Plant ID - longevity spinach or garlic weed?

[kumquattish]

We have a plant that's about 5-6 ft high, for ages I assumed it was part of a bay tree, but I realised tonight it might be separate. I put it through the plant app, and it said gynura procumbens (longevity spinach) or petiveria alliacea (garlic weed). What does MN think?

Bump!

Petevera alliaceae according to google is tropical so wouldn’t grow outdoors in the uk. Gynura procumbens is from Asia and is not readily available in the UK, so how would it have got into your garden? Procumbens means trailing or creeping - everything in the picture looks pretty self-supporting.

apart from the toothed leaf at the bottom, which part of that picture do yo think is not bay? Have you tried following the branch down and seeing where it starts from?

Thank you for your reply. The toothed leaf is a mahonia. The leaves above are what I thought was a bay, because there are two enormous bay trees next door close to the border. But I compared the leaves this week and thought they weren't sufficiently similar to the bay. It's hard following the plant as its roots are either right under the border fence or on the other side. Does that indicate it's part of the two enormous bay trees next door?

They look like young Bay shoots.

What do the leaves smell like?
