The flowers are in a terminal head-shaped inflorescence . The spherical flower heads have several rows of bracts on the outside . The bracts are 6 to 7 mm long and 3.5 to 4 mm wide. In the bottom of the head there are 9 to 12 mm long and 2 to 3 mm wide chaff leaves . Bracts and chaff leaves are hairy, silky and shaggy, rarely bald. The calyx and outer calyx are dry-skinned and bristly. The outer calyx, consisting of two intergrown pre-leaves, has eight awl teeth of unequal length, four teeth are about 1.5 mm long, the four teeth in between are about 1 mm long. When the fruit is ripe, the outer calyx is about 9 to 12 mm long. The hermaphrodite flower is fourfold. The four sepals are fused together to form an upwardly curved calyx, calyx teeth are clearly visible. The crown is yellowish-white, hairy on the outside and four-lobed. The two carpels are one under constant ovary grown.
