Giant salvia (Brillantaisia cicatricosa) belongs to the Acanthaceae (the Acanthus family). It is a soft-wooded aromatic shrub that is distributed to eastern Africa, from Uganda-Kenuya south to Zimbabwe-Mozambique. This shrub grows in highlands and up to height of 2-5 m. The leaves are more or less broadly ovate, sometimes purple-tinged, 10-40 cm long, with a winged petiole and coarsely toothed margins. The mauve, salvia-like flowers bloom in large spikes from August to September. Corolla has a upper lip covered with purplish glandular hairs, and a 3-lobed lower lip.
