Lettuce 'Muir'
Lactuca sativa
If you've ever had trouble growing lettuce because of the heat, try Muir! It is the most heat-tolerant lettuce that we grow with excellent flavor and crisp texture. Dense heads can be harvested as small or left to bulk up. I've been growing Muir since 2016 and it never disappoints. Seed is certified organic.
Sexier vegetables might steal the spotlight, but greens are where it’s at! Why settle for store-bought lettuce when you can have fresh, organic, and nutritious salads right from your backyard? The secret to keeping homegrown lettuce refreshingly crisp? Harvest first thing in the morning and immediately submerge in cool water.

How to Grow
Sow indoors 3–4 weeks before planting out. Keep trays cooled below 75°F during germination. Lettuce is a cold-hardy crop that prefers cool temperatures. Young plants properly hardened at least 3–5 days before planting can survive temperatures as low as 20°F. Can be direct sown in soils as cool as 40°F.
Harvest & Storage
Once established, harvest leaves before flowering begins. Leaves can be harvested 3–4 times per year, cut at ground level. Leaves may be used fresh or dried. To dry, cut bundles into 1/4–1/2" lengths. Dry on a screen surfaced out of direct sunlight in an area with good ventilation. Stir periodically.
