FWIW, my observations on growing this extraordinary species (largest seed in the genus, and with no known close relatives), are as follows: This is the most cold sensitive species of Mam. that I've ever grown. Below 25° F, they can be damaged. The only other species that I'm aware of that's this sen...

Nice pic it's most likely a https://cactiguide.com/cactus/?genus=Mammillaria&species=microhelia What I inferred from the CactiGuide description of M. microhelia is that the variant microheliopsis has pink-striped blossoms like mine. That opinion has been the subject of debate for decades. Some ...

Pediocactus and Sclerocactus would probably benefit. Opuntioid seeds would be good candidates too. I've read at least twice that Echinocactus [/i] and Homalocephala [/i] are easier to coax into germination by using it as a means of scarification prior to applying water (soaking in acid overnight). ...

One interesting species of Hesperoyucca is worth searching for in that area https://www.inaturalist.org/taxa/537787 ... -newberryi

Good web site. Are Sclerocactus found near Las Vegas?

loyall, I have seen specimens for sale under the name Mammillaria pseudoperbella (synonym for M. perbella ) that looked exactly like your plant. So, I agree with your initial guess. Thank you Nino_G for that feedback. So perhaps I was correct. I'll just wait to see how it develops and blossoms. Bef...

Thus far I haven't started any from my last order. I almost always get a great percentage of their seed to sprout (unlike many other seed vendors). In a month or 2, they will strike out the seed which is sold out. That's a good time to place an order.

Since almost all of my seedlings are in a dormant state until Spring, I'll try to remember to post some images of the species I mentioned. I like your approach to the use of beneficial organisms, and I too am starting to employ a similar strategy. It sounds like a logical method to use for the more ...

In the meantime, I'll search for your conclusion to see if it's available, and if it looks similar.

Noel. May Santa stuff your stockings with rare C&S seed packets. A happy, and prosperous new year to one and all.

I try to follow a lot of these Zoom talks and think (besides this) BCSS does a great job. Were these also held before the pandemic? Regarding the lecture of Rob Stevenson, I must say it's confusing. According to Llifle, Turbinicarpus pseudomacrochele is the accepted scientific name, but the Interna...

Any special treatment for; Maihueniopsis mandragora Pterocactus araucanus Pterocactus megliolii Puna bonnieae Toumeya papyrancantha [/i] ? I've just sown some Pterocactus seeds from Elisabeth & Norbert Sarnes (P. australis & P. fischeri). I sterilized the seeds with a hydrogen peroxide solu...
