Early season flowers for bees and butterflies

Three species of butterfly seen on the plot this weekend with the warm weather - small tortoiseshell, peacock and comma. And plenty of queen bees coming out of hibernation and bumbling about. Here's a few nectar sources for them from around my plot and garden:

Crocus

 Rosemary

 Cherry plum blossom

 Erysimum "Bowle's Mauve"

 Hellebores

Pulmonaria
