Buttercrunch lettuce is a premium quality European Bibb lettuce with delicate flavor. The tender, compact 5�-6� heads have slightly crumpled green leaves with a creamy yellow core. Its buttery, tender texture makes it perfect for salads, giving them a gourmet touch. A vigorous grower, it loves moist but not soggy soil and is easy to grow, even in containers! Buttercrunch is also bolt resistant and will withstand a little more heat than many other lettuce varieties. This high performance variety has been a standard for Butterhead lettuces for many years. It was an All America Selections Winner in 1963. When to plant outside: Early spring, 3 to 4 weeks before the average last frost, and successive plantings thereafter every 3 weeks until 2 weeks before the first fall frost. In USDA zone 8 or warmer, it can also be sown in fall for winter harvest.
