Usually, Foxglove flowers droop downwards but one variety, known as 'Candy Mountain', has flowers that have the opening pointing upwards. Otherwise, it's the same as a standard Foxglove. In my garden is a rather different-looking specimen. The flowers are set with the opening at the top, like the 'Candy Mountain' variant, but it also has a large flower at the apex of the stem, which is unlike any Foxglove I know of or which the interwebz seems to have any record of. The question is, do I have a novel variety or not?

Great. Thanks for that. Given that it's seeded from previous years' plants, this one has also got the mutation seen in 'Candy Mountain' of upright-facing flowers, so it's a serious mutant.
