It has tongue-shaped leaves, heart-shaped at the base, which are slightly longer and wider than those of the leaf rosette . The compact, equilateral inflorescence consists of forked coils and usually several, small, axillary coils. The short-stalked, 14 to 16-fold flowers have a diameter of 3 to 3.5 centimeters. Their oblong, ovate, blunt petals , bare on the inside, are reddish at the tips. The linear-lanceolate sepals are greenish yellow, have a green stripe in the middle and are lilac-colored at their base. The stamens are lilac-colored, the bare anthers yellow. The nectar flakes are oblong transversely.
