Answer: Cephalaria is in fact yellow Scabiousa. These hardy perennials are natives of Europe and grow up to 6 feet high with a spread of 4 feet. Cephalaria gigantea, the Giant or Yellow Scabiousa, is a vigorous growing plant with dark green leaves divided into lance-shaped sections. The beautiful, large, pale yellow flowers are borne atop wiry stems in mid-summer.
Cephalarias should be grown in fertile, moist, but well-drained soil, in full sun. They are suitable for large borders and for naturalizing in a wild garden.
You may have confused Scabiosa, the pincushion flower, (family Dipsacaceae)with yellow scabiousa (Cephalarias). It happens often when we use common names instead of botanical names when referring to a plant.
Hope you enjoy your plants, regardless of their botanical name!
