I started these impressive perennials from seed over twenty years ago. They are growing on the street side of the orchard garden, seeding themselves around a bit every few years so that they haven’t died out altogether.
When growing happily, these plants can get six feet tall with dozens of pincushion-like (scabiosa-like, if you know what scabiosa flowers look like) flowers. The color is a soft cream and white. My own plants are too crowded to look their best.

Here is a Cephalaria survivor in November of 2020…notice that it is throwing up buds even at this late date.
Future plans for these plants are to move a division or two to the memory garden where they will do more than survive–and I expect their flowers will attract a lot of pollinators there in a sunnier spot.
