The composite family, Compositae or Asteraceae, also known as the sunflower family, is one of the largest in the plant kingdom with nearly 25 thousand species of composite flowers, worldwide. The composites have flower heads that resemble an individual flower, but the head is actually made up of numerous individual small flowers. The composite family is important to the honey bee because many of its members are prolific producers of nectar and pollen. I will list a number of composites; as well as being beautiful wildflowers, many have curious names: pussy’s toes, mayweed, or dog-fennel, Philadelphia fleabane, wooly ragwort. Other composites include the asters, sunflowers, common milfoil or yarrow, burdock, daisy, bur marigold, Indian plantain, common chicory or blue sailors, and thistles. One thistle, knapweed or star thistle, is known for making honey. A number of composites are recognized as common plantings in the flower garden: coneflower, cornflower or bachelor’s button, and ox-eye daisy. Many composites are wildflowers found in meadows and clearings in woodlots: tickseed coreopsis, daisy fleabane, American feverfew or wild quinine, mist flower, boneset, Indian blanket, rabbit tobacco, black-eyed Susan, groundsel, and Joe-Pye Weed. Some composites should be grouped according to their descriptive names: bitterweed, sneezeweed camphorweed, and stinkweed. Important late-season bee plants from the composite family include Canada goldenrod, the many asters, and dandelion. The over-winter food for many colonies is derived from these composites. The survival of many honey bee colonies is often dependent upon a composite wildflower, the dandelion, the last plant to bloom in the fall and the first to bloom in the spring.
Composites of economic significance include lettuce, chicory, chrysanthemum, artichoke, and sunflower. As I am visiting my bee yards at this time of the year, I am finding a few composite flowers in bloom. Whenever we see some bees bringing pollen into the hives at this time, it is usually from composites. Today’s photo shows a honey bee foraging in a perennial sunflower, the Jerusalem artichoke or sunchoke.

Are these flowers blooming now? On the warmer dryer days my bees are still out foraging and returning with golden pollen but the source is a mystery.
ReplyDeleteNice photo.
Shirley, the sunchokes, perennial sunflowers, seem to have just completed their bloom that lasted for a number of weeks. I am finding the bees foraging on a number of composite flowers now. Here in the third week of November I found them foraging asters, bitterweed, common dandelion, and another species of dandelion. I also found honey bees foraging buttercups, which I did not expect to bloom until early next spring. The bees bringing in pollen now probably means that you will have young bees to start feeding the brood early next year. I’m enjoying following your bees.
