Which trichocerus am I?

Thank you! I’m excited. I just looked up your suggested is and now I’m even more excited!! One day I want to come across a terscheckii also. Would make a great centerpiece somewhere. 
 

I need to get a few agaves for sure! I want some little ones in my pre-existing rocks, definitely. Larger ones when I start removing sections of grass. 
Is that a different variety than a ‘regular’ Agave utahensis? I ask because I can get the latter easily. Grab one when a raw desert lot goes up for construction haha. 

If you don't mind starting small, Aridlands Greenhouses in Tucson has Tricho. terscheks. available atm in various sizes. Also, if you find yourself passing thru town in the next couple months, say on a trip to obtain some palms, several plant sales both here and in Tucson this month.  Central AZ Cactus/ Succulent Society holds their annual sale at Desert Botanical in April.  Someone always brings bigger sized terscheks. to the sale, among all sorts of other stuff.

I myself like the smaller sized Agave more than most of the big boys.. Lots of choices also inc. species like  Agave toumeyana,  A. t. var. bella, A. polianthiflora, nickelsiae, victoria reginae ..and much prized Agave albopilosa. No doubt i'm missing several more sp. that stay at relatively smaller size.  The eborispina form of Agave utahensis is one of the most attractive Agave out there.. Somewhat tough to grow nicely here in the low desert though.

Someone I cleared all of your quote but the bit below, and can’t redo it.

Good to know, thanks! I am taking a mini vacation to Death Valley in the next couple weeks, so I am going to check at Cactus Joes in Vegas whole coming home. There’s a massive specimen in town I posted a while back, but I cannot recall where. I’ve wanted one since then. I don’t mind started small, I understand that the terscheks grow pretty rapidly once established (by cactus standards). 
 

I may pass through at some point to get me a Mule. So I can’t start a little larger than mail order size. 
 

thanks! I’ll look into the agave more. I would love some rarer variety’s than locally available. I have always that they were cool.

No worries..

Yes, from what i have heard they're pretty steady once they get going.  Think the biggest one i've seen locally is in Desert Botanical's collection. Don't doubt there are others around but obviously Saguaro are the most common large cactus in most peoples landscapes here. Aridlands has numerous other Trichocereus sp. among all the cacti they specialize in / sell also.

As far as Agave, agree.. like the rarer stuff over what you might see in everyone elses yard.. Waiting to hear word of the Botanical garden offering offsets or seedlings of a certain sp. from Baja.. Kind of big, but not huge ..Color is very silvery blue and won't draw blood when trimming off deal leaves ( has no marginal teeth along the leaf margins ) Can think of all sorts of things it would contrast nicely.  Have heard a few people have been growing it, but still really hard to find.

Here's a somewhat blurry  pic of Agave albopilosa, another species high on everyones  " looking for 2 or 3 " list.  Not cheap to obtain, especially anything bigger than seedling size, but worth it.
Has been becoming a little more easy to find lately. Supposedly cold hardy to the mid teens.

Nice choices. That one is definitely a Trichocereus and is big enough that it should throw a flower or two, and probably start producing offsets this year. From the looks of it, at least until it flowers, looks like an Argentine Giant ( Echinopsis/Trichocereus candicans ) to my eye. Now you need to find a pair of Agave utahensis var. eborispina for the desert garden:drool:

Agree that looks like Candicans...  Nice!

Here it is for size so you can see how small it is.
No juul discussion please, just something small I had on my person at the time.

Nice.. Looks like one of the Tricho. " Grandiflora " hybrids that are often mass marketed, but left un named..  Your other one budding yet?

Thank you! I think you are correct. 
the other Trich doesn’t have any obvious signs. The opuntia is getting close, however. The potted Cereus is in the beginning stages of one.

Ok sorry to bump this thread but I went by the Veterinarian’s office withe the Cactus garden in Waco TX to see what kind of damage -1 F freeze will do to a cactus collection. Here is what I saw.  Appears that the low growing cacti were covered but the larger upright columnar cacti may not have been.  Notice the talk cacti are no longer tall!

@RyManUtah  I do have a small Joshua tree that I started from seed.  Maybe a foot and half tall now.  Other Yuccas too that were seed started.  I had an ocotillo but it finally gave out after several years of languishing.  There are several Dasylirions that are doing well,  a ponytail palm that tolerates but does not flourish due to the occasional hard freeze.   I do occasionally cover the ponytail palm. Most of these specimens are not readily available around my neck of the woods.  So some are bought online and others are seed raised.

not intending to divert from the original post but I have some pics of a local veterinarian's office.  He is apparently a cacti/succulent lover and has put in and nurtured an awesome cacti bed for these parts.  I know that it has been there for nearly 20 years from my sightings.  He used to cover the columnar cacti and had pipe supports built into the ground but I think the ocotillo has gotten so tall that he can no longer cover the tall stuff.  Anyway look at the pics and ID what you can.  Zoom in and look at what all is there.  Draw some inspiration from them.  I think that it is a fantastic cacti bed for a borderline 8a/8b zone.  One pic is from the median of the street.  The columnar cacti are at least 8-10 ft and the ocotillo is about 15 ft.

Wow, the Trichocereus Terscheckii, and looks like (1) Neobuxbaumia Polylopha took some heavy heavy damage. I guess the combination of wet soil prior, then ice, then extreme long duration low temperatures were too much. I know of a few Terscheckii south of Austin that with a little protection came out unscathed. Neobuxbaumia came out mostly undamaged from areas that saw 5*F or warmer.

Saguaro I would expect to die at those temperatures and duration

What I’ve been shocked to see is Echinocactus Grusonii(yellow barrel) through out the hill country have come out a winner. My neighbor left his out completely exposed to 2 nights of 3-4*F and from 20 feet away they look intact. I’ve seen others and the huge one(and smaller) above looks mostly undamaged. Great info. I’m going to repost your photos as a hardiness reference on another site?

Thanks for this update Jimmy. Amazingly the beautiful large echinocactus grusonii (and a smaller one) survived all the columnar cacti, some of which (trichocereus) are supposed to be much hardier. 

Are there more examples of barrel cacti surviving the winter of 2021? It would seem these are pretty wet/cold tolerant.

Thanks for the aid Axel.  I did finally find the old link.  I bet there are some barrel cacti that survived in other areas but this is the only one I know of around me.

This is a picture from the well known videa on the damage in Las Cruces after -5f. The presenter contemplates on the survival chances of the large golden barrel. It is damaged but might have survived. Size seems very important as other smaller ones in the area were completely flat after the event.

" Mesh " .. is probably shade cloth to protect the plants from extreme heat, vs wildlife. ( Not many things will munch on cacti, real' spiny ones esp., even during an intense drought ) . Many people do exactly the same thing -for exactly the same reason-  here during summer.  ..Otherwise, if it X cactus sp is  full sun-sensitive,  you end up w/ fried cacti ..In some cases, even using  cloth doesn't help protect them from damage.

I have several grusonii’s planted out. After weeks of rain the top of a small one collapsed. No cold or frost, just continuous rain for weeks. I took it out to see what will happen potted up inside.

Axel that golden barrel appears to have rotted from too much water too long.  I have found that too much water and cooler temperatures, or freezes will doom many cacti.  Golden barrel and Saguaro have both suffered in my garden due to cool/cold and wet winters.  Some of the Arizona crew could give us the info on these cacti for clarity.  There is a small chance for your cacti. Keep it dry, clean out rotten tissue, and treat it with an antfungal.  I know how you feel.  I have been in those shoes!

Thanks Jimmy, it’s not completely unexpected though as we have very wet fall and winters. I will use this experience to analyse what exactly happens to barrels in a wet cool climate. My other barrels are fine so far.

So the soft top, where the flowers develop once it is much bigger, seems to go first. As far as i can see this is their weak spot. I took a picture of the roots that look fine to me.

Looking at it, can say soil mix it was grown in is big part of the issue of why it rotted... too much water holding organics. looks like a lot of peat Moss in this case.. Probably the worst stuff cacti can be grown in.  Have had the same " Rot from the inside ..bottom to top " -usually-  issues with some of mine when i left in such a mix.  Rinse off all that muck and you'll likely see where the rot started.

Gold Barrels are grown in such far flung places as near coastal / coastal California where they can experience frequent rain all winter / fog drip all summer,  and in gardens here where they might get dusted with snow once or twice during the winter, on top of whatever rainfall they're also getting during a " wet "  ...and cool.. winter..

Whenever i pick up cacti from a standard nursery, they are immediately bare rooted / freed from the typically inferior soil mix most non - Cacti specialist pot their stock in, and replanted into a proper mix, IE: one that is at least 80% inorganics, adjusted only by what the particular species / genera likes more ( certain Echinocereus, Mamms, etc that want a more Limestone - based mix, vs. others which want more a acidic mix .. Those go in a mix that is more Granite / Volcanics- based.

Regardless, organic content of the total soil mix is less than 20%.  I still loose a few things here and there,  but, any losses are far less and usually due to some other error in judgment  i've made ( not watering enough / a little too much / too little sun ).

Would try again, only repotting them into a better mix after purchasing next time..

Thanks, i will rince the rootball and report back. One thing that puzzles me is why the Ruth Bancroft garden cover their barrels in plastic while at the same time they have so much experience in the correct soil mix and mounted planting positions.

 :greenthumb:  My assumption ..and it is just that.. is they cover their specimens because up there, you can see nights where it can get down to.. / below  freezing right after several days of soaking rain, which can cause freeze- related damage  ..so, by covering,  they're hoping to minimalize the potential for any damage to the surface of their specimens on such nights ..Again, just a guess, partially based on growing up in the Bay Area and experiencing many winters there..  I'd imagine the soil below the covered plants is cool ..but perhaps drier,  which can help thwart potential root rot issues. 

Huntington rarely gets below freezing, so their Gold Barrel collection might not face the same weather - related threat, ..all that often anyway  even if the cacti are grown in almost the same exact soil mix and both areas see extended rainy spells, particularly during a wet winter.

Generally speaking, folks down there can easily grow Uncarina.. a really awesome group of small, succulent -trunked trees from Madagascar. The Los Angeles Arboretum has some incredible specimens that have been grown there..for quite sometime, w/ out much issue, even during the wetter / cooler winters..

Same group of plants can be a little more challenging -but not impossible- to grow up in the Bay Area, mainly because it is cooler/ wetter -usually, lol- up there than down south.  Anyway..

Here, where these cacti are grown, where they can get dusted by snow every year/ few years ..Boyce Thompson for example,  a good %' age of moisture contained in the snow sublimates as it melts, rather than most of that moisture getting into the ground, so, while the plants may have been covered in a 1/3" -1" layer of snow for a few hours on X night in January,  when that snow melts, only so much of the runoff actually soaks into the soil ...say just enough to provide a drink, ..but not overly- saturate the root zone ...too much of which could encourage an environment for root rotting soil bacteria to thrive.

Boyce Thompson also sits in zone 9B, ..so it really doesn't get all that cold there to begin with.  A few miles further up the road at Oak Flat ( have shared many pictures of cacti/ etc succulent- type things growing up there here ) , you're in 8B /  very minimal 9A, ...so, a Gold Barrel growing in a yard there or in Globe ( Min.  9A ) may be more vulnerable to frost / freeze damage..

  This is how pretty much every native cacti growing up in the mountains here / elsewhere outside frost free areas  survives being covered ..or buried in snow at times during the winter.  Stems of some Cacti ( Certain Echinocereus for example )  " deflate " ( Shed a certain % of the moisture they contain )  as the plants take a nap during the coldest months as well.  A few things i have have to be allowed to " shrink " a little during the winter or they won't flower / flower as well the following spring.

The rocky, lifeless- looking soil they're growing in may look awful to our eye, but, for most Cacti ..and most other succulent-type things, ..it is perfect.  

That said, i see plenty of cactus specimens that ..for one reason or another ( usually heat and / drought stress related ) are nothing but clumps of stinky or dried out spine covered dead things out in the desert.



As for the roots of the plant, i can see where some of the tips are / had started  to rot.. I'd bet some of the bigger roots will easily break apart if you try to rub the outer cover off.. regardless, have had plants do the same thing ..roots look " ok " when soil is washed off,  but the plant itself is rotting, from the inside out.. 

Can't remember exactly what it was but 99% sure i had something do exactly the same thing a few years ago... Outside of the plant looked good, until i noticed a softer looking spot developing on the stem.. at some point, i opened up the plant to find the entire interior " core " of the plant was rotted, leaving just a still alive outer  " shell " ...which was also slowly -but surely- rotting away ...kind of like a Pumpkin.  You hate to see it, but,   things happen..

Thanks so much for the valuable information. I know the combination of wet and cold is generally considered to be the main factor and that is why i decided to analyse the damage on this little grusonii since it only received copious amounts of rain and no cold. For the moment the lower part of the barrel shows no weak spot and the roots seem ok. So for this specimen in this particular climate it would seem that the top part suffered the most damage in the early stage of fall and winter. It will be interesting to see whether my other barrels, bigger in size and in better locations, do any better.
