I have five Easter Cactus to add to the Database but I have no place to put them. The subject line is what I would suggest we use since they can be one or the other and most people do not know which they are since the growers do not specify when selling many times. The common name should be Easter Cactus. The cultivar can be added if the grower gives it one. Many sold in Home Depot, Lowes, Acme and not sold with tags. But they are either Rhipsalidopsis or Hatiora, mostly Rhipsalidopsis I would guess. Botanical Rhipsalidopsis are made up of two species Rhipsalidopsis rosea and Rhipsalidopsis gaertneri.
Check this out before you decide.
