There are two lots of OSR around me. The bees missed the earlier fields of it as the weather was too cold. The later-flowering stuff is still yielding.
Horse chestnut is in full flower.
We have a laburnum in the garden that usually flowers at the end of April. It is in flower now - a month later than most years.
My hay fever is just starting from grass pollen. It usually starts in early-mid May. So late again.
May your bees read the same books as you do.
