Plant ID please

[Chrispy]

Can anybody tell me what this is please?

It looks very much like a tomatillo plant to me.  And they're edible

I agree with Squeezyjohn, looks like a tomatillo to me too  They don't self-pollinate, so you'll need another plant or two or a neighbour growing one nearby.

Thanks Guys, that makes sense.

They are on a friends plot, it's a case of lost labels, but she swears that they must be peppers or aubergines, as those were the seeds sown.

When I see her next I will ask if she has ever tried tomatillo and see if the penny drops.

There are 3 plants so that is fine for the pollination.
