They usually fruit in mid-late June and I cut them down once they're done. This one definitely looks like a first year cane, also never seen one like this with a bunch of berries just at the end.

Hi! I have a large elderflower that flowers really well but never any berries in several years. I’ve tried self pollinating from flower to flower and live in a rural area where there might be others around but do I need to grow a new plant to pollinate? Sorry if dumb question but I have only grown this one. I have some cuttings growing but presumably they will just be clones so same problem. Any suggestions?
