Very interesting! Thanks for sharing! Any chance of one of them developing the other characteristics later when they get older?

Here in Brazil summer is hot and wet. Although my cacti are protected from the rain, I water them regularly on summer.
To tell you the truth, I never noticed any cacti in summer dormancy (but this may be just lack of observation from me)

I'm wondering how well H2O2 works on fungi and mold. I've had a ton of problems with seedlings getting afflicted with all different types of fungus and mold over the last few years. I tried many different remedies, including 3% H2O2. I can confidently say that H2O2 had absolutely zero effect on any...

G'day mmcavall, Thanks for posting your photo. It is not orange but I can see a different colour on the bottom of flower. I think the colour of petals are also slightly different from a standard asterias. Frank Thank you Frank. Indeed it have a different color in the bottom of the flower. I will tr...

Thank you very much Frank
I understood what you mean. I agree they are not hybrids group 1 X group 2.

Here is a picture of the asterias that do not have red throat:

If you make an Astrophytum hybrid, you should consider following two groups. Group 1: asterias, coahuilense, capricorne, senile (yellow petals and orange throat) Group 2: myriostigma, ornatum ( yellow petals only) What does it means when a supposed asterias or capricorne do not display an orange th...

Maybe as a safeguard you should cut two or three healthy, big branches and try to re-root them. Just one idea .

Thank you very much, Frank!

Thank you very much, Frank Fully understand about onzuka and fukuryu I want to be sure about the impossibility of asterias receiving pollen for other plants so if you dont mind I would like to ask again in a different way: Consider I have 3 plants: A : pure asterias B: pure capricorne C: hybrid F1 a...

Onzua and fukuryu are group 2. Hybrid, myriostigma x asterias is difficult to keep. Asterias can not receive pollen of any other Astrophytum species. Asterias can be a pollen supplier only. I have 1st and 2nd filial hybrids, HakuranSupers. Frank That is very interesting and important, Frank, thanks...

Thanks a lot Frank, Dave and Lucy.
I had already seen this book but it is too expensive for me...maybe someday. Thank you all

By "hybrid" you mean crossed with another species ? Which one would it be? Is it possible to know? Ornatum? Asterias? Your plant is most likely cross between A. asterias "Superkabuto" and A. coahuilense . I sowed a batch of seeds of that particular hybrid couple of years ago, an...

Thank you Dave!

It is a myriostigma It's a hybrid 100% and I would say 99% of the cultivars we see are hybrids of one kind or another. The best you can call it is.....''Astrophytum hybrid'' Thank you Mike. By "hybrid" you mean crossed with another species ? Which one would it be? Is it possible to know? ...

Astrophytuns receive japanese names according to traits they present, such as "kikko", "onzuka", "fukuryu" etc. I would like to learn more about that. Is there any web site were I could find this kind of information? Also, do we have here in the forum a thread to identi...
