What is growing in my back garden?

[Twims]

what is this growing in our garden? It is at least 4.5ft tall going on 5ft in height. It has large leaves almost like rhubarb but doesn't look like the rhubarb we have growing else where. Any ideas?

yikes

it is a triffid

I think it's Jacks beanstalk - just waiting for the golden eggs

Has anyone gone missing from your household?

it looks like perpetual spinach gone to seed...

or may be swiss chard.

Don't think it's Spinach as it sounds like they grow to only 30cm or so and this is nearly 5ft!! could possibly be swiss chard - but we didn't plant any!!

Looks like burdock-hard to tell from pic-but fits your description-does it have purple flowers/burrs on it?

No purple flowers or burrs

can you do a closeup of the leaves and flowers? Its really hard to tell, tbh, without those.

tbh just looks like chard or spinach gone to seed.

perpetual spinach can grow up to 5ft if its left, so can chard.

I figured out that if you click on the little pictures you get a bigger picture-with a lot more definition. But I still don't know what this is and it's bugging me because I have seen this plant.

im sure its perpetual spinach...

is it this...?
