Electric

[RAYWOODBRIDGE]

Contrary to rumours I have not been giving this Tephrocactus articulatus fma pediophilus the electric shock treatment, just wondering when to repot it.
It is sending two new segments up from the base and it will be interesting to see how they get through that lot.

Interesting and quite different to the clone I grow. Where did you acquire it?

[rodsmith]

Not only when to repot it but how to repot it.

[Tony R]

Super spines!
I have a number of different clones of this too.
Should be called Tephrocactus aoracanthus, quite distinct from articulatus really.
Good luck with the repotting!
Yes, some clones clump in the wild - up to 1 m tall and 3 m wide - you will need a big pot, Ray!

Here is my assortment of T. aoracanthus, ready for repotting too! The one on the back left has had two flowers each of the last two years, but no signs this year.

[Mike P]

One of mine has a bud but it produced one last year and aborted it before it opened annoyingly.

Tony;
That's a great group of plants, pity they do seem hard to flower even on a good year like this one, the plant in your photo which is front right and has straight dark spines is what I would call aoracanthus and I have a plant that looks just the same, but the other four I would say look more like the form Ritter called Opuntia pediophila also called Opuntia hossei but I cannot remember where that name came from, I just have my plants labelled T. pediophiilus but as you say they are now within aoracanthus , James Iliff had it as an ssp. thereof, apparently the flowers which I have not seen are very similar to T bonniae which we have been talking about in another thread.

Mike P;
I got it from Micheal Kiessling as a 30mm one segment unrooted cutting back in March 2015 under his reference MK 433

Tony; Thank you for that beautiful photo of the flower on pediophilus, I love the different colours on the new segments so Tephrocactus.
