Canna 'Uvurderlig'

A medium sized Foliage Group cultivar; green foliage, oval-acuminate shaped, transparent margin, upright habit; half-round stems, coloured green; spikes of flowers are erect, burnt-red streaked with red, staminodes are long and narrow, edges irregular, labellum is saffron-yellow with a narrow carmine margin, style is saffron-yellow, petals purple, fully self-cleaning; fertile both ways, self-pollinating but not true to type, capsules globose; rhizomes are thick, up to 3 cm in diameter, coloured white and purple; tillering is average.
Introduced by Malcolm Dalebö, Claines Canna Collection, Worcester, England, EU in 2006.
This is another member of our "back to basics" experiment, where we replicated the species crosses made in the 1840's and onwards to see what we could produce. The achievement with this second generation cross was producing flowers with petals (staminodes) much larger than the species. This cultivar remains part of our breeding programme and will be crossed with more species to capture more of the basics, but also will be crossed with modern Premier Group cultivars to understand what such a cross will produce.
