Red Romaine Lettuce Seeds (Lactuca sativa var. longifolia) – 1000+ Non-GMO Heirloom Seeds for Planting, Tall Crisp Heads with Rich Red Tips, by Isla’s Garden Seeds, Gift Idea for Gardeners

Red Romaine Lettuce (Lactuca sativa var. longifolia) produces upright, elongated heads with sturdy ribs and textured leaves that blush deep red at the tips. The flavor is mild and slightly sweet, delivering satisfying crunch for salads, wraps, and sandwiches.

A cool-season standout, Red Romaine forms uniform heads that hold well in the garden, offering an extended harvest window in spring and fall. Plants reach 10–14 inches tall, with vibrant leaf color intensifying in cooler temperatures and full sun.

Harvest at the baby stage for tender mixes, or allow heads to mature for full-size hearts with classic romaine crunch. Dependable and versatile, it performs beautifully in beds, raised planters, and roomy containers.

With appealing color, crisp texture, and steady production, Red Romaine Lettuce is an essential choice for fresh, garden-grown greens throughout the cool seasons.

🌱Planting Instructions

Approx seeds per order 1000

Sow as soon as soil can be worked in spring, or in late summer for fall harvests. Choose a site with fertile, well-draining soil and full sun to light afternoon shade. For continuous salads, make small successions every 2–3 weeks.

Direct sow 1/8 inch deep in rows 12–18 inches apart. Keep the seedbed evenly moist for uniform germination (7–14 days). Thin seedlings to 10–12 inches for full heads; enjoy thinnings as baby greens.

Maintain steady moisture to keep leaves tender and mild. Harvest outer leaves regularly, or cut whole heads when firm and well-filled. Rinse and chill promptly after picking for peak crunch.
