San Marzano is both a denomination of origin and a variety.
Like GB said, the reason the real canned SM tomatoes grown in the San Marzano region of Italy are so special is because of the soil they grow in. Sandy, volcanic soil from Mt Vezuvius (sp?). Like grapes (or reallyanything you grow), soil has a great deal to do with the flavor and texture you get from tomatoes.
You can grow them from seeds anywhere, but they don'e have the same taste as the real deal from Italy.
I have started to grow them every year in my garden and there's really no comparison beween mine and a high quality canned SM.
Mine are getting planted this weekend.
