Hi all. I've got a sapling (or half a dozen) appeared between the hedge and shed. I used a plant ID app and it says it's sambucus nigra. Do you think it is? There are no flowers.
Or is it something I will regret? I quite like the fact it's covering the hole in the boundary but not if it's something invasive and going to cause problems. 
Thank you from a v novice gardener
