Epimedium perralchicum Frohnleithen

How do you propagate these, can they be divided?

Yes, spring or autumn GG. Have never tried to divide these yet. If and when iI do I think I'd do them in the spring. That way you don't have to wait too long to see if it works.

Ah good, I think my Mum has this in her garden so I'll add it to my list of her plants I'd like a bit of! I say 'think' as she wasn't sure what it was, except that "it had yellow flowers that have now gone", but I reckon it was this from the leaves ...

Let me know how it goes GG.

Will do, I got the ID right at least which is a good start - showed her your photo and she said the flowers look the same as hers did ;o)
