Revisit Canna 'Stuttgart'

A tall Foliage Group cultivar; green and white variegated foliage, oval shaped, upright habit; half-round stems, coloured green; spikes of flowers are erect, self-coloured apricot, staminodes are long and narrow, edges regular, fully self-cleaning; fertile both ways, not true to type, self-pollinating, capsules round; rhizomes are long and thin, coloured white; tillering is prolific. Introduced by Bob Hayes of the Brooklyn Botanic Garden, USA.

Has a synonym 'Striata', but this is patently not correct as that is a separate and distinct cultivar correctly named C. 'Bengal Tiger'.

The variegation is due to mutation in meristematic tissue of an otherwise normal plant. The mutation involved the loss of the chloroplasts in the mutated tissue, so that part of the plant tissue has no green pigment and no photosynthetic ability. This mutated tissue is unable to survive on its own but is kept alive by its partnership with the normal, photosynthesising tissue.
