A horticultural hybrid of the American black chokeberry and European mountain ash was produced on the brink of the XIX and XX century by the Russian hybridizer Ivan Michurin, then adopted all across Russia and by many European countries, from where it was brought "back" to North America. The plant appears to be the only existing heritage from Michurin, whose other hybrids did not stand wars and years of neglect. Being imported from Scandinavia, it acquired a cultivar name 'Viking' in the US. Photographed: our first own crop (2005).
