Nothing comes close to this cos! Uniform, tender-crisp Romaine leaves with delicate white hearts and perfectly folded centers. Won’t brown when cut and contains considerably more nutrition than plain old iceberg varieties. Original bred for South Carolina, it’s one of the few lettuces that will tolerate heat. Wonderful in Caesar salads (or any salad), as a lettuce wrap, a dip-scooper or on your favorite sandwich. Disease-tolerant and bolt-resistant; also resists tip-burn.
