Identification of Plant/Shrub
Hello, everyone. This plant/shrub appeared in our front garden - I used to nip it off when shoots first appeared then decided to let it grow to see what it looks like - it may have spread from an area under one of our conifers; it does seem to be invasive, as I've noticed shoots elsewhere, and it grows fairly quickly. It is about 3.5ft in height. I hope it isn't JK... the nodes don't appear to zig-zag and the stems aren't hollow.
