we've found a couple of these growing in our garden veggie patch. when small they looked similar to our potato plants however now they're much bigger they don't look anything like potato plants. we've had a lot of seeds move round the garden caused by the wind, animals etc. to the extent of a patch of our lawn being full of parsnips! so i don't want to assume this plant is a weed and just dig it up to find it was actually something edible. i don't want to leave it if it is a weed as it's taking water and nutrients from the other veggie plants. please help!
hopefully the pictures help (coming soon) but the plant has red stems and stalks. leaves are green with a slight purple edge. there are 3 separate leaves on each stem.
