- So you want seed from the 'San Marzano' heirloom variety - *GROWN* in the San Marzano area.

In that case you best bet is to contact a local. From what I can determine most of the commercial growers have switched to hybrids that use the orginal 'San Marzano' as a parent - but are not themselves open-pollinated true heirloom variety traditional style 'San Marzano' tomatoes*** - which is one of the reasons the industry has put restrictions on who can use the name 'San Marzano' for their products.

If you would be satisfied with seeds from a strain that preserves the genetic identity of the 'San Marzano' - try one of the US or Canada heirloom seed companies - which have them for sale.


***why? when the 'San Marzano' is suppossed to be the pinnacle of taste etc ? Because the 'San Marzano is also an indeterminate type tomato - which reduces it's utility as a commercial tomato - so it has been crossbred to produce determinate plants (which ripen their crop all at one time) with fruit that stands up to processing better, etc. Hopefully not at a sacrifice of taste.
