San Marzanos are special because of where they are grown in Italy in volcanic soil. So when buying canned tomatoes, yes it matters. When growing in other areas, it really does not. Instead look at what plum variety grows well in your area.
I found some info for you:
If you want to grow a paste tomato for sauces or canning, the best varieties for Kentucky include Plumb Dandy, Roma VP and Plum Crimson, which mature in 76 to 80 days.
I want to grow some of these to make some sauces. Are these widely considered to be the best for sauce making? Also should I try to find plants or start from seeds? I'm thinking it's too late in the year to start from seeds now.
I'd have to agree with the other poster who said to pass on the San Marzanos. I grew them this year and they were nothing special. not even as juicy as a roma you might buy at the local produce market.
they seemed to all be kind of dry on the inside and the flavor, well I'll let you know when I find it. it made the Sungolds I was growing right next to them taste like absolute tomato heaven in a mouthful.
not sure why these Marzanos are so hyped. I actually found a lot of these so-called "tastier" heirloom tomatoes that I grew this year to be nothing special.
taste it before you grew it, tomatoes are much fussier than peppers (I find) so you'll be putting some effort into growing these.
thumbs down on the San Marzanos.
sounds like the local plum shaped commercial tomatoes available here.
"Fruit has the gold color and flavor of the Sungold, the meatiness of the Amish Paste and delicious sweet/tart tomato flavors that will have you want this as a favorite tomato in your garden."
Quick question about the canned San Marzanos, are they really THAT much better than the rest? Reason I ask is, they are generally 5X the price here.
if you meant the canned san marzanos from italy then, afaik yes. =D
