p.s: Escobaria vivipara was NEVER! included in the genus Neobesseya.

Escobaria is a lovely plant, and is so variable. This has given rise to all the names which Punker has listed. It can be found from Arizona (and probably into Mexico) right up into Canada.
I think the form known as v. bisbeeana is one of the nicest, as it has really stout white spines. In all forms the flowers tend to be similar, which is one of the main reasons for their combination.
Neobesseya contained 13 species at one time (Britton and Rose), which have all now been merged with other genera. It had become a lumping ground for some relatively difficult to categorise plants, but as more commonalities became understood, so the differences seemed less significant.

Hy Chris!

I agree with you

Happy new year to you and to everyone on Mammillaria forum

Hi cacti lovers!

This plant should be hardy at least up to -35 C, but it depends on the stock origin. Even not covered with much snow, it is from dry locations. Has to be already compressed and dehydrated when cold begins, in November typically.

This is my photo from a native location in Southern Alberta, Canada. I also transferred some plants into my back yard last year.

And some more photos of the same species at another location in Alberta. All were fond at sloped eroded hills around rivers.



Please mention two small seedlings above the big plant at the second picture.

Welcome to the Forum, and it is great to see some more Escobarias!

I've just been out to give a talk about plants I have seen in Southern Arizona, and I had seen a number of forms of E. vivpara, so slides of these were part of the talk.

I did know they grew in Canada, but have never seen photos of them - truly a species that defies all rules, with regard to distribution and hardiness.

Wonderful!

One more photo. Wintering of E. vivipara, one of my outdoor plants. Well, it is still deep winter here in Calgary. Will be no signs of growth or expending until May.

Hello all,

Your plants look awesome punker and agrippa!
Seeing photos of them growing in the wild in Canada is really a privilege- thanks.

Cheers,
Laszlo

Hello,

Today two of my Escobarias finally emerged from under the melting snow (this winter they were covered by 50 cms of snow but before that they endured quite a few cold rainfalls in December and even January).
Here is what they look like.

and Escobaria vivipara var bisbeeana

I am thrilled to see them doing well.

It is amazing to see the v. bisbeeana in such conditions and doing well, considering it lives in Southern Arizona.
