Sow in pots or slabs at a temperature of 10-18°C, one month before planting. Cover the seeds with a thin layer of soil, press lightly and water. Once the plants have 4 leaves, prick out. Alternatively, sow in rows 30 cm apart, every 15 days, to stagger harvesting. Thin to 10 cm, then 30 cm. This type of sowing produces hardier plants, less susceptible to bolting.

This variety was selected by Frank Morton in Oregon. According to him, all these "mini-Romaines" are the most resistant strains to bremia, the lettuce mildew. The optimum in horizontal lettuce resistance is on a par with the "Merlot" variety, one of the Tribe's ancestors.
