Euphorbia milii :o) It is native to Madagascar ...

Thank you for that Hywel, she tells me it has big thorns!! Didn't know Euphorbia had thorns like that!!

Euphorbia can have vicious thorns!

Is it suited to the outdoors in the British Isles?

RHS Seems to think so…

Hi, I always thought that this needed a minimumwinter temperature of 54 deg f, you live and learn, Derek.

Me too Derek which is why I checked after Bulba queried...

Thanks to everyone for all the information.
I have passed it all on to my friend. (Query solved!) :))

This is another reason why I love this site, amazing what you can learn. Thanks Bulba and Moongrower great the knowledge you pass on. I thought they were only houseplants too. :O)

We'll that one is a bit thorny for a houseplant... It is supposedly the crown of thorns worn by Jesus.

Hi Mg, just looked at the website you gave, it says H 1.b, which is 50 to 59 deg f or 10 to 15 c, and can be grown outdoors in summer in warm / sunny and sheltered locations, ultimate height 0.5 to 1m. Ultimate spread 0.1 to 0.5m, in 10 to 20 years, I think you must have misread it Mg, Derek.

Possibly computer away being sorted and am not used to iPad

Hi Mg, it confirms what we first thought though, proves we're not losing our marbles. :-) , Derek.

Lol!
