Blue lettuce is a striking European perennial with lavender-blue daisy-like flowers, thriving in full sun and well-drained soils. It is relatively undemanding once established and tolerates poor, rocky soils typical of its native Mediterranean and central European habitats. Plant in a sunny border or wildflower garden and water regularly until established, then reduce frequency.
