We purchased a large epiphyllum from a fellow nursery a couple of years ago. It was rootbound and not taken very well care of but our love of epiphyllums told us to give it a go. The first year, the blooms appeared red on the outside...it was simply marked "Red Epiphyllum." I only got to see one bloom open almost completely...the others fell off perhaps from the shock of being moved. The next year, I repotted it...fed it...kept it in filtered sunlight except for in the winter where it rested in a shed when it was too cold to be outside. It did get to experience mild cold temps which I hear is good for bud production. 

This was pics of the first bloom we had to go by. I began to call it the "Red Noid." I also sold cuttings and plants of it labeled..."Red Noid."

So, after the great care I gave it, this year it loaded itself up with almost 50 buds. I anxiously awaited their opening. The buds were a bright red. I was still believing they would look like a Red Noid. 

However, to my surprise, the flowers opened in shades of red and pink. I decided I could no longer call it a "Red Noid" but instead..."Valentine Noid."

To further complicate things, I noticed some buds did not appear dark red as most. They were lighter yet opened darker. Please see the differences in blooms below.

Now, I'm tempted to call her 'Crazy Beautiful' Noid. lol The only explanation I have gotten for the variances is that she is a "multi hybrid." So, if you purchased a 'Red Noid' from me in the past, you will probably be strangely delighted to experience these same variances from bloom to bloom. :-)
