Best lettuce variety for Bengaluru terrace?

Best lettuce for Bengaluru containers: Red Oak Leaf (heat-tolerant, attractive), Green Butterhead, and Lollo Rossa. All grow year-round in Bengaluru's mild climate. Harvest outer leaves from 25 days — cut-and-come-again. Summer varieties resist bolting better in Bengaluru's warmest months March–May.
