Green and Red lettuce, with Arugula Red Russian Kale, Ruby Steaks Mizuna, and Endive. New for 2018: We added a touch of ruby streaks mizuna and endive for even more diversity. Great from micro-greens to maturity. Note that this mix requires regular managing, aka thinning, especially when the arugula and kale get big. This mix can't be planted too early - plant in the fall, or any time in spring. Sow 1 cm (3/8 in) deep, with rows around 30 cm (1 ft) apart. Thin as desired. The plants can bear light front both early and late in the season.
