Musa basjoo
The Japanese banana is the hardiest banana species in the world and brings a truly tropical feel to the garden with its enormous, fan-shaped leaves. The plant can reach up to four metres tall and grows at astonishing speed. The above-ground parts die back in winter, but the roots survive temperatures down to -15°C and reshoot vigorously in spring.
Plant in a sheltered spot in full sun or light shade in fertile, moist but well-drained soil. Water abundantly in summer. Feed weekly during the growing season. Cover the root zone in autumn with a thick layer of mulch or straw for winter protection.
In autumn, cut back the dead leaves and pseudostem to about 30 centimetres above the ground. Cover the remaining stump with insulating material. New shoots appear quickly from the rootstock in spring.
Canna indica

Hedychium gardnerianum
The ginger lily is an imposing tropical perennial with broad, lance-shaped leaves along tall stems, crowned by large spikes of bright yellow, wonderfully fragrant flowers from August to October. The sweet, exotic scent carries far through the garden atmosphere. With protection the rhizome overwinters in temperate climates.
Phormium tenax
