  • Baja Lettuce

    Lettuce, Baja (Organic)

    Lactuca sativa. Green Butterhead. 55 days.

    Small, dark green butterhead lettuce that is good for summer production because it is more heat resistant than most. A lot like the larger market farm standard Optima with nice thick leaves that hold up well in the market booth but with a darker green color. Another lettuce from the USDA GRIN vault. Not sure why this modern variety was not released by its developer. We are happy to release it to the public.

  • Lettuce, Bríwerí (Organic)

    Lettuce, Bríwerí (Organic)


    Lactuca sativa. Green Butterhead. 50 days.

    Light-green butterhead, bred for greenhouse & cold frame forcing in winter & spring. Quick to size up in cold conditions, we have frequently planted it spring & fall, outdoors under row cover with great results. Excellent variety we sourced from the German biodynamic seed company, Bingenheimer Saatgut. They recommend sowing in late November in an unheated hoophouse for April harvest. Resistant to DM races 12, 17, 18, 22, 24, 25. Bred by Richard Specht with support from Kultursaat, a German Foundation dedicated to advancing open-pollinated varieties.

  • Lettuce, Brune Percherone (Organic)

    Lettuce, Brune Percherone (Organic)

    Lactuca sativa. Red blushed Butterhead. 60 days.

    An apple green butterhead tinged with a red-pink blush. Early, big, heavy heads grow well in difficult conditions & are heat resistant. An old variety known in Europe since around 1907. Most recently preserved from extinction by the seed saving groups Kokopelli in France, & Pro Specie Rara in Switzerland. We found this variety with Pro Specie Rara during our 2007 Seed Ambassadors trip.

  • Lettuce, Cindy (Organic)

    Lettuce, Cindy (Organic)


    Lactuca sativa. Green Butterhead. 55 days.

    Large, light-green butterhead that produces high quality heads with a delicate buttery texture & sweet nutty taste. Bred for spring or summer production with good bolt resistance. This excellent variety outperformed every other lettuce we planted in our 2009 fall trial of 20 varieties. European commercial variety dropped from the EU Common Catalog. Saved from extinction by Christina Henatsch, a biodynamic plant breeder in Germany, who gave it to us on our 2007 Seed Ambassadors trip.

  • Lettuce, Focus (Organic)

    Lettuce, Focus (Organic)


    Lactuca sativa. Green Butterhead. 55 days.

    Focus is a solid green butterhead with slightly thicker than average leaves which deliciously do not melt in your mouth like so many other butterheads, but rather have a slight crunch. Still pleasingly tender, just not overly so. Leaves are sweet, & hold up well for market. More substantial leaves also make it more heat resistant & good for summer production. Another gem of a lettuce rescued by USDA GRIN. Focus was bred in the mid-1990’s by a large seed company who applied for a PVP but dropped the application a few years later. As far as we know it never was available commercially. We sourced it from GRIN a few years back & are happy to make it available, as we think it is a good lettuce with a lot of potential.

  • Hansen Red Batavian Lettuce

    Lettuce, Hanson Red (Organic)

    Lactuca sativa. Green & Red Crisphead. 65 days.

    This Batavian type is one of our best lettuces for summer production. Dense heads with dark green thick leaves & red tips. Delightfully crunchy & resists tip-burn. Very slow to bolt. Not suited to winter production. This lettuce comes to us from a Seed Savers Exchange member & is different from the commercial standard of the early 1900s called Hanson, which does not have any red coloration. We don’t think iceberg lettuce is necessary when there are Batavians around.

  • Hungarian Winter Pink Lettuce

    Lettuce, Hungarian Winter Pink (Organic)


    Lactuca sativa. Red Butterhead. 60 days.

    Winter hardy, light-red butterhead originating in Hungary. The 12” green heads are splashed with red-pink. Very tender & delicious. Fairly quick to bolt in the heat but perfect for spring & fall rotations. When growing for market, we liked to plant a late rotation in September to produce dense, 6” mini-heads for harvest in December/ January. We then harvested whole heads & broke them up into our salad mix (we did this years before “Salanova” came out). It was a quick way to add color & bulk up salad mix in the dead of winter. Interior leaves maintain quality down to 20°F. It came to us via the Occidental Arts & Ecology Center (OAEC) in California.

  • Leda Lettuce

    Lettuce, Leda (Organic)

    Lactuca sativa. Green Crisphead. 60 days.

    Crisphead type that forms large, round, dense heads. Leaves are very light green with a good sweet flavor. A bit more tender than standard crispheads & definitely more tender than the icebergs. Very slow bolting. Originally from a Slovenian seed company, this lettuce comes to us by way of Tatiana’s TomatoBase, a great seed source in British Columbia that is more than just tomatoes.

  • Lettuce, Mikola (Organic)

    Lettuce, Mikola (Organic)

    Lactuca sativa. Red Butterhead. 50 days.

    A medium-sized, dark-red butterhead that stood out as one of our best varieties of 2010. Easy to grow & tolerant of summer heat. Great color, overall appearance & succulent texture. A reliable variety for gardens & market farms, it was a commercial standard for organic farms a decade ago but then nearly disappeared. It is sad when the big seed companies drop good varieties & we love to keep them available. Thanks again to Turtle Tree Seed for turning us on to this variety.

  • Lettuce, Northern Queen (Organic)

    Lettuce, Northern Queen (Organic)

    Lactuca sativa. Green Butterhead. 50 days.

    Beautiful light-green butterhead that was a popular in the 1950s on English farms & in gardens. Quick to produce a medium-sized head. Cold & damp weather tolerant & resists bolting until the summer gets hot. Originally sold by Finney’s of Northumberland, England, before 1950. Given to The Seed Ambassadors Project by the Heritage Seed Library, England during our visit there in 2007.

  • Lettuce, Red Vogue

    Lettuce, Red Vogue (Organic)


    Lactuca sativa. Red Butterhead. 48 days.

    This showy lettuce is like having Madonna in your garden. An early red butterhead with great color & size. A former favorite of commercial growers & thanks to USDA GRIN it was saved from extinction. We chose it in our trials because it’s just plain great for farmers & gardeners looking for a quick reliable red butterhead. Red Vogue was released by Sakata Seed in the early 1990s as a “patented variety” through the PVP system but now the PVP has expired. These days companies prefer to use utility patents which are much more monopolistic, even restricting research & plant breeding.

  • Lettuce, Salade de Russie

    Lettuce, Salade de Russie (Organic)

    Lactuca sativa. Speckled Crisphead. 60 days.

    A large crisphead Batavian type lettuce. Olive green with a nice bronze blush & covered in beautiful red speckles. In passing it could be mistaken for a Castelfranco chicory but with close inspection it is all lettuce. Sweet crunchy flavor even in the heat of summer. Slow to bolt. Seems to be fairly cold tolerant as well. A really good lettuce with a funny name suggesting it is originally from Russia. We have tracked its travels from Terre de Semences, also known as Association Kokopelli, in France, to author William Woys Weaver, to the Seed Savers Exchange Yearbook.

  • Sangria Lettuce

    Lettuce, Sangria (Organic)

    Lactuca sativa. Red Butterhead. 55 days.

    A really great, medium-sized red butterhead variety. Was once popular with market growers but disappeared after the PVP expired. Smooth leaves are red tipped with green interiors. Bred for resistance to lettuce mosaic virus, sclerotinia & downy mildew, Sangria is also heat tolerant, resists tipburn & holds longer in the field without bolting. Bred from Mereville des Quatre Saisons by Vilmorn & released in 1989, the PVP expired in 2009 making this variety available to the public domain. We fell in love with this variety when we were farm apprentices at Horton Road Organics in 2004, & sourced our seed from the USDA GRIN gene bank.

  • Slogun Lettuce

    Lettuce, Slogun (Organic)

    Lactuca sativa. Green & Red Crisphead. 60-90 days.

    Heads are green with bronze tips. Upright heads size up quickly but then can sit in the field for weeks before bolting. Great for folks that like to have lettuce in the garden but don’t like to eat it all at once. Slogun will wait for you to decide to eat a BLT & it will wait for the tomatoes to come on too. We eat a lot of BLT’s when Slogun is around. The slowest bolting lettuce we have successfully produced seed for. An old Tim Peters variety that comes to us via Turtle Tree Seeds.

  • Lettuce, Unicum (Organic)
    Out of Stock

    Lettuce, Unicum (Organic)


    Lactuca sativa. Speckled Crisphead. 55 days.

    Unlike the bitter Hungarian alcohol with the same name, Unicum lettuce will not grow hair on your chest. The name, which means “specialty” in German, is definitely appropriate for this wonderful lettuce. Large crisp green heads are slow to bolt & heat resistant. Leaves are bright green & some red speckles. Great flavor & texture. Seed stock came to us originally via Occidental Arts & Ecology Center in Northern California.

    Will be back in 2017.
