Spinach

I usually grow perpetual spinach without to problem. I definitely don’t put it down to any talent or experience on my part.

That will do for me. £1.30 a packet delivered, can't be bad. I'll give it a go.  Strangely it is listed as a chard, but who cares, if it looks like spinach and tastes like spinach plus it doesn't bolt, jobs a good un!

It's descended from the same wild plant as chard (and beetroot) - it tastes a bit earthier and, well, chard-like than true spinach and the leaves won't be quite as tender, but it's a lot easier to grow.
