These have popped up near our boundary of bush property. There was a plant nursery next door many years ago and when they left they just bulldozed everything into the edge of our property. Trying to find out if these are native or need to come out. They almost look like tomatoes leaves when first come up, but are also growing on a thin trunk, reddish in colour, and leaves are very vibrant green.We have not seen it anywhere else so think a weed from the old nursery??? Most are less than a metre but a couple almost 2 metres.
