Q.Unknown Seedling
I have a barrel in my garden that I am growing vegetables in – I ran out of seeds though and I ended up only planting cabbage and sunflowers in the barrel. Somehow another seedling is growing – is it a weed or a vegetable i have forgotten about?! It doesn’t look at all like a cabbage seedling and it does look similar to the sunflower but doesn’t quite look the same/ have the same texture. Any ideas? Thanks in advance

Oh no! Thanks for the heads up! There was me thinking it was a vegetable ? better get that sorted pronto!

This appears to be Bindweed.
