  • Augustus Lettuce

    Lettuce, Augustus (Organic)

    5 out of 5
    Lactuca sativa. Green. 60 days.

    A relatively tall romaine with smooth leaves and dense heads. Tolerant to lettuce mosaic virus and corky root rot, and resistant to downy mildew. This is another lettuce rescued from the USDA GRIN genebank, a former PVP variety that was dropped when the PVP expired (or maybe when Seminis bought Petoseed, the original developer of the variety). Legend has it the Roman Emperor Augustus was gravely ill and he was put on a diet of lettuce, which he credited with saving his life. True? Maybe we’ll never know.

  • Brown Goldring Lettuce

    Lettuce, Brown Goldring (Organic)

    Lactuca sativa. Bronze. 30 days baby; 55 full.

    Similar to Bunyards Matchless with more compact and open growth, slightly frilled leaf margins and dark green, crunchy leaves with bronze tips. Excellent sweet flavor. Very cold hardy, needing little protection to overwinter. Grows fairly well in the summer as well. A British heirloom originally by the name of “Goldring’s Bath Cos.” Won an award of merit from the Royal Horticultural Society in 1923. The Henry Doubleday Research Association found it to have three times the Vitamin C as summer lettuces. We sourced this variety from the Heritage Seed Library in England.

  • Bunyard's Matchless Lettuce

    Lettuce, Bunyards Matchless (Organic)

    Lactuca sativa. Bronze. 30 days baby; 60 full.

    Large, open heads are dark green with some bronze tint. Similar to George Richardson, Brown Goldring, and other Bath Cos types. Crunchy with distinctive nutty, sweet delicious flavor. This English heirloom is both cold and heat-tolerant. Scored higher overall than most other lettuces for both agronomic and eating qualities in the Heritage Seed Library’s 2008 Leafy Vegetable Project evaluation. Given to The Seed Ambassadors Project by the Heritage Seed Library in England.

  • Lettuce, Flashy Butter Gem

    Lettuce, Flashy Butter Gem (Organic)

    Lactuca sativa. Speckled. 30 days baby; 50 full.

    What we expected was a perfect, sweet Little Gem type lettuce with cool red speckles and more buttery texture. We got all of that and more! We waited a week after Little Gem size but they didn’t bolt, just got bigger and more colorful. Versatile and can be harvested as a mini-head or full size with no sacrifice on flavor or texture. A gourmet quality lettuce for salad mix and medium-sized heads to wow friends or market customers. Excellent planted spring, summer and fall. Not the hardiest in our 2010 winter trial but it lasted fairly well into the cold rainy season. Another excellent Frank Morton original, bred right here in Oregon.

  • george richardson lettuce

    Lettuce, George Richardson (Organic)

    Lactuca sativa. Bronze. 30 days baby; 65 full.

    This heritage lettuce from the United Kingdom is similar in flavor profile to other bronze romaines, which as a group are noticeably sweeter than other lettuce types. George Richardson has special bragging rights, though – in the 2009 evaluations done by Garden Organic / Heritage Seed Library, this family heirloom lettuce earned the title of the “best performing” heirloom. Loose heads are winter hardy and slow to bolt. Good field resistance to downy mildew. Given to the Seed Ambassadors Project by the Heritage Seed Library in England. It was donated to them by the late Mr. Richardson’s wife, who said it had been in the family for at least 60 years.

  • Greek Maroulli Cos Lettuce

    Lettuce, Greek Maroulli Cos (Organic)

    Lactuca sativa. Green Romaine. 30 days baby; 60 days full.

    A solid, medium-sized, bright green romaine lettuce. Forms crunchy leaves and tall heads. Many of the heads will form multiple hearts. We thought at first that we should select away from this trait, however we found it to be a fantastic trait for Romaine heart production and easy cutting salad mix. There are new patented lettuce varieties on the market that have similar traits to this and we believe that utility patents on natural traits that have existed for centuries to be outrageously corrupt. Here you will find some of the “Prior Art” of the plant world, to borrow some patent legalese. Originating in Greece, which is where many romaine/cos type lettuces were presumably introduced. Given to The Seed Ambassadors Project by the Heritage Seed Library in England.

  • Lettuce, Kalura

    Lettuce, Kalura (Organic)

    Lactuca sativa. Green Romaine. 30 days baby; 60 full.

    Very big, light green romaine heads. Good heat and cold tolerance with a crunchy sweet flavor. It still performs excellently and is a variety we’ve heard many farmers swear by. We swear by it too! This is our romaine of choice when growing for market, and our itinerant elk love it also. Once a popular commercial variety until it was dropped out of the catalogs.


  • Lettuce, Little Gem Pearl (Organic)

    Lettuce, Little Gem Pearl (Organic)

    Lactuca sativa. Mini Green Romaine. 50 days.

    A selection of Little Gem, this variety makes miniature heads of green romaine, and is possibly the best for sweet flavor. Because they are so compact, you can plant at twice the density of standard head lettuce, thus yielding more heads per bed foot. Also a great variety for container growing. A Royal Horticultural Society award winner, originally from England and said to be resistant to DM 1, 5 & 7.

  • Lettuce, Pandero

    Lettuce, Pandero (Organic)

    Lactuca sativa. Red Romaine. 30 days baby; 60 full.

    A deep red version of Winter Density. Very dense heads are slow to bolt, heat and cold tolerant. The red color darkens up early so it makes a very good salad mix variety. Can be harvested small for mini heads. Resistant to downy mildew. If you like Winter Density and you like red, you will like this. Originally from England.

  • Lettuce, Red Flamingo

    Lettuce, Red Flamingo (Organic)

    Lactuca sativa. Red Romaine. 30 days baby; 55 full.

    Open-headed frilly, pale red romaine with tender leaves that are perfect for salad mix. A unique lettuce variety from China that perfectly suits Pacific Northwest salad production. The flavor is very good and it was surprisingly cold tolerant in our 2010 winter lettuce trial. We harvested this for a mid-December salad mix and the quality was good after 3” of snow and temperatures down to 25°F, with only floating row cover for protection!

  • Romulus Lettuce

    Lettuce, Romulus (Organic)

    Lactuca sativa. Green Romaine. 30 days baby; 60 full.

    Big dark-green romaine with a crunchy delicious sweet flavor. The heads are slow to bolt and leaves form tightly without folding over on themselves to blanch a heart that is sweet. Heat tolerant and productive, we recommend this romaine especially for organic farm production, and it’s perfect for gardens, too. Released by Petoseed in 1991 before their infamous mergers. Formerly a PVP, the patent recently expired and this wonderful lettuce is now open source for us all to use freely. Originating from a cross between Valmaine and 24069, a University of Florida lettuce. Selected for tip burn and bolt resistance, large plants, non-cupping leaves and resistance to Lettuce Mosaic Virus (LMV).

  • Stoke Lettuce

    Lettuce, Stoke (Organic)

    Lactuca sativa. Mini Green Romaine. 50 days.

    Mini romaine, similar to Little Gem. Good for close plantings. Crunchy and dark green, very hardy and said to be capable of overwintering in the south of England (minimum temperatures of 10ºF) with no protection. This variety is originally from Stoke, located near Rochester, in Kent, England. It was grown by the Cheeseman family for 150 years, though likely dates from before 1840. We originally sourced this variety from the Heritage Seed Library in England.

  • Lettuce, Winter Density
    Out of Stock

    Lettuce, Winter Density (Organic)

    Lactuca sativa. Green Romaine. 30 days baby; 60 full.

    A serious lettuce classic. We do not carry many common varieties but when we do it is because we really love them. Halfway between a romaine and a butterhead, the crunchy buttery dense green heads are very cold and surprisingly heat tolerant. Very popular in England, its place of origin.
