Tillandsia setacea Sw.
Epiphytic perennial with erect, rigid leaves, to 30cm long, and flowers in dense spikes with red, yellow-edged bracts, each bearing a tubular white flower. [RHSD, Hortus].
Torenia asiatica L.
Frost tender, trailing annual with serrated, lance-shaped leaves, to 5cm, and stout, axillary racemes of tubular, dark purple-blue flowers, with violet lateral lobes, blotched with purple, in summer. To 25cm. [RHSD, Hortus].
