If you have seen the Dwarf Project through Victory Seeds, that project involves hundreds of varieties being developed by hundreds of growers mostly who visit the tomato forum site Tomatoville. Craig L. in the northern hemisphere and Patrina in the southern hemisphere are the moderators. It has been several years of trial and retrial to get dwarf sized plants with full sized fruit that tastes good. All varieties developed so far have been indeterminate. I have personally been involved with at least twelve of the new releases of dwarfs in the Project at some stage.
As with all tomatoes, they thrive when being planted directly in the soil but will also do well in containers. My opinion is that even the dwarfs require at least a 5 gallon pot. As a side note, the best salsa and sauce we have ever made came not from traditional "sauce and salsa" style tomatoes but from regular heirloom/OP varieties. So much more flavor.
Also selling the International Dwarf Project tomatoes besides Victory Seeds are The Sample Seed Shop, Tatiana's Tomatobase and Sand Hill Preservation. Victory has a very good presentation of those varieties released to date with more coming My personal favorites are Tasmanian Chocolate and Wild Fred.
