The Cretan dog's tongue is a biennial, 20–80 cm high plant. In the first year of growth, only a rosette of lanceolate, dense, soft and hairy leaves is formed. In the second year the inflorescence appears . The leaves are sessile in the upper part of the stem, encompassing half of the stem and often without distinct lateral nerves. The short-stalked flowers appear in bractless coils , they are initially pink, later pale blue with strikingly dark nerves. The corolla of the flowers is 7–9 mm long, the blunt, five-lobed, bald border is about as long as the tube. The fruits are convex nuts, 5–7 mm wide, densely covered with barbed spines, without a thickened edge.
The Cretan dog's tongue blooms from April to July.
The number of chromosomes is 2n = 24, less often 48.
