A medium-sized epiphytic bromeliad forming stemless rosettes up to 50 cm wide. The narrow, recurved leaves are dark green with reddish-brown striations at the base. The distinctive paddle-shaped inflorescence features densely packed rose-pink bracts up to 16 cm long, from which fragrant violet-blue flowers emerge successively. The species name "cyanea" refers to the deep blue color of the flowers. Formerly classified as Tillandsia cyanea, it was reassigned to Wallisia in 2016 based on phylogenetic analysis.
