I trimmed one of our bushes significantly. Everything I cut out was dead or very near dead branches. I think it was killed by someone parking a vehicle with the exhaust pointing straight into it for a year or so. Regardless, I got tired of looking at dead branches so I cut them out. Unfortunately this is what we're left with and I'm not sure how best to deal with it. Can someone please ID what this bush is? Can I expect that it will fill in this giant gap? If so, how quickly is it likely to fill in this area? Or should I be looking to purchase a smaller plant of the same species to fill in this gap? Please give suggestions on how to make this eye sore look better.
