Flowers beginning with F

Remember this? Flowers you're growing or intend to grow with names beginning with E. 

Well, I've been waiting patiently for VC to carry one with the alphabet...but I think she may have forgotten there's a few more letters after E!


So here you go with the letter F

FOXGLOVES - already growing in the greenhouse. They don't seem to self seed for me.

Has anyone grown Lutea? The small yellow perennial foxglove.
