Tillandsia caput-medusae is a robust plant that is adapted to drier habitats. The grey-green leaves are leathery, long and twisting, while the inflorescence is long and bright red. Tillandsia ionantha forms a bulky rosette 8 to 10 cm high, with triangular, leathery leaves that are superimposed and highly erect. The lower face is scaly and greyish. Before flowering, the tips of the central leaves turn a stunning pink. When the plant blooms, violet flowers with long yellow stamens appear in the centre of the plant. Tillandsia lindenii has foliage that resembles that of Tillandsia cyanea. Its 30 cm long inflorescence is bright pink and the 5 cm flowers are deep blue with a white throat. Tillandsia usneoides, or Spanish moss, resembles some lichens. In the wild, this tillandsia hangs from trees. The bare rootless stems that can grow up to several metres long are covered in small silvery green thread-like leaves. This species is generally grown suspended from trunks.
