Looks like night-blooming cerrus to me. Sorry,don't know where you might find it. Joyce

Look for the thread called "night blooming cereus". Some one identified the plant as a Epiphyllum oxypetalum, which I think is the same as your pictures. They said you can get it from Logee's.

The scientific name is the night-blooming cereus which blooms at midnight for one night for a few hours and its found in desert kinda places like southern america and part of some succulant/cactus family. After the flower blooms a red fruit grows which is apparently edible.

ah! u were watching Wolfs Rain no? i just finished the series! i loved it! do u know where i could get some lunar flower seeds and just more info on them as well
