We have 2 large patches of Jerusalem Artichokes in our forest garden which have begun to bloom now :) Such a blessing for the bees when fresh pesticide free pollen is needed to create winter bees. Bees use pollen to create fat bodies (Vitellogenin) in their abdomen which makes them live long up to 6-12 months. I can see bees bringing in orange, yellow and white-grayish pollen at this time. Not much pollen though but still better than nothing.
Bees are eagerly collecting nectar and pollen from Jerusalem Artichokes flowers
The Great Willow Herb is still in the bloom. Note the whiteish pollen
