Over 10 years ago, I stuffed the contents of a small hanging basket of this cactus into a crotch of a live oak tree, approximately 8 feet above ground level in my front yard near the sidewalk. It has grown with absolutely no care ever since. Funny thing is, I had no idea at all that this was at least a semi-epiphytic cactus. Just put it in the oak on a whim! The stems have grown as long as 4 feet. On several occasions it explodes in pinkish purple blooms, seemingly out of nowhere. Spectacular when that happens!

When I saw a photo of this cactus in bloom, I just had to have one. It's doing great hanging on my covered porch here in San Jose, Ca. Some of the "tails" have grown to about three feet long! looking forward to it blooming again next year.

This plant makes a great low maintenance hanging basket for desert or hot summer areas. The blooms in the spring are a great extra, but even without the blooms, it's a very interesting plant that provides something other than just green foliage. It's much more cold tolerant than stated here. I live in zone 8b and it survived temps of 14 degrees last winter with some die back but it bounced right back in the spring.

As houseplant here of course. A friend of mine gave me a little nubbin less than a half inch long. I have it in a sunny spot in a little clay pot with a piece of clear plastic covering it, kind of like a mini greenhouse. I hope it anchors and grows.

This is by far the ugliest plant that I own. But... the most hardy, so I gave it the neutral rating. My mother gave this to me a few years ago, and it was almost dead. Now it is thriving in all of it's ugly glory. I'm not sure that it is warm enough here in winter, so the tails all go fat, skinny, fat, dead, skinny, dead, fat, etc.. And now this winter only it has started producing very skinny little tails that are sticking straight up from the soil level. And it has the beginnings of it's first flower! If I didn't have sentimental attachment it would have been gone long ago, as I believe it needs a more consistently warm climate.

This is a popular trailing cactus- great for hanging baskets. Develops long, trails of 1/2" (2cm) diameter cactus that blooms a hot pink flower in early spring (at least here in California).
