Hardiness depends on where you live

My Town home front yard in Tucson, Arizona:

"Cereus hildmannianus cultivar" .......... (sensu lato)



Trichocereus cultivar ..........


Most Mexican and Andean cereiod and globular cacti (and of course US south-western desert cacti/xerophytes) grow well as garden landscape plants here. I even grew some of my Brazilians in my font yard here - until last year's 17°F record low temp severely damaged my Coleocephalocereus aureus plants - I no longer grow them in my front yard during the winter. BTW, strangely enough (to me) my Discocactus placentiformis survived that cold spell completely unscathed!

Excellent! I have to figure out how to grow outside. I have lots of critters. Thanks for your posts.

Amazing that the Discocactus could support that... Could that C. peruvianus be a C. hildmannianus?

.......... Could that C. peruvianus be a C. hildmannianus?

Note the "Cereus peruvianus cultivar" in quotes - it could be just as well be "Cereus hildmannianus cultivar (hybrid)", but other enthusiasts seem to prefer the former epithet - hence (sensu lato). Actually, Brunãozinho, I prefer "Cereus hildmannianus cultivar" so I have changed it.

Just curious. Are your winters in Tuscon pretty much without rain?

You are so lucky, I wish I could have outdoor cactus.

There are a number of opuntia that are winter hardy.

That is true but they don't survive
Dutch winters .

Why not?
If it's due to a lot of rain, I live in an area where we have rainy winters also.
I could probably send you some..

Oh, yes, should be tens or cacti species that survive in Dutch climate outdoors. My Opuntia polyacantha does even in a pot, at below -30 C.



So does Escobaria vivipara in my back yard, both native to Canada. May be You should make a raised bed to drain the excessive moisture.
