The flowers, bracts, and sepals of the blue eryngo are hued in a light blue or violet color that attracts insects - flies, butterflies, and other pollinators. The plant prefers dry and sunny places. The firm, smooth and even waxy exterior of its shoot provides excellent protection from the plant drying out even in intense sunlight. The light blue color also protects it from the negative effects of excessive sunlight. The poorer and drier the soil that the blue eryngo grows in, the more pronounced its shoot color will be.
