Dr. Doug Beilstein of Ohio registered this cultivar of unidentified parentage from a seedling obtained from Japan;.. in 2007. It is a giant size plant about 32 inches high by 72 inches wide with shiny, dark green foliage. Pale lavender flowers bloom in July.

The originator made the following comment on the Fraternal Order of Seedy Fellows website: "A dear friend and mentor Bette Comfrey of Silvermist, located in Pennsylvania, was so kind and free with her help and inspiration that I named a seedling she gave me after her. It grew out of seed Bette got from Japan from Toyozo. When Bette closed her Silvermist I obtained from her many of the plants I use today in my breeding program. Not Available."

This was named for a friend and fellow gardener Bette Comfrey of the former Silvermist Nursery in Pennsylvania.
