Just a view of a native sardinian plant: Euphorbia caracias. The pic was taken this afternoon. You can see also an Agave and an Almond tree.

RE: Euphorbia caracias

Nice plant, Davide.

Do you know of which subspecies it is?
There are E. characias (spelling!) ssp. characias with dark brown and ssp. wulfenii with yellow nectar glands. Both may occur in Sardinia.

Thanks Frank. Sorry I don't know which subspecies it is. I have tried to google E. characias wulfenii and I found a lot of pics (all seem close to my plant) but no sites for E. characias ssp characias. Is it different from E.characias?
