Getting opuntioids to germinate is a challenge - often. I have thoug had succes with most generas but have always failed with the genus Miquelopuntia. Now I got my hands in a number of locality seeds of this spiny gem. Anyone on this list have had succes with the species and knows how to convince th...

My experience: darwinii - 21C dry, -16C outside unprotected but then slowly dying over a few years. platyacantha - 21C dry ovata - 18C so far. mandragora - 8C so far and not looking good. And other south americans. Aus verschaffeldtii -18c so far, -15C outside, dry, close to the wall. Pterocactus, a...

Cool, bright and dry. I keep mine betwin -10C and +5C. Dry, first wartering in late March/early April.

Hej Gerlot My mother use to have one of these, she started it all over every 3th year as she had it in her windowstill. She would also cut off the huge spine that it developes along the main stem when we were small kids. I had one my own but got rit of it when I got my own children some years ago. B...

Lithops lives other places than Namibia. And the sentence should read: 'Just because they dont get frost in winter in their naturel habitat, doesnt mean that they cannot tolerate frost'! We have examples of alpine mesembs that maybe gets -10C in RSA but survives a winter in Ontario with a lot colder...

The genus Opuntia is the solution!

Martin

Yes, there are lots of Lithops and lots of other mesembs that can tolerate a dry -10C. Especially the species from inland locations.

If you want to start them start with seeds. Go for species like lesliei, julii, karasmontana for a start. You will find lots and lots of local forms.

Martin

For at least -18C: Echinocereus reichenbachii Echinocereus davisii Echinocereus triglochidiatus Echinocereus subinermis Escobaria roseana Escobaria minima Escobaria vivipara Escobaria missouriensis Escobaria dasyacantha Escobaria albicolumnaris The rest I dont have in my collection and have not test...

There is no valid subspecies called cordata.

This is certainly about love to its owner! You have a perfect plant!
(Who said that plants dont have feelings?)
Martin

the species is easy on its own roots. I keep mine in large claypots in sand/gravel mixture and water them a lot like most other opuntioids. In winter safe to dry -10C. Martin Übersetzt von Sammy/Translated by Sammy: Die Art wächst sehr leicht Wurzelecht. Ich halte meine Pflanzen in großen Töpfen in ...

Very nice one, hope my specimen will flower next year. Maybe I can try crosspollinate it with my various verschaffeltii clones. Martin Übersetzt von Sammy/Translated by Sammy: Sehr schöne Pflanze, ich hoffe, mein Exemplar wird im nächsten Jahr blühen. Vielleicht kann ich versuchen eine Kreuzbestäubu...

Not 50 species, 50 species AND local variations. My best bet is still whipplei because it is very shrubby and the fruits are placed in a similar way as on one of my larger whippleis. It is not imbricata, I am certain of that.Identifying opuntioids from pictures are a difficult task and the more plan...

I have around 50 species and localities of the genus Cylindropuntia in my collection. No, it is not a sub-genus, it is as valid a genus as any. Anyway, to be certain about its identity is not easy. These plants are very difficult to identity without seeing them in real life. My first impression thou...

I have kept Maihuenia poeppegii and Maihueniopsis darwinii outside for serverel years. Austrolebias verschaffeldtii survives close the the wall of the house. Inside the unheated greenhouse are serverel member of genus Maihueniopsis, Maihuenia, Pterocactus, Austrocactus, Opuntia penicilligera etc har...
