“Buttercrunch” is a type of butterhead lettuce that is slightly more tolerant of heat and, thus, very popular in southeast Texas. They are sought after for their “buttery” flavor and velvety texture. The small, loosely formed heads yield leaves that are at once delicate and yet strong enough to roll into lettuce wraps. Buttercrunch lettuce has soft, green, slightly curled leaves wrapped around a loose inner head of blanched, sweet-flavored, interior leaves. It stays mild long after other butterheads become bitter. Provide full sun to partial shade, keeping the soil consistently moist but not waterlogged. Buttercrunch thrives in moderate temperatures, so planting during Houston's cooler seasons allows it to grow into a tender, sweet head.
