Deeply Rooted
I didn't realize there were several strains of San Marzano. That is really good to know!!There are several versions of San Marzano in circulation. I grew the original Roma-type one in the 80's; it was larger & more productive than Roma (and did surprisingly well in part shade) but IMO just OK taste-wise. San Marzano Nano is an indeterminate tomato with 2-3 ounce sausage-shaped tomatoes; it had a great yield, but I didn't (and still don't) have the equipment to process them efficiently. San Marzano Redorta is indeterminate, and has elongated 6-8 ounce tomatoes with few seeds & really great flavor. SMR is the only one I still grow. It is late, but since it tends to ripen about the same time as my heirloom peppers, it is well suited for making canned salsa.
