Epiphyllum blooms are Delicate, Beautiful and Exotic flowers.
Unfortunately, they last only 1 or 2 days before they wither.
If I'm lucky, I may get to see and enjoy some of them for maybe 10-15
minutes after they bloom.
Lately I pick the bloom as soon as it opens and put in in a vase
containing a dilute sugar solution. Then,I put he vase and flower on my
kitchen table so I can view it all day long..... maybe 2 days
It makes a very nice showy display.
