Ohhhh beautiful daffodils! 
I can’t recall seeing double heads on a full daffodil, but the miniature daffs we get at the stores here in Poland often have multiple heads on one stem. Although I’m not sure if the miniature version is indeed just a mini, or if it’s a different type of narcissus 
I did a search and it looks like a few years ago in the UK, a girl found a daffodil with ten heads on one stem 
! Perhaps daffodils are in their element in the UK and thrive over there 
Magickally, I wonder if it could be similar to how mushrooms spring up in Fairy Rings- could extra-happy plants also be a sign of the Fae? Or perhaps that a nearby witch has strong green magick? 
I don’t have any set answers here, but I do love hearing everyone’s thought and I always enjoy a plant discussion! 
Thanks for bringing it up, @IrisW!
