I have another in another room in a plastic pot, different window direction. The plant’s been moved around till I thought it liked a spot.they have grown. the one in a south/west window has surprised me with a flower; today it opened!!! It’s very large. There’s another blossom on same stock. How long will it last? What is the plant’s name? Need info; lots of info. It’s soooo beautiful!!!!! help!!! – Tina

I believe it is a type of Epiphyllum or Nopalxochia.
Possibly a Epiphyllum ackermannii or Nopalxocia ackermanii, sometimes know as the red orchid cactus.

Not sure how long the bloom will last.  Typically they last for 3 or 7 days.

They do not like temperatures above 100 degrees. The blooming cycle usually occurs between late winter and early summer. They grow best in a cactus mix potting soil in bright filtered light with moderate humidity.

During the growing season, apply a diluted water soluble fertilizer once a month.  Keep it well watered except in the dormant season when it needs to be kept on the dry side.  Growing season is some between late winter and the beginning of fall.  Watch for mealy bugs especially in the spring.

I hope this information is helpful. Please let me know if I can help with anything else.
