Good day to all! I have been wondering if O. monacantha can be used as a root stock for grafting. I have plenty of them in my yard. Have any of you tried it? Thanks in advance

Third looks like E. calochlora

Woah! So this is a Turbinicarpus Hopefully, more would ID this but I will stick to this. Really looks like it. Thank you

Please help me on this one. Tag was lost when I got this. Thanks in advanace.

Is this normal? It was green the other day.
Still rigid to touch, not soft. Sun exposure is about 4-5 hrs, hot and humid.
Thanks in advance
Note: First pic is the pic when I bought it. Had no recent pic of it when it was still green. Thanks

Thanks to you both for identifying

Is this an Echinopsis? It opened its flower last night. Please see pics. Thank you

Magdanag umaga! Coyphantha usually are solitary and looks like yours is pupping like crazy. I though maybe C. reduncispina except for that. I did not see the classic Coryphantha groove on the top of the tubercle, but that is no proof. You may just have to wait for flowers... Shmuel Thanks for the r...

How about the last photo? Which Mammillaria is it?

Do you happen to know the species, please?

Please help on the first three pics. Is this a Coryphantha or a Mammillaria. Also, the fourth pic is a Mammillaria but do not know the species. Thanks in advance

It just popped a seed pod/fruit

Thanks for the ID

Thank you. I have been confused for almost a year now. Say, what are the differences between the three species I have mentioned?

Help! It is confusing
