RE: what is this

Looks like a dogtail cactus to me. I have one on my covered patio and it receives bright/high light (only some direct morning sun) and is doing quite well. I only water when its completely dry which is once every week and a half or so in FL summers and only every Month or so in our winter.

RE: what is this

Looks like Selenicereus testudo to me...I bought one not too long ago from a big box store that's from exotic angels that has it tagged very wrong, they are calling it something else... forgot what.

RE: what is this


It has some of the largest flowers in the cactus family.


That's Deamia testudo, what I had thought was a monotypic genus.

RE: what is this

Jeff, this one used to be Deamia, now it is just another Sleenicereus.

sjbaby, by whatever name, it is not a really good houseplant. Growth is vigorous, spines are nasty, flowers are almost unheard of grown indoors. I kept one for years, let it sprawl across the windows, allowed it to crowd out other plants. Nary a flower. It is an easy, forgiving plant. Watch for spider mites. Good luck with yours.

RE: what is this

i can summer it out doors, but the spines must get worse right now they are just kinda fuzzy, thank you for the info.
