unknown giant

Any ideas for the name of this plant that sprouted up between brick paving beside my greenhouse ? The stem is very woody and the flowers resemble green thistles but soft.

 

Burdock?

 

Thank you very much, of course it's Burdock, should have known. All that Dandelion & Burdock fizzy I have drunk, perhaps I could make my own.

 

Welcome to Gardeners Corner Lynda MBE,

If you can get the root out, yes. They grow upto a metre long and can be as thick as a baby's arm.

I make my own Dandelion Coffee, might try blending it with that.
