I grew San Marzanos last year for the first time -- they were very productive, but I agree with Rita that they were very solid, much more suited to making sauce and canning than just eating fresh IMO. My plants were also quite tall (over 5 feet), so I wouldn't say they are the best type for growing in containers (although I'm sure plenty of people do so). Definitely give them some good (tall) support.
Welcome to All Things Plants, Amber -- I hope you'll join us over on the vegetables and fruits forum and let us know how the SMs do for you!
