I don't want to sound unkind but how hard did you look for it? I did a quick search & found a source of seeds for this variety on my first try.

You can buy all sorts of diff tomato varieties at Tanager's Song Heirloom Seeds. I figured heirloom seed company would be the most likely place to have them but I didn't even specify heirloom seeds when I did the search. Scroll down the page & you'll find the seeds available at this site: http://www.tanagersongfarm.com/heirloom_seeds/tomato-paste.html

I don't know where in the US you live but Emery's Garden at 2829 164th St SW, Lynnwood, WA (phone: 425 743-4555) carries the plants. A phone call would check to see if they'll have them next year too.

Cook's Farm and Greenhouse, 1645 West 1600 N, Orem, UT (phone: 801 225-8271) also carries the plants.

This variety is also sold in the UK but I figure a US source would probably be better for you. Hope you enjoy them. If I'm right, they're not a hybrid so you should be able to save seeds for other years & maybe even share them around so more can enjoy them!

April 2011 Tanagers doesn't sell seeds anymore, I'm looking too.
