Anyone know what this is?
They are growing next door and starting to pop up on our side of the fence too all over the place. Assume it is a weed and we should encourage the neighbours to get rid of it...
Even more worried now. I saw this yesterday when walking by a creek. It's actually a tree. Anyone know what it is?
Wow, that is a lot worse than I imagined @robchin. I will definitely talk to my neighbour ASAP. I remember Ricin from Breaking Bad!
Thank you so much for your help.
Thanks again for your help @robchin. We've pulled out all the plants we could and poisoned the roots of those that we couldn't completely yank out and just had to cut off at ground level.
