Rainy Side Notes
Cephale is Greek for the word head. Member of the teasel family and closely related to Scabiosa, it was one time in the same genus. This tall perennial needs room for growth. It is a coarse plant, so grow it at the back of the border.
With the flower’s striking yellow color and long stems, it makes a worthy cut flower, as well as a good forage plant for bees.
