Is it an indoor plant? If so, you may both be right! I have a couple of plants (one red flowered, one pink) that are commonly called (are you ready...) Orchid Cactuses. They're actually Epiphyllums, and (this may make you feel better) I haven't had any luck getting them to bloom, either. But my mother, who originally owned my first plant, could get it to bloom once a year. What is it about mothers that makes them better at nurturing things? LOL

Have a look at these plants and see if it's the same kind. I tried to find a site
that showed leaves as well as flowers.

That is IT! Wow I have looked online for this plant for days. My mom's is the original also, and mine is a babe from hers. Anyway it is the night blooming cereus type. Gorgeous plant.
Thanks alot, I feel so complete now.

Glad I could help!

Orchid Cactus (Epiphyllum species): Orchid cacti prefer temperatures that range between 45 and 70 °F. They will tolerate extreme heat if well-shaded and the humidity is high.

Plants should receive balanced fertilizer once a month from spring to fall. It is always better to use too little fertilizer than too much. To encourage flowering use an application of low nitrogen fertilizer once at the end of February and again in early November. Do not fertilize plants during December or January.

The major flowering season for day-flowering orchid cacti is from April to June. Night-blooming species flower in late summer and early fall. Epiphyllums will flower when they are 2 to 3 years old. Make sure that your plants have a nighttime temperature of 40 to 50 ° F during the winter. Plants like to be rootbound before flowering.

Orchid cacti have flattened, fleshy stems, often deeply toothed, with a trailing growth habit. Flowers are 6 inches long or more and of many colors. They are often sweet-scented and night-flowering. There are hundreds of cultivars.

Thanks for the growing (and blooming) tips, nman. My mother had her plant in a basement window. I was trying to grow mine in a second-floor window, and it probably never got cool enough to initiate bud set. Getting it that cool is going to be a challenge...
