What is Romaine lettuce known for?
Romaine (Cos) lettuce forms tall, upright heads of sturdy, crisp leaves with a sweet, mild flavor and a crunchy rib. It is the classic lettuce for Caesar salads and holds up well to dressing.
When should I plant Romaine lettuce?
Sow in early spring 2–4 weeks before the last frost and again in late summer for a fall crop. Romaine grows best in cool weather and is fairly heat-tolerant for a heading lettuce.
How long does Romaine take to mature?
Romaine forms full heads in about 65–75 days, with baby leaves harvestable earlier. Steady moisture keeps the ribs sweet and crisp.
How far apart should Romaine be spaced?
Thin or transplant to 8–10 inches apart in rows 12–18 inches apart so the upright heads can grow tall and full.
How do I harvest Romaine lettuce?
Cut the whole head at the base once it is tall and firm, or pick outer leaves as needed. Harvest before hot weather to avoid bitterness and bolting.
Are Romaine lettuce seeds heirloom and non-GMO?
Yes, this Romaine is open-pollinated and non-GMO. The packet contains about 1,250 seeds.
Is romaine the same as cos lettuce?
Yes. Cos is another name for romaine, referring to the same tall, upright type.
Does romaine handle heat well?
Better than most lettuces, though it still grows best in cool weather. Steady water helps prevent bitterness and bolting.
