Fritillary

Most of the daffodils in the new daffodil bed have come up blind this year, once again. Contrariwise, the tulips in the same bed seem to be breeding and coming up fine, with flower heads. So what do the tulips know which the daffodils don't?

The snowdrops and winter aconites are also missing, but the snake head fritillaries seem to be doing alright, as illustrated. Maybe they are breeding too.

PS: maybe there is a lonely aconite leaf head showing through, just below and to the right of the fritillary front middle. But no flower bud to be seen, at least not yet.
