First introduced by Cornell University, Buttercrunch debuted as the \u003cstrong\u003e1963 All-America Selections (AAS) vegetable winner\u003c\/strong\u003e for its exceptional tolerance to stress, poor soils, and bolting from summer heat. Also recommended by Utah State University as a top performing lettuce for home gardens. Compact, loose heads with smooth, thick, juicy leaves deliver a mildly sweet, buttery flavor that earns its name. Notably slow to bolt — giving you a longer harvest window than most lettuce. Harvest as baby greens from 21–30 days, pick outer leaves for continuous cut-and-come-again harvest, or wait for a full tight head at 60–70 days. 65 days.\u003c\/p\u003e\u003ch3\u003eWhy Grow Buttercrunch?\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1963 AAS Award Winner\u003c\/strong\u003e — introduced by Cornell University, proven for 60+ years\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSU-recommended variety\u003c\/strong\u003e — top-rated performance for home gardens\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMost popular butterhead type\u003c\/strong\u003e — a classic that earns its place every season\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMildly sweet, buttery flavor\u003c\/strong\u003e — thick, juicy, smooth, and tender leaves\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlow to bolt\u003c\/strong\u003e — extended harvest window compared to most lettuce varieties\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriple harvest option\u003c\/strong\u003e — baby greens, cut-and-come-again outer leaves, or full head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerates stress and poor soils\u003c\/strong\u003e — reliable in a wide range of garden conditions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen-pollinated heirloom\u003c\/strong\u003e — save seed year after year\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHarvesting Options\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBaby greens:\u003c\/strong\u003e Begin harvesting tender young leaves at 21–30 days when plants are 3–4 inches tall — mild, delicate, and excellent in salads. \u003cstrong\u003eCut-and-come-again:\u003c\/strong\u003e Snip outer leaves as needed at any stage — plants will regrow vigorously from the center.

Use whole leaves as lettuce wraps for Asian-inspired fillings. Layer in sandwiches and burgers where the buttery texture shines. Tear into a classic garden salad with vinaigrette.

Sow seeds 1 inch apart in rows 12–18 inches apart; thin to 6 inches as plants develop — crowding causes bitterness.

In hot climates, provide afternoon shade or mist foliage during peak heat to delay bolting.
