Canna ‘Queensland Arrowroot’
syn Australian arrow root
Blooming Outstanding bloomer
Canna ‘Queensland Arrowroot’ is a giant Agriculture Group cultivar; green foliage, very large, oblong shaped, spreading habit; oval main stems, coloured green; spikes of flowers are erect, self-coloured red, staminodes are long and narrow, edges regular, petals red with farina, fully self-cleaning, outstanding bloomer, blooms open in the early morning; fertile both ways, not true to type, self-pollinating, capsules globose; rhizomes are thick, up to 7 cm in diameter, coloured pink and purple; tillering is prolific.
A hybrid, transported to Australia where it has now become an environmental problem in the wild, because it is so prolific. However, the temperate northern climate restrains it, and there it is a remarkable architectural specimen. Has the potential to be grown for conversion to a biofuel, due to its high rhizome starch levels.
