Around here (S. England) Rosebay Willowherb or Fireweed (Chamaenerion angustifolium) is an important summer bee flower with a striking grey-blue coloured pollen. I see it coming in every year in the summer. Dorothy Hodges' book, "The Pollen Loads of the Honey Bee", shows the following plants with blue pollen that bees have been known to collect:- Siberian Squill (Scilla siberica) Garden Bluebell (Scilla sp.) Vipers Bugloss (Echium vulgare) Garden Campanula (Campanula sp.) Purple pollen.
