Lunix is a stunning oak-leaf lettuce that brings rare elegance to any garden or market stand. Its lustrous, deep red leaves grow in an upright, symmetrical form and reach full harvest size in just 45 days, making it wonderfully fast. At 100 grams per head and only 3 to 4 inches tall with 8-inch spacing, it's perfectly scaled for succession planting and container growing. What truly sets Lunix apart is its exceptional nutritional density: a single 100-gram serving contains nearly a day's worth of vitamin A, more than virtually any other lettuce variety. As an heirloom that's rare in North America, it offers both superior flavor and the satisfaction of growing something genuinely uncommon.

Deep red, lustrous oak-leaf foliage with an unusually upright, symmetrical growth habit makes Lunix as beautiful on the plate as it is in the garden. The leaves are remarkably slow to bolt, extending the harvest window and rewarding patient gardeners with weeks of peak flavor. An antioxidant powerhouse, each 100-gram serving delivers nearly a full day's vitamin A requirement, making it one of the most nutritionally dense lettuces available. This combination of stunning appearance, reliability, and genuine nutritional punch explains why Lunix thrives equally well in market gardens, home beds, and hydroponic systems.
Lunix is grown primarily for fresh harvest and consumption as a salad green. Its tender, lustrous leaves are best enjoyed fresh, where their deep red color and delicate texture shine in composed salads or as a striking garnish. The variety's upright, symmetrical form also makes it visually appealing for market bunching or as an accent in restaurant-quality plating. Its compact 3 to 4-inch stature suits container and hydroponic cultivation, allowing year-round production in controlled environments.

Sow seeds indoors 4 to 6 weeks before your last spring frost in seed-starting mix kept at 60 to 70 degrees Fahrenheit. Lettuce seeds germinate best in cool conditions and need light to sprout; press seeds just barely into soil and keep moist. Transplant outdoors once seedlings develop two true leaves.
Harden off seedlings gradually over 7 to 10 days before moving them to the garden. Transplant when soil temperatures reach at least 60 degrees Fahrenheit. Set plants 8 inches apart in prepared beds with pH 6.0 to 7.0, in partial shade if temperatures exceed 80 degrees Fahrenheit. Water gently after transplanting to settle soil.
Direct sow seeds in early spring as soon as soil is workable, or in late summer for fall harvest. Sow seeds 1/4 inch deep and keep soil consistently moist until germination at 60 to 70 degrees Fahrenheit, typically within 7 to 10 days.
Begin harvesting outer leaves individually once the plant reaches 3 to 4 inches in height, typically 45 days after sowing. You can also harvest the entire head by cutting at soil level. The deep red color intensifies as the plant matures and remains vibrant throughout the cool season. For the most tender, flavorful leaves, harvest in early morning after dew dries. The upright growth habit makes cutting clean and easy, and the variety's slowness to bolt means you can extend harvest over several weeks rather than losing the crop to early flowering.

“Lunix represents a fascinating recovery of heirloom genetics. This oak-leaf type was exceptionally rare in North America before seed preservation efforts brought it back into circulation through specialty catalogs like Baker Creek Heirloom Seeds. The variety's deliberate selection for upright, symmetrical form and deep red coloration suggests a long history of careful cultivation, likely in European market gardens where such precise aesthetics were prized for fresh-market appeal. Its documented suitability for both traditional field production and modern hydroponic cultivation hints at a lineage refined across generations to meet diverse growing conditions.”
