I thought it looked like a match to Erlicheer too
I was just on the porch looking out over the garden and noticed in the clump of what is supposed to be Spellbinder daffodils there was a bloom with a long, flaring trumpet that I was expecting! I thought maybe
@jmorth was right, and that the blooms are continuing to develop and showing their true features. Upon closer inspection I found that this bloom just opened this morning and is indeed Spellbinder!
Unfortunately, it is the only correct bulb of the 10, but I'll be happy to baby this one along in its own spot and let it increase into a clump
