My plant above is in a 3 1/2" pot. The plant is grafted on a Harrisia stock. The plant originates from Brazil. The cephalium is made up of white wool and red bristles. This plant is also rare and sought by many cactus collectors. The nocturnal flowers grow out of the cephalium. They are white, to 3" long and 3" wide, and have a strong fragrance.
