Have jus seen F1 totem tomatoes growing in pots at our local train station.
Looking it up on the internet i've seen there are also seeds called
*Ferline* F1 hybrid-1.

All very confusing for a novice. We want to grow these container toms on
our patio (south facing in north london).

Which are the best ones to go for please? Have we left it too late to have
a go at it this year? Thanks.
