Adaptive Seeds Cool Season Lettuce Mix (Organic)

Lactuca sativa. 28 days.

Seasonal lettuce mixes are a great way to achieve culinary and growing success. This mix is best sown in spring (March-April) and autumn (September-October), and includes varieties that have shown excellence in our spring and fall lettuce trials. All varieties will germinate in diverse soil conditions and are cool weather tolerant. With a diverse mix of flavors, colors, and textures, the Adaptive Seeds Cool Season Lettuce Mix is sure to delight the palate of everyone from the garden novice to the lettuce aficionado. Includes easy to grow romaine, butterhead, loose leaf, and oak leaf types. Most suitable for cut-and-come-again cultivation, but could also be sown for head lettuce. This mix is most comparable to what we formerly called Adaptive Seeds Lettuce Mix.

Sow indoors in flats with good potting soil year-round. Transplant into the garden 3-4 weeks after sprouting at 3″ spacing for leaf, 12″ for heads. Alternatively, direct sow March through September. In our area, lettuce can go through winter if protected. Succession sow for continual harvest.

Seed Saving

Collect seeds when flowers are downy like dandelions. Cut seed heads and place upside down in a bag to dry for a few days. Knock seed heads against side of bucket or tote, rub downy fluff off seeds. Winnow and screen to clean.

    Where did you grow this variety? Washington

    Love it. Grown this the last two years. This summer is distinctly cool and it is particularly happy, as you might expect given it’s name.
