I have been following a garden forum where, currently, one of the most talked about dwarf tomato plants is one named 'New Big Dwarf'. It is actually a very old variety. If grown in a big pot, it resembles a determinate growth habit; if grown in the ground, it keeps producing. Produces 8 to 14 oz pink tomatoes. One of the main attractions for me is it is a stocky, sturdy, not too tall plant. I'm also trying a really tiny dwarf, Hahms_Gelbe_Topftomate, a yellow that reportedly produces heavily, even when grown in a small pot.
I am new to growing veggies so this may be a total disaster but fun to try.
