I love the bright colors on yours. Mine plain old white one bloomed last year but when it was pouring rain so I only got a few water-speckled pictures in between & it was too cool & wet to smell it. I kept it on my patio table under an umbrella where it got early am & late afternoon sun & sprayed it with the Recipe when the Brugs got it. It seemed really happy there because it was only a little bitty one-leaf-cutting the previous fall. I just put it back out there the other day so I hope it blooms again this year. Linda

Xuan, That's a nicely grown plant - in your area of Vietnam I'd bet almost any jungle cactus would do well, and yours are even better than that. I don't mean to rain on your parade, but I can't agree that it's a yellow flower - it's a white flower with yellow outer petals (not uncommon in the night-flowering jungle cactus world).

Thanks for the help, but now I have more questions! After getting this plant from my neighbor and figuring out what it was, I became interested in the species. I then swapped some other stuff for an oxypetalum (which hasn't bloomed yet). The leaf tips of the oxypetalum I got are rounded. The leaf tips on this one, as you can see, come to a point. I live in Tampa, and it's been excruciatingly hot this year. The plant hangs under a tree (I only brought it in to watch flowers open). The first night one opened, I had it inside my bedroom and there wasn't much fragrance at all. If I shoved my nose directly into the flower, I got a small wiff, that's all. I know there are millions of epi hybrids, some white. Are there different types of oxypetalums too? If this is the oxy, what's the other one I have with the rounded tips? Lori
