Often called giant leaf basil, this variety produces some of the largest leaves of any sweet basil, making it a favourite for pesto, salads, sandwiches, wraps, and fresh summer cooking.
The large leaves resemble loose lettuce leaves, which is exactly how this variety earned its name. A mature lettuce leaf basil plant can produce abundant foliage throughout the growing season, providing continuous harvests for home gardeners and culinary enthusiasts alike.
If you're looking for premium lettuce leaf basil seeds, this variety offers excellent flavour, vigorous growth, and impressive yields in both garden beds and containers.

Basil is widely studied for its aromatic oils, antioxidants, and culinary value. Like other sweet basil varieties, lettuce leaf basil contains compounds such as eugenol and linalool that contribute to its characteristic fragrance and flavour.
What Is Lettuce Leaf Basil?
Lettuce leaf basil is a specialty basil variety bred for its exceptionally large leaves. While standard sweet basil typically produces smaller foliage, lettuce leaf basil can develop leaves measuring up to 4–6 inches across under ideal growing conditions.
The leaves are bright green, heavily textured, and slightly puckered, giving them a distinctive appearance that resembles loose-leaf lettuce. This combination of size and flavour makes lettuce leaf basil one of the most productive basil varieties for home gardens.
Gardeners searching for giant leaf basil are often looking for this exact variety.
How to Grow Lettuce Leaf Basil From Seed
Lettuce leaf basil seeds can be started indoors 4–8 weeks before your last expected frost date or direct sown outdoors once soil temperatures are consistently warm.
Sow seeds approximately ½ inch deep in fertile, well-draining soil and keep the growing medium evenly moist until germination occurs. Seeds typically sprout within 5–10 days under warm conditions.
Basil thrives in full sun and warm temperatures. Because it is not frost tolerant, wait until all danger of frost has passed before transplanting seedlings outdoors.
This variety grows equally well in garden beds, raised beds, and containers. For more small-space growing options, visit our Container Garden Collection.
How to Harvest Lettuce Leaf Basil
Regular harvesting is the secret to a productive lettuce leaf basil plant.
Once plants have developed several sets of leaves, begin harvesting by pinching stems just above a leaf node. This encourages branching, resulting in bushier plants and significantly more leaf production.
Avoid harvesting more than one-third of the plant at a time. Frequent harvesting prevents flowering, extends production, and improves overall leaf quality.
The large leaves make harvesting especially efficient because a single leaf often provides enough basil for an entire recipe.
Lettuce Leaf Basil Growing Stages
| Stage | What to Expect |
|---|---|
| Germination | Seeds sprout within 5–10 days |
| Seedling Stage | Small aromatic leaves begin forming |
| Vegetative Growth | Rapid stem and leaf production |
| Large Leaf Formation | Characteristic oversized leaves develop |
| Harvest Stage | Continuous harvesting encourages branching |
| Flowering Stage | Plants begin producing flower spikes if not harvested regularly |
Fertilizer for Lettuce Leaf Basil
Because basil is grown primarily for foliage production, it benefits from fertile soil rich in organic matter. Incorporate compost before planting and maintain consistent watering throughout the season.
A balanced organic fertilizer can support vigorous growth, but excessive fertilization may reduce flavour intensity. For more information, read our Organic Fertilizer Guide.
