I raise black elderberry, when they flower they look like umbrellas , where as red elders hang in bunches kinda like grapes, so if they hang like grapes are poison, umbrella type black, good wine, from what I can see of your pictures them look like white elder they are good for wine I hear, I don't know where you are from, i'd need a better picture backuped some so I could tell for sure, but in the US those that hang like grapes poison as is the bark as well. but spread out like a kinda like a umbrella good, hanging in bunches very bad, a way to tell about plants if nothing no birds or deer eat it then you don't eat it,
Dawg hopes that helps
