History
Giant Caesar Lettuce is a robust heirloom romaine variety with a name that says it all — bred for the bold, crisp heads that make the perfect Caesar salad. A selection within the storied romaine family, Giant Caesar was developed for its exceptional size, upright habit, and thick, crunchy leaves that hold up beautifully to dressings and toppings. Romaine lettuce itself has a history stretching back thousands of years, with origins traced to the Mediterranean and ancient Egypt. Giant Caesar carries that heritage forward with the added advantage of impressive head size and outstanding garden performance. Open-pollinated and non-GMO, every seed carries the same reliable genetics that gardeners have saved and replanted for generations.

Flavor Profile
Giant Caesar Lettuce delivers the classic romaine flavor — crisp, mildly sweet, and slightly bitter in the best possible way. The thick, crunchy leaves have a satisfying texture that holds up to bold dressings without wilting, making them the gold standard for Caesar salads. The pale interior leaves are the most tender and flavorful, with a buttery sweetness that contrasts beautifully with the more robust outer leaves. One of the most flavorful and versatile lettuces you can grow.
Growth Type & Harvest Yields
Giant Caesar forms a large, upright head over 70–80 days. You can harvest outer leaves continuously as the head develops, or wait for the full head to mature and harvest all at once. Its large size means a single head can anchor an entire salad. In cool weather it holds in the garden for an extended period without bolting, giving you a generous harvest window. Expect impressive, substantial heads that live up to the Giant Caesar name.
Disease Resistance
- Good tolerance to tip burn in cool, well-ventilated growing conditions
- Performs best in cool weather — heat accelerates bolting
- Upright habit promotes good air circulation, reducing fungal disease pressure
- Tip: Succession sow every 2–3 weeks for a continuous harvest through the cool season
Growing Tips & Planting Dimensions
- Spacing: 10–12 inches between plants, rows 18 inches apart
- Sow depth: ⅛ inch deep — lettuce needs light to germinate; do not cover deeply
- Germination: 7–14 days at soil temps of 40–75°F (optimal 60–70°F)
- Full sun to partial shade — partial shade extends the harvest in warmer weather
- Prefers fertile, well-drained soil with consistent moisture
- Keep soil consistently moist during germination — lettuce seed is sensitive to drying out
- Mulch around plants to retain moisture and keep soil cool
When to Plant
Direct sow 4–6 weeks before your last frost date for a spring crop, or start indoors 4–6 weeks before transplanting. For a fall crop, direct sow 8–10 weeks before your first fall frost. Lettuce thrives in cool weather and will bolt in summer heat — time plantings for spring and fall harvests. Find your frost dates and hardiness zone at the USDA Plant Hardiness Zone Map.
Companion Plants & Mutual Benefits
-
Radishes — fast-maturing companion that loosens soil and deters leaf miners; harvest before lettuce fills in
-
Carrots — deep roots loosen soil without competing for surface nutrients
-
Chives & Garlic — repel aphids and other common lettuce pests
-
Strawberries — lettuce acts as a living mulch beneath strawberry plants
-
Avoid planting near: fennel — allelopathic and inhibits growth of most vegetables including lettuce
