A striking plant from Venezuela that needs a sunny position with excellent drainage and a weekly watering during hot summers. Erect to rounded shrub with large, softly hairy heart-shaped leaves. From mid-summer to frost, 2-foot long, dark purple flowering stems bear tubular deep-red flowers with contrasting dark calyces and a flared lower lip, in widely-spaced whorls. Little pruning required, just trim off spent flower stems occasionally. Only hardy to light frost. 1.2m H x 70-90cm W. 1 litre pot.
