Resin spurge is the hottest chemical, called resiniferatoxina, found in Morocco. Resiniferatoxin has a Scoville rating a thousand times hotter than pure capsaicin from hot peppers, or over 16 billion Scoville units!

This has proven to be a very cold hardy succulent Euphorbia. My plant has been in the ground 15 years & has survived temps down to 15 degrees with no problems. It has even been covered in snow! My garden is in Hesperia, CA at 3500 feet zone 8.

Mine is in its second year and has just been potted up in size. No problems with our rainy cool winters in a container. The color seems to change with lighting..sometimes a nice aquagreen with red spines. I did notice that even though it had completely covered a 6" pot in stems,when I knocked it out of it's pot..seemed to have a very fine root system. Like what you would find with fat plants that grow on rocks in habitat...none of that finger roots spilling out of drainholes like many succulents.

I like my first Moroccan Mound so much that I planted another today. It's great on it's own but groups well with my other succulents - it's structure is an interesting contrast.

It also ranks high in that the critters won't eat it!

The Euphorbia resinifera and the Euphorbia echinus are both endemic plants of Marocco. The E resinifera is more in the surroundings of Maracesch and the echinus is more in the surroundings of Agadir and Tiznit.

Though in some parts of the world (probably S Africa) this small rapidly suckering plant is considered a toxic weed. But in So Cal it just is a nice landscaping succulent, making an attractive colony of short, blue-green, 4 sided hardy little columns. I have seen some plantings where this plant covered many square yards of yard. Very commonly sold at garden outlet centers and is one of the easiest and carefree Euphorbias to grow in both pots and in the ground in southern California.
