what is a stick cactus?

I think Susan is referring to the all green version of Euphorbia tirucalli and the one that turns yellow/orange ('Firesticks').

Susan,
As far as I know, there's only the green cultivar and 'Firesticks.'

Planto

Hello Susan,
in addition to the green & the Firesticks cv, there is also a different species called Mahogany that has a dark, brown?/ sorry I am not real good with colors. This is not Euphorbia tirucalli but it is very similar in growth habit. There is also a variegated Stick cactus that has made an appearance here before, mine came from a friend in Florida, who got it from Thailand. I have also noticed a seller on ebay who has listed a green crested & a variegated crested Stick cactus, though I do not think the crested plants are actually Euphorbia tirucalli but another sp. So I guess the sum total would be 5 or 6 different ones, haha. Hope this helps. Rick

Thanks all!

These are Euphorbia tirucalli as Planto so generously supplied the name. They grow really well for me. I have (2) large green ones in my office and (2) at home, one of which is a firesticks and it is a beauty. I received it from Accents from Home and Garden last week.

Thanks for the new information, Rick (Trickster). But like you, I don't think I would like the crested ones.
