Hi there norma. Not sure what more info to give. He is in a five gallon pot. Stays on the dry side, fertilize once a month with miracle gro nursery select 20-20-20. Morning to afternoon 3 pm sun. I've been spraying here and there with daconil. This cracking just started last year. Only appears to be on the thicker parts of the stems. No insect damage. Doesn't seem to affect anything else. Just deep v groves as you can see. Also he has never flowered in the whole 3 years I've had him. Just seems to wanna grow. Don't know if the weight of the newer stems is putting stress on the main "nubs" and all that weight. As I have seen these guys more trellis like. While mine just hangs.

It's a type of epiphytic cactus, like Rhipsalis is, but it's its own genus. From Wikipedia - I too had no idea there were so many species. Hylocereus calcaratus - Costa Rica.

Stems green not glaucous, brown-margined. Flowers 28�"31 cm long, 24�"36 cm wide. Hylocereus megalanthus - Stems green, slender without horny margins. Flowers 30�"38 cm long with large flattened tubercles and small bracts. Flowers similar to Selenicereus. Fruit yellow. Hylocereus minutiflorus - Guatemala, Honduras. Stems green. Flowers with rigid spines at base of flower, 5 cm long, 8�"9 cm wide, white. Hylocereus monacanthus - (incl. Hylocereus lemairei) Costa Rica to N South America. Stems gray-green without horny margins. Flowers ca 30 cm long, petals white, tinged pinkish near base or entirely pink. Tube with distant bracts. Stigma lobes usually forked. Fruit red with purple pulpa. Hylocereus ocamponis - (incl. Hylocereus guatemalense, Hylocereus purpursii) Mexico & Guatemala. Stems white-waxy, margins horny, spines needle-like, to 12 mm long. Flowers 25�"32 cm long with white inner petals. Bracts overlapping, with purple margins. Hylocereus setaceus - Stems green without horny margins, rather spiny. Flowers 19�"22 cm with small tubercles and bracts. Flowers similar to Selenicereus. Fruit red. Hylocereus stenopterus- Costa Rica. Stems thin, soft, green.

Cris, there is a species by goes by the common name of Dragon Fruit It grows up in trees, and is tropical. The fruit comes in yellow, Red, with lots of seeds inside. I have told that it is wonderful. I saw pictures of this fruit a couple of weeks ago, but I can't eat it because of the seeds. But this will give you something to go on. The leaves of this plant are three sided, and a member of the cactus family. One of the gals at the Huntington Gardens showed it to me at the last sell, the plant sells very rapidly. Norma

I'll try to find a pic of my uncles short fruiting DF. I'll also test it with one of my one cuttings and let everyone know how it goes. My uncle topped his plants in a pot when they were about 4ft tall and he also cut the side branches when they were about a foot or so. He had to prune occasionally to control for size and shape. Now looking at the picture I posted, I'm pretty sure that the plants were grown in the typical fashion (Full Sized) and then the fruiting branches were cut and stuck into pots. If they were grown in the pots and fruited in those pots, I would expect a lot more side branching like I see on my uncles potted DF.
