Late planting of potatoes?

I've got room for a few more buckets, and I was thinking of potatoes... reports of shortages later in the year have got me thinking  I'm not specifically aiming for the winter festival that can't be named 

Which varieties would actually produce tubers if planted in the next week or 2? I've no experience of planting this late in the year, but have the greenhouse if they need to be moved inside later.

Oooh I’d like to try this… hmmm,might have to scour some garden centres (or DIY stores!) to see if there’s anything suitable. Maybe Charlotte?

I recall that one year DD didn't manage to get his until June. Maybe this thread might be of help:

Thanks, you have a better memory than me, obviously   

If you dug a charlotte potato up growing now and planted that would that work?

The Potato House keep sending me adverts for spuds to plant now and harvest at "that time of the year" - don't know why as I've never used Potato House but that's by the by. They are recommending Charlotte and Nicola (2nd earlies) and Jazzy (1st early). I've just planted a few more Maxine (2nd Early) left over from last year as a trial. They are in the ground so I may need fleece or whatever later on. Worth a try anyway.
