The tallest I have now is only 1ft. The tallest I had was 4-5ft but I had to cut it down. In a pot of course, it doesn't tolerate freezing at all (Opuntia brasiliensis).

   There certainly are a plethora of glochids!  Exactly not my style.

Glochid removal kits are pretty much essential.

My tallest Opuntia at this time is a form  of Opuntia phaeacantha (possibly var. engelmannii) it gets very large pads and stands about 3' (.9m)tall.





My tallest Cylindropuntia is Cylindropuntia kleiniae at 6.5'  (2m)

I grow a couple of Grusonia. Grusonia aggeria, and Grusonia clavata (clone one). Clavata is very hardy, whereas aggeria is susceptible to damage from icy snow cover.

Some very handsome plants.  The straight spines on Grusonia clavata remind me of short porcupine quills (without the barbs). 

The second "group" pic with Grusonia clavata is really surreal: the cactus looks giant against the lewisia, and lavender flower (Erigeron?) look giant against the cactus!

Ya I like this one. A bugs eye view! The Erigeron is compositus.

Agree! Would love to have that motif in my own garden Shocked

I also liked the Cylindropuntia!

Trond, cylindropuntias are the tall cacti for our climate. In the unheated greenhouse I have had them to 180 cm.

That might be a good cactus for over there.  I know Cylindropuntia imbricata can handle wet feet here in the winter.  I bet if it was high on a mound it would do ok, and if it had some heat for growth in the summer. Smiley

Opuntia chlorotica is an upright shrubby Opuntia from the Mohave and Sonoran deserts. I have been able to grow it in my Garden with no apparent damage for four years now. It is planted about two foot away from my south foundation. This extra warm micro-climate allows it thrive.

John, that is great that you can grow O. chlorotica without protection.  I have tried a few, but they don't like to live past 5f.
How long have had your?

The challenge for the plants are not the winters, its the cool summers. They simply like it warmer during their growth periode than what we can expect here...

Anybody knowing the name of these Cacti found on the small island of El Gran Roque (Los Roques archipelago) last summer?

The first one is a Melocactus I believe:

   



The second is an Opuntia:

   



The third is completely unknown:
