Which part? Or both?
McKana aquilegia are not true hybrids. They have been selected in the normal fashion of plant breeding. This also applies to 'Russel' hybrid lupins (I tend to see them referred to recently as a strain, which is more accurate) and also to 'Pacific Giant' hybrid delphiniums.
The breeder trading on the word hybrid? The horticultural world is full of people with something to sell trying to associate their product with something else that is successful. Probably the most famous tomato over here is Burpees's 'Big Boy'. So what else is available that sounds similar? 'Better Boy', 'Big Girl', both available from Burpee's, last time I looked, but both with significant differences from 'Big Boy'. Marketing is the name of this game. Like the rest of the world?
