Most beautiful/rarest/etc cacti you have or had.

Used to 'attempt' to cultivate three Brazilian beauties back in the 1980's before plant importation was severely curtailed ; one positive attribute as they are all now threatened with extinction in habitat .
1 Uebelmannia pectinifera , desirable for its unique epidermal qualities resembling something reptilian . The comb-like (hence the specific epithet) spination
2 Discocactus horstii , a miniature of its genus , deliciously scented flowers and porcelain like spination .
3 Buiningia brevicylindrica , notable for its vertical yellow cephalium and yellow flowers .
These are examples of many species of cacti , mostly existing in isolated edaphic communties ; all are extremely vulnerable in habitat . Cultivation is very difficult , with very specific requisites .

 

Love seeing the photos and hearing about the rarities from Brazil! And @Fof 's garden bed surprised me - I thought Queensland was humid. In fact @Michael Hewett 's plants surprised me too - Wales is permanently damp. I have tried in the past, but my greenhouse is too crowded and the cacti would stab me as I tried to reach other plants!

 

@CarolineL what you need is a separate cacti house, like this guy.

 

Oh good grief @Logan - I'm barely coping as it is . I used to have 2 greenhouses and a polytunnel, and going down to 1 has helped. So don't start giving me ideas

 

Oh ok @CanadianLori enjoy what you have.

 

I'd like a place like that for my cacti @Logan

 

See @Logan - Michael is now planning

 

Common Echinopsis from Abbey Brook. Probably a hybrid. Flowers look better in real life than that photo.



A Rebutia. Common again but I like the flowers: flowers over a long period.

These cactus live outside all year around but have rain shelter.

 

Great pics, guys. Keep them coming.
Carolinel. The cactus bed was in my front garden, in the suburbs of Sydney. I had a block of land, in Qld., that I intended to retire to. That idea died a death, when the Qld gov decided to buy me, and a load of others, out as they wanted the coal we were sitting on, for the Tarong Power Station. Another government stuff-up, as it turned out they didn't need it. C'est la vie.
As for it being very humid, it could be, especially in Far North Qld., and around the coast. Where I was was perfect for a LOT of spp of C&S.
Apart from the Heurnia, it was very common to see ferel Agave, Opuntia, Yucca, & Hylocereus. My last, illegal, hike over my ex-block showed lots of Cereus peruvianus seedlings popping up, all over.
Agave americana, I think
Agave americana variegata
Agave angustifolia marginata, I think
Huernia zebrina + Opuntia spp
Hylocereus spp
Hylocereus spp
Opuntia spp

This one is the remains of an Opuntia, after a visit from the Cactoblastus moth.

As I said earlier, I got some seed of Setiechinopsis mirabilis.
7 out of 10, so far.

 

Good grief @Fof - that one making its way up the tree is amazing!

 

I've got one of them but not going up a tree obviously.

 

@Fof the climbing one, is it a dragon fruit?

 

Hi Logan
Yes it is. I have it catalogued as Hylocereus spp, but apparently is now Selenocereus spp.
The next photo is of it's flower.
I have just realised I didn't ID the pics.

Edit. Sort of IDed them

 

Fof, i thought that it might be a dragon fruit, this guy grows them but he's in Australia.
