Just recently noticed that the flowers have a sweet scent similar to that of Narcissus! A plant kept in an enclosed greenhouse had me thinking there was a misplaced flat of bulbs, but as I sniffed around, the culprit turned out to be E. grandicornis!

These grow wild here in South Texas. They are also called Zig Zag Cactus. If you have goats or cattle, they will eat this plant on the edges , trying to avoid the spines. It seems the latex doesn't bother or irritate the animals, truely weird!

Common potted and landscape plant in Southern California. Has great angularity and large spines making in a good ornamental choice. Does tend to rot easily if overwatered (found that out). Is not that delicate, though, in terms of brushing up against it and damaging it releasing sap... you have to hit it pretty hard. However, the spines can be quite hazardous, making moving or trimming this plant a chore. Plant can become enormous, often collapsing under its own weight eventually. However, if kept pruned regularly, this can be avoided. Makes tiny leaves in summer where the new growth forms, but usually devoid of leaves all winter. Flowers and fruits in late spring... flowers are actually quite striking and brilliant yellow, but usually on mature plants, and mostly those growing in full sun.
In southern California this is a very slow plant. My 6" tall plant grew into a monster in just 4 years, and now, 2 years later still, is over 12' tall and has (had- I trimmed most away) many gnarled and twisted branches forming an impenetrable wall in just a few years.
