I have a larger Medusa head which I have had for many years. I have grown several "babies" off of the mother, but suddenly the larger plant seems to be very unhappy. The arms are turning yellow, withering and falling off. It sits in close proximity to and gets the same treatment as another plant which is doing beautifully. Can anyone offer a suggestion?

It looks great, growing well in full sun in pot in my zone 10 Israel desert garden. But the chartreuse blooms are gone, will it rebloom?? Gardening here sure is a lot different from gardening in New York!!

my dad medusa head is as good as dead but i managed to save a few "hairs" or branches, i stuck them in the ground and they have grown roots now. i was wondering how a plant grown from a branch will look like, is it gonna look exactly like a from grown from seed or is it gonna look different?

This is a really easy to grow plant despite it's exotic look... handles southern California outdoor temps well and grows quite quickly into a nice, caudiciform medusa head plant. Great for pots as well as putting in the ground. Handles full sun, as well as performing pretty well as a house plant (though needs bright light, and still, it will get quite 'leggy'). And the great thing about it is it's cheap and easy to find (nearly all garden outlet stores will have this plant, now and then, at least). Easy to handle and 'branches' pretty bendable and sturdy, so exposure to sap not that big a deal. Still, avoid breaking 'arms' and then rubbing sap in your eyes, or you will be sorry.

Noticed this plant mysteriously showing up in the planter boxes where it didn't exist before... read more

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