I wonder if tetragonus shows a good deal of deviation in its appearance across its native range. I suspect these ones in the South Florida landscape were imported from Mexico or elsewhere, the ones I have seen in habitat in Everglades seem to have longer spines, different growth habit and stem appearance.
This mama was here when we moved in so I can't vouch for its specific origin, but I wouldn't be surprised since I have such a range in the babies of just this one! I need to make an Everglades trip to see them in habitat - any specific location you would recommend?
@@succulentschool There’s a big one in front of the ranger station of John Pennekamp, you can see some photos of it in Google Maps photos of the park. A good way to find locations in the wild is iNaturalist. I’d definitely try to find Harrisia fragrans in the same areas and maybe Pilosocereus robinii, but it looks like all the locations of those are obscured because of the endangerment level
I asked someone who grows only Florida native cacti commercially about the these landscape ones in S Florida, his response - "That's Acanthocereus subinermis which has been erroneously sold as A.tetragonus for decades. Not native and it gets out of hand pretty quickly." Some sources list subinermis as a synonym for tetragonus however. Location native range does seem to be limited to southern Mexico for subinermis so I'd say they are indeed a non Florida native lineage which some would consider a different species. Either way, I have both variants in my yard, and they're both pretty cactuses. Not sure about the getting out of hand quickly part, it is fast growing for a cactus and spreads from the roots but I've never seen it really invading.
@@stevemyers7876 I so appreciate this! Thank you! Now I'm even more excited to see the tetragonus in habitat! I'm having difficulty finding good information for subinermis - like you mention, it seems to be considered a synonym of tetragonus or there are very limited images. I'll keep researching but thank you, again, for pointing me in this direction. I love learning from other plant people. Similar to you, I am seeing fast growth but it has only spread from pieces that have fallen or cuttings. I haven't actually had any fruit either (after 2 summers) despite many, many flowers.
Hi! I'm glad you are interested in growing them! I can ship within the U.S. but I don't have any heat packs so I guess it would depend on where you live. Send me your mailing address and we can figure something out! Email is succulentschool@gmail.com 😊
Hello! Thanks for the question! I have found that they root very easily. I have made a few videos that might be helpful: th-cam.com/video/3B_4DAlYaH8/w-d-xo.html (this one is specifically about propagation by cutting) th-cam.com/video/c_8vQ1mzqAU/w-d-xo.html (this one is about repotting) th-cam.com/video/l62eQTOeLfM/w-d-xo.html (this one is about water propagation) Hope that helps! Let me know if you have any more questions!
Hi! Thank you for the question! Dragon fruit is Selenicereus undatus and this cactus is Acanthocereus. There are definitely some similarities in how they look, especially when they are babies but there are clear differences in the spine (thorn) size - both length and width - and the shape and number of the ribs (dragonfruit ribs have more pronounced waves). Hope that helps!
@@succulentschool Oh boy lol I love dragon fruit and was driving down the road amd someone cut one of these huge cactus so I brought some cuttings home about 3-4 feet long and put them large buckets of water and they are growing and rooting in the water.Thought I had dragon fruit. I guess I have some decisions to make lol Thank you for help and knowledge. Do they have any value?
@@rpfl5586 That's an exciting find! The blooms are pretty in the summer but they only last for one night. I haven't seen them sold in any stores but I'm sure people would want to buy them if you didn't want to plant a patch!
Wow Lovely cactus ^^

Thank you so much!! I'll definitely be going soon as it's only about 90 minutes from me :)

Could I purchase a flat rate box of barbed wire cactus cuttings from you?

I was gifted some cutting from a cactus that looks like this. How do I plant/ take care of them? Thank you in advance!
