Orchid cactus aka Epiphyllum - and I don't know about it needing to be planted that way, mine are just in soil. But then, I'm not in the tropics.

If you grow orchids on trees, this plant would be similar, an epiphyte.

Here we grow them in pots in coarse cactus mix. mostly shade, just a little direct early morning sun. water when it's warm, don't water when it's cold.

alright then, so how do I propagate this? the leaf is about 11 inches long, do I cut that leaf into two and let them 'cure' before I put them into a cactus mix?

Let it cure (dry) for several weeks. I wouldn't cut it in two, but you could -- then let cure for two weeks.

After two weeks, stick the end in a pot of very well draining fairly dry soil. Do not water until roots are beginning to form.

There's lots of information on-line about propagating epiphyllums from cuttings.
