Canna 'General Eisenhower' is also known as 'Tropicanna Black', this canna grows well and is worth making a little space for. C. 'General Eisenhower' has lush, glossy and very darkly coloured foliage which contrasts so well with the rich orange-red flowers, a real show stopper! So much so, it has been awarded an AGM by the Royal Horticultural Society.
Canna are suitable for a container or for growing directly in the ground. Feed well for optimum growth during the growing season, plant in a sunny sheltered spot in a humus rich soil. Canna prefer a well drained soil if you want to overwinter in the ground. If you leave in situ, mulch heavily in autumn to protect from winter frost and place an upturned pot over the crown, this acts as a cloche and helps keep the rhizomes dry. Alternatively you can lift the rhizomes and store dry in a frost free environment for the winter.
