Orchid Cactus or Epiphyllum

Orchid Cacti are also know as Epiphyllum. The word Epiphyllum in Greek means "upon the leaf" and the flowers appear to bloom directly on the leaves. The species is native to the jungles of central and south America as well as Mexico.
A friend of mine gave me this purple red orchid cacti plant a few years ago. She said it's a more compact plant than the white one and the flowers can last at least a couple of days, not like the white one that I had long long time ago. It grew so big and vigorous, and bloomed many flowers with strong perfume. The flower opens as soon as the sun goes down and stays open all night , then closes in the morning. Very often, all you can see is the wilted flowers in the morning. So, what the heck! I said no more to this plant, and that is the end of it.

I don't have this plant any more. This picture is from magazine
