For more than 125 years, gardeners have been growing Basil Lettuce Leaf types. Basil Salerno is no exception, simply the most productive variety, with large leaves on bushy, vigorous plants. The aroma is enticing, and the flavor is more sweet than spicy, a gentle mild bite that the entire family will love. Salerno’s 2 inches wide and 4 inches long leaves are serrated and crinkled. The leaves are very closely set on well-branched plants that are 18 to 24 inches tall. Salerno keeps producing, coming all season. Just pinch off the flower buds as they form, and it will keep growing more foliage.
