellent late into the fall and on any above freezing days in winter with a good animal repellent like Repel-All can often prevent damage. Your burning bushes will bounce back fairly quickly but the others not-so-much. You can surround the shrubs with deer netting in the fall. If you can anchor the netting to the ground the rabbit won’t be able to get through.
