50 Seeds Muir Lettuce Lactuca sativa Crisp Heat Tolerant Garden Salad Greens

Muir lettuce is a vigorous open-pollinated romaine type prized for its upright, self-blanching heads and sweet, crisp leaves with a mild flavor. It performs well in warm weather where other lettuces bolt quickly, making it a dependable choice for home gardeners who want steady harvests of flavorful greens across the season.

Enjoy Muir lettuce fresh in salads, sandwiches, wraps, and as a garnish, or use outer leaves young in mesclun mixes. It grows upright for easy picking, matures in roughly 50 to 60 days, and holds quality in the garden longer than many standard romaines. Succession sow every two to three weeks for a continuous supply.
