Gardeners' Notes:

Gardening in Saint George, UT, I try to use plants from the
local natural flora and add plants which use the least amount
of water, while tolerating the soil conditions without adding a
lot of amendments. I planted three "gopher plants" about 3 yrs
ago and I've found them to be quite successful here. However, I now have an abundance of the plants which have
volunteered in areas far from irrigation. This works okay for me and I've found it's easy to control the spread by just pulling the new starts from the ground. I enjoy the color contrast they add to my garden, but I do have one negative to report. They have spread to my neighbor's property and he has become uneasy with this. He liked it at first, but a recent TV NEWS warning has him concerned. I'll help him with this matter, but be aware that these plants can spread themselves far and wide and could cause issues with neighbors.

Does anyone know where I can buy it?

I have had two of these in my front yard (planted last spring) they did not spread but did get rather large for their respective spots. Today we moved them into a large planter box. I separated the roots and created 6 smaller plants for an even distribution. We were very careful and wore gloves b/c I'm pretty sure the sap of all or most euphorbias are poisonous and cause a pretty bad rash/reaction. I did not break any stems or expose any sap but would like to note that I did brush against the plant several times with my forearm and the succulent leaves caused absolutely no reaction. Look up the plantfile for "Euphorbia myrsinites" as these two plants are very similar. You will find a lot of negative reviews about spreading and sap problems. I don't think I will have the spreading problem here in Vegas in my Xeric/Desert landscape as I'm sure they need water to spread!

Bought two of these and put them in a stucco plant box in my front yard. As of 2008 they continue to grow well. I love the green flowers. Last year they were in full bloom for St. Patrick's Day - very nice!
