I bought a double narcissus, White Medal, from Scheepers a few years ago. Except for the first spring, in the two years since it has formed buds and then they have dried up without ever opening! Is this typical of large doubles? Or is it something I am doing wrong?

I have smaller double types like Cheerfulness and Bridal Crown and they bloom and open reliably: some right next to and at the same time as the White Medal. Foliage looks very healthy. I gave these WM a very prominent spot. If this is a freak occurrence I will let them stay: otherwise itÂs off to the back with them while I wait for them to clean up their act.
