Johnny's reputation for exclusive, tried-and-tested varieties shines through with this mix. The short 28-day harvest window means you're picking fresh leaves less than a month after planting, while the frost tolerance extends your season on both ends, letting you start with your earliest soil work and keep harvesting well into cool fall weather. Its open-pollinated genetics mean you can save seeds from your best plants, building a strain that adapts to your own garden's rhythms.
As a gourmet lettuce mix, this blend is designed for fresh salads where the combination of leaf textures and flavors creates complexity in every bite. The quick maturity and tender leaves suit fresh eating straight from the garden, and the mix format means you get multiple leaf types in a single planting, eliminating the need to grow several varieties separately if you want variety on your plate.

Start seeds indoors in cool conditions, keeping germination temperature between 60 and 70°F for best results. Aim to start seeds about 4 to 6 weeks before your desired transplant date, which allows seedlings to reach transplant size while still in cooler conditions. Approximately 16,000 plants can be grown from one ounce of seed.
Transplant seedlings outdoors as soon as soil can be worked in spring, as this is a frost-tolerant crop that thrives in cool weather. Space plants 6 inches apart in rows 12 inches apart. Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days before final planting.
Direct sow seeds outdoors in spring as soon as soil is workable, or in late summer for a fall crop. Sow seeds at the depth indicated on your seed packet, keeping soil consistently moist until germination occurs.
Harvest leaves at 28 days from sowing, or begin picking outer leaves once plants are large enough to handle, usually within 3 to 4 weeks. For a one-cut harvest, simply cut the entire head at soil level using a clean knife. Harvesting in the early morning when leaves are crisp and full of moisture yields the best quality. In cold weather, you can extend the season by holding freshly cut heads in a cooler at 35 to 40°F for up to two weeks before final use.
