Buttercrunch' is a vigorous grower with a creamy yellow interior, buttery flavor and melt-in-your-mouth texture, pleasing palates since 1963. Small heads are perfect for a single-serve salad. The compact size makes it a good container variety, and it's also attractive in the flower-garden border. All-America Selections Winner.
