It is very hardy for me, but I have had it growing outdoors for ten years so it may be that my specimen is well adapted. It got down to 26 a few weeks ago and it sustained no damage, I was very worried because my area rarely gets that cold. I covered it with a tarp as it’s just too huge and hazardous to move. It grows in a southern exposure but has very tall conifer cover, which protects it from sunburn and winter frost. I just love this plant! It’s so hard to repot.

It is etiolated but healthy -- about 3 feet tall and has just started a new branch near the base. This plant is not thought to be very frost hardy, and mine is covered by a 6 foot tall fabric cold frame in winter. Even so, my E. grandicornis has survived some freezes so harsh the elephant food (Portulacaria afra) right next to it was killed.

Seasonal growth pattern, almost all in spring and summer, but very fast when given space and water. Nice yellow flowers. Plant may be self fertile.

Doe...Read Mores 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.

Like all Euphorbia HANDLE WITH CARE, the latex/sap is dangerous and can cause skin rash, itching and general discomfort.
