Basket-flower by other wildflowers

Basket-Flower Flower Head from Side 3577

A month ago a flourishing colony of basket-flowers, Centaurea americana, appeared here, and yesterday a portion of a basket-flower served as a soft and pastel pedestal for a red admiral butterfly, but I’d be remiss if I didn’t show you a closer look at one of these flower heads in its own right. Today’s view is from Tejas Camp in Williamson County on June 1.

Most species in the Asteraceae, known as the sunflower family or daisy family or composite family, produce heads with two different-looking sets of small flowers: in the center are densely packed disk flowers, and radiating (i.e. ray-diating) out around them are ray flowers; think of your typical daisy and you’ll get the picture. Some species in this family, however, produce only one of the two kinds of flowers. That’s the case with the basket-flower, and even though you might think that it has white disk flowers surrounded by lavender ray flowers, all of them are disk flowers, despite the color difference. Not all that glitters is gold.
