Oh, Barb, does he ever look lonely..I'll try and find him a name...Euphorbia Meloformis(South Africa) grows, no more than 4-5" high...usually has ten ribs..good for us..I think we got it!!! Elaine
sorry, buts never a Euphorbia.
you cab test ityourself: if it's euphorbia, a little scracht, lose white milk!
it's an cactus: may a baby of melocactus?
Not a euphorbia..the spines on all euphorbias are in opposite pairs along the stems.Its a cactus,its echinocactus grandis.The shape and the color gives it away.
