Hi, I have a bush that just started coming up last year in our back yard. (I'm in PA) Right now it has no leaves but it has branches somewhat like a forsythia. From what I remember it has no flowers and long stems with long narrow, dark green leaves. I noticed while cutting it back today that the fragrance coming from the cut stems is really nice, it reminds me of mint and lemon. I know I've smelled it before in shampoos or perfumes. Does anyone know what this is?
