Lettuce is the most commonly grown salad green in Australian home gardens. Available in four main types: crisphead (iceberg), cos/romaine, butterhead, and loose-leaf. It is a cool-season crop that bolts rapidly in heat, making variety selection and planting timing critical. Fast-growing (4-8 weeks to harvest) and adaptable to containers, garden beds, and even part shade.
