Thank you Lesley & Aunty - I think red goosefoot most likely from the way flower buds are forming, but I‘ll heed Lesley’s warning and wait for the flowers to come out to be sure.
From what I’ve now read about goosefoot, like other greens once it bolts the leaves turn bitter so it won’t be a useful leaf crop now, if that’s what it is. I got excited that the seeds can be harvested as wild quinoa, but the difficult extraction process hardly seems worthwhile. Interestingly the seeds are also said to contain a lot of saponins though, so if it turns out to be this maybe a home made soap or cleanser might be possible

Thank you again for responding.
