your bees are clustering tightly during the winter months, there are
some flowers that bloom early February/March that give nutrients to the
bees. If there is a nice day here and there, the some bees will stretch
their wings and take a flight. Here are some plants that attract bees
and local pollinators this time of year:
Shrubs: Goat Willow and Oregon Grape.
Perennials: Hellebore, Primrose
Bulbs: Winter Aconite, Crocus, Snowdrop, Siberian Squill
Along with low ground plants that offer good sources for nector and
pollen, trees are equally, if not more efficient in offering local
pollinators an abundance of nutrients. Trees that give a great source of
either/or pollen and nector are Apple trees, Sweet Cherry, Horse
Chestnut, Mountain Ash, and Little-Leaf Linden.
