I spent a while yesterday trying to find a photo online of a ripe Tephrocactus fruit but failed.

How old does a Tunilla have to be before it will flower?

Me too.

I am now very intrigued to know how the seeds get distributed.

They have floats attached to the seed so may be spread by floods? Do they get concentrated sulphuric acid floods regularly in South America? The recalcitrant inhibitors and woodiness must need a lot of weathering before they are removed sufficiently for germination. Does light destroy the inhibitors?

Well it all depends where and how they are grown I find. Maybe 5 years if given good light and a cool dry winter rest. Like a lot of clumping plants they grow exponentially so the first few years they seem slow but once they get to fill a 5” /6” pot they speed up and should be large enough to flower. Except there is a lot of variance between different clones and I have a few which hardly ever flower and one or two not at all....seed grown ones take a good bit longer.

Here are some Tunilla corrugata in 6cm pots in flower - lots of sunshine and being pot-bound encourage flowering, I find.

That is lovely Tony! My only tunilla is very floriferous but a pillar-box red flower. I must try to get more.

Great looking plant Tony
Pot bound ..... easy to achieve
Sunshine in Leeds ..... less easy to achieve
Time ..... err ... difficult

Cheating Tony they are not ‘in’ 6cm pots they just start out in one.......but you are right treating them mean gets them flowering. Mine are currently pleading for a little water but I tend to hold off until April as I find this encourages a display like this...

Airampoa/Tunilla flower like dandelions if you get the sunshine, see all the posts on this sub forum from last year when we had a very sunny April/ May. ( but no fruit )
