Around 3-4 years ago I obtained some seed from a seed exchange that was
supposed to be Digitalis lutea, however after looking at various pictures on
the web I am wondering if it might be D. grandiflora. Does anyone have any
definite identification points to look for in comparing the two plants?
The plants I have appear to be reliably perennial - I have one which is 3
years old.
I have posted some pictures on my web site @

For reference the plant pictured is one year old and 45cm high (18 inches).

Thanks
