Hey guys,

This little guy popped up a few months back. Is it a wild olive or weed?

Looks like an olive to me but I'm no expert

Looks like olive to me. I have had a few pop up in my yard too

100% that looks for all the world like an olive... just popping up in Melbourne... you been composting your Greek salad leftovers??!?

It has all the hallmarks of olive.
More people putting olives in as fruit trees or as ornamentals, even in city blocks as the ttrees are relatively small. Birds love the fruit so more and more seeds are dropped each year.
Adelaide has a massive feral olive weed problem. As the weather gets warmer and drier it suits olives and we are also starting to see them become more and more of an invasive species.
Olive seedlings grow and thicken quite slowly so now worth starting from seed/ seedling if you have access to older feral trees.
