Lettuce ‘Grosse Blonde Paresseuse’ is a historic French butterhead (Boston‑type) lettuce, first cited in Les Plantes Potagères by Vilmorin‑Andrieux in the late 19th century—around 1891 in France and documented in English catalogs as early as 1869. Its whimsical name—literally “big lazy blonde”—refers both to its pale blond-green head and its reputation for being slow to bolt (“lazy”) even in warm weather. The summer lettuce ‘Grosse Blonde Paresseuse’ produces a voluminous butterhead head with a round, slightly flattened shape, and pale to blond-green foliage throughout. Inner leaves remain creamy-green with a tender yellow heart. The leaves are very tender, mildly sweet and crisp, lightly blistered or wavy in appearance. Bitterness is low thanks to its slow bolting trait.
