Elegance – Of unknown origins.
Supposedly a form of
'Sulphurea', with blooms that are
a deeper shade of creamy buff, though this is not always the case. The flowers of this cultivar are extremely
variable with a number of colouring variations being reported. It would seem that the change in colour can
be attributed to the soil it is grown in; nevertheless, an extremely
interesting violet.
