About these seeds
Romaine grows in tall, upright heads with crisp ribs and tender leaves — the lettuce of choice for Caesar salads and grilled lettuce wedges. Slightly more heat-tolerant than other lettuces but still prefers cool weather. Plant in early spring or fall, water consistently, harvest the whole head when it's full and dense.
