Setiechinopsis mirabilis ..... and quite a few questions
Lots of questions started to flood my mind.
It had been a dull day, the flower began to open sooner than I’d expected. Did my transfer from bright(ish) GH to house initiate the flowering process?
Previously, my Setiechinopsis lighting had been a different setup, because of technical issues. Was it the light intensity or colour temperature of the light which caused the plant to stop and restart?
Does the plant need very low light intensity to flower, because it struggled to flower with the new jig, but the old dimmer light later in the video process of last time allowed the flower to fully open?
And so my thoughts continued.
I thought (and still think) the adjacent bud will abort, but I am not so sure in the light of the new day. I may have the opportunity for further investigation this evening/weekend.
Recollection of filming Rebutia, and observation of Gymnocalycium earlier in the year with its poor weather records, lends further credence to light intensity AND temperature as initiators of flowering.
Further thoughts from forum members before 6pm would be much appreciated.
Regardless ............ enjoy the video.

Re: Setiechinopsis mirabilis ..... and quite a few questions
I'd hurry, it's a very short-lived plant, once they've flowered, usually in the second year from seed, they've done all they need and don't make it to the next year. There is a theory that cutting off the flowers might keep the plant alive longer.

Re: Setiechinopsis mirabilis ..... and quite a few questions
I've heard this said by many, and seen it mentioned in books too. Has anybody done any kind of research on this in habitat? My experience with them is that they can easily live for 10 years with regular flowering. My oldest was 15 years old before it died, but I suspect a cold snap killed it, not old age.

Re: Setiechinopsis mirabilis ..... and quite a few questions
I find it short lived. I've grown it 3 or 4 times, but I have never managed to keep it more than a few years (under 5). It seems to put all its energy into flowering and setting seed. The way I grow it at least, its perhaps as near as we get to a biennial in cacti!

Re: Setiechinopsis mirabilis ..... and quite a few questions
Here are mine, photographed just a few minutes ago. One was grafted onto Opuntia humifusa (the left one, I think) though the stock may have died and the scion rooted - it's happened with many of the grafts I did when I used that stock. They were grown from seed sown in January 2009. As cacti go, I suspect they are short-lived but not very short-lived. Rather, they quickly become very scruffy and reach a point that most people would dispose of them.

Re: Setiechinopsis mirabilis ..... and quite a few questions
My first Setiechinopsis was about 15 years old when it died. As it’s propagated exclusively from seed and self pollinates perhaps there are longer lived seed strains.
Re: Setiechinopsis mirabilis ..... and quite a few questions
Hello,
perhaps this story that Roberto Kiesling told us explains the questions around Setiechinopsis mirabilis:
The plants usually grow in slightly saline soil. When it rains heavily, the salt is washed into the lower layers, the seeds germinate and the plants grow, flower and produce vast quantities of seeds. Slowly, the salt rises from the lower layers back up to the surface. The conditions become hostile for Setiechinopsis mirabilis. The plants slowly die - until the next heavy rain. An event that occurs approximately every three to four years.
A story - but perhaps with a true background.
Kind regards
Nobby
