Organic Buttercrunch Lettuce Seeds - Lactuca sativa

Organic Non-GMO Open Pollinated Butttercunch Lettuce Seeds

A beloved heirloom variety and All-American Selections winner since 1963, Buttercrunch lettuce is renowned for its exceptional heat resistance, delayed bolting, and natural immunity to mosaic virus—qualities that make it a reliable choice for both home and market gardens alike. This time-tested variety thrives in warmer climates where other lettuces may struggle, offering a consistent, bountiful harvest.

As a butterhead-type lettuce, Buttercrunch forms compact rosettes of thick, juicy leaves that are soft and tender, with a mild, sweet, and buttery flavor. Its delicate texture makes it the perfect foundation for fresh, vibrant salads, adding a creamy contrast to the crunch of more robust varieties like Romaine.

Ideal for growers seeking a dependable, flavorful lettuce that performs well in diverse conditions, Buttercrunch brings both beauty and flavor to your garden or table. Additionally, its tolerance to heat makes it a standout during the hotter summer months, allowing for extended harvests and fresh greens all season long.

Gardener Tips

Keep seeds moist while germinating. Will grow into the space that is provided, give space if possible. Add compost to soil.

Each packet of seeds contains a generous amount of seeds, so you can plant in succession!.  For a continuous harvest, make successive plantings every 10-14 days. Read our blog post on How to Always Have Greens Coming out of the Garden!

Water only in the morning, do not spray leaves.

When starting seeds indoors, it is key to harden off your seedlings. Hardening off is a process that requires taking seedlings outside during the day, for a period of time, before they are transplanted into the ground. This acclimates your seedlings to the outside world, meaning the elements like the wind and sun. We do it for several weeks to a month as this strengthens their stems and overall plant structure. 

• Start for a short period of time initially, then graduate to more time each day
• One week minimum is recommended
• Bring them inside in the early evening and overnight
• Keep an eye on them and keep them moist. Make sure they have not blown over. 

Harvest Tips

Harvesting lettuce in the early morning or evening is ideal.   The plant is cool and hydrated. Midday heat causes the leaves to wilt, lose moisture, and turn bitter, which can affect both taste and texture. By harvesting during the cooler parts of the day, you preserve the lettuce’s crispness, flavor, and shelf life.
