The leaves are a bit pale !! maybe it is in need of a feed, the ones Ive found for you could be either 'Kings Ransom' Dilly Dilly' Midnight Sun or even Torch ' sorry I cant be more specific but they are all of a sameness.

Thankyou Maggie I have been feeding them and bought them for their foliage .

But they did not have name tags when I bought them.

Maybe when the lighter one blooms we will have a better idea of the name.
