fum to compare

Are the leaves different?

One on the right is a more robust plant with longer leaves but otherwise very similar. Perhaps I don't use the correct terminology by referring to two different types, I was just referring to the interesting flower variation between two plants of the same species purchased more than 10 years apart.
