  • Lettuce, Cerise Oak Leaf (Organic)

    Lettuce, Cerise Oak Leaf (Organic)

    $3.50$6.50
    Lactuca sativa. Red Oak Leaf. 30 days baby; 55 full.

    An excellent red oak leaf and great for salad mix. Vigorous and slow to bolt with good sweet flavor, especially for a red lettuce. Fairly resistant to downy mildew. Dark-red pigmented anthocyanins fight the diseases of cold wet weather and provide good color contrast in mixes. Cerise means “cherry” in French. An English commercial variety that we found in Ireland with Madeline McKeever of Brown Envelope Seeds.


  • Lettuce, Florence (Organic)

    Lettuce, Florence (Organic)

    $3.50
    Lactuca sativa. Green Oak Leaf. 30 days baby; 55 full.

    Bright green oak lettuce has the crisp texture of a romaine. The surprising sweet crunch made us think about dividing the oak leaf lettuce category into butter oaks and crisp oaks, but that is another conversation. The dense heads resist bolting in the field, instead they just keep getting bigger. A fabulous lettuce for full heads, cut-and-come-again style or salad mixes. We are always surprised about how many great and unique lettuces there are out there; Florence is the most impressive of our USDA GRIN accessions grown in 2013.


  • fristina lettuce

    Lettuce, Fristina (Organic)

    $3.50$6.50
    Lactuca sativa. Green Oak Leaf. 25 days baby; 60 full.

    Produces large, dense heads of deeply serrated oak leaves great for cut-and-come-again salads. This lettuce is so deeply cut it almost looks like a frisée endive. When the heads are medium sized they can be grabbed and cut about an inch above the ground, the handful of lettuce will then fall apart into a perfect bowl of salad. Crunchy sweet midribs make great salad and the heads hold up well in the summer heat. Showed good field resistance to downy mildew when the disease was attacking many other varieties on our farm.


  • Lettuce, Galisse (Organic)

    Lettuce, Galisse (Organic)

    $3.50$12.50
    Lactuca sativa. Green Oak Leaf. 30 days baby; 55 full.

    Very reliable, compact green oak leaf, perfect for heads or salad mix. This was a commercial standard until recently, when it was replaced by patented varieties that are almost identical. If you want a solid, open-source green oak leaf, this is for you. Not only is it just plain beautiful, it is heat tolerant, bolt resistant and it holds its excellent mild flavor for weeks past other varieties. Very resistant to most strains of downy mildew.


  • Garnet Red Oak Lettuce

    Lettuce, Garnet Red Oak (Organic)

    $3.50
    Lactuca sativa. Red Oak Leaf. 30 days baby; 55 full.

    A classic red oak leaf with good deep red color and a unique, slightly upturned leaf architecture. Good color in low light conditions and fairly disease resistant. Great in most weather conditions. We have had small plants of this variety survive overwinter outside with no protection. A popular Northwest variety that has been floating around here for a long time, although it is strangely difficult to find sometimes.


  • Morgana Lettuce

    Lettuce, Morgana (Organic)

    $3.50$12.50
    Lactuca sativa. Red Oak Leaf. 30 days baby; 55 full.

    Red and green semi-oak-leaf heads have some arrowhead/canary tongue shape. The sweet juicy flavor, cold and heat tolerance, as well as the large and vigorous plants all come together to make this one a favorite. Great for salad mix and for unique full-sized heads. We sourced Morgana originally from Washington seed saver Alice Swan in 2010, who got it from lettuce collector and Seed Savers Exchange Curator Mary Schultz of Monroe, Washington. This lettuce is very popular with seed savers in the Pacific Northwest but has rarely been commercially available.


  • Lettuce, Smile (Organic)

    Lettuce, Smile (Organic)

    $3.50$12.50
    Lactuca sativa. Green Oak Leaf. 30 days baby; 55 full.

    Great for salad mix production. Heads up nicely for the perfect sized salad at home. The bright green color and sweet flavor coupled with the soft delicious texture make it great. Similar in appearance to Galisse but with the ability to attain a much bigger head. If your goal is to grow a ton of salad this is the right variety for you. Seems to be fairly heat tolerant and definitely slow to bolt. Good choice for cut-and-come-again salad growing. Said to be popular in Europe for outdoor field or greenhouse production, and to be bottom rot resistant. For us, Smile was very resistant to tip burn and mildew; plenty to smile about!
