The rain will get them every time. But, not to worry, these daffodils almost always come back upright. Drier weather is predicted, for what that is worth, and we really need the rain anyway.
Daffodils have been blooming all around town, and I saw them in full bloom on a drive to the coast (60 miles away) 10 days ago. Mine are not quite at full bloom yet. We always have blooming daffodils on the first day of spring here. Though on warmer years, they are almost done, on that day. Still 10 days to go, but I don’t think that warm of weather is expected. Once the sun starts shining, the flowers bloom and die so fast. This is a positive note for overcast, 60 degree (F) days.
