Cactus spines: more than just a bloody nuisance

- This video is all about the incredible cactus spine -- an organ that serves not only as a form of protection, but has evolved to enable these amazing plants to live in some of the most inhospitable regions of Earth. I examine several different cacti species, including Browningia hertlingiana, Pachycereus pringlei, Copiapoa gigantea, Oreocereus celsianus and the jumping cholla, Cylindropuntia fulgida and the unique evolutionary advantages afforded to them by their spines.

Fascinating! Isn't it amazing how plants adapt to survive
One of my favourite things to geek out about!
Love these videos youre making
Appreciate it!
The title alone make me watch and i knew you'd be an Aussie or a Brit 😊 Subscribed.
Thank you 🙏
Some cactus spines dont hurt, some hurt a little and some really bloody hurt
Pretty much sums it up! 🤘
Very interesting information. coool
Thanks!
Your videos are on point. 😊
Appreciate it!
i would love a jumping choler, everything in WA is soo much harder to get cause of flora/fauna quarantine laws its also interesting to see how the different shapes and spines do matter for they're individual needs
Yeah I’m only too familiar with the quarantine laws for WA - wish I could ship plants over there more easily.
Awesome vid and you showed some beautiful cacti!
Thank you, glad you enjoyed it
Another banger vid thanks
Thanks! Appreciate it
im loving this.
Thanks 🙏
great video has always
Thanks, appreciate it!
I love your videos, they are always so interesting…I had never seen a cactus like the Pachycereus pringlei loose it’s spines and callous over, amazing. Are there any other cacti that do that? Does the callous serve any further purpose? Tropical plant shirt contrast with arid cacti nice. 🌵🌴
I’m by no means an expert on all the huge cacti species, but you see a similar phenomenon in the Saguaro - huge spines on seedlings, becoming much reduced in maturity.
As far as the callous - I’m not quite sure if that’s what it is. They don’t necessarily lose their spines as such, moreso that new growth in mature stems don’t produce spines (or they produce much reduced spines.) Someone better versed in these species might be able to chime in about the nature of these scars and whether they serve a purpose because it’s not something I know unfortunately!
Excellent! thanks
Thanks, appreciate it!
Some of the worst cacti spines I have encountered were on Opuntia species when I was a kid. They were like fibreglass if you were unlucky enough to get a handfull. They were so fine they were almost like a powder. I pushed my sister into an old Christ Thorn plant (Euphorbia milii) when we were young & she was still getting thorns out 2-3 years later. I got the strap!
I’ve had some of those Opuntia spines in me and you’re not wrong - it’s unpleasant! So many horrid shards that are almost invisible. I generally stay away from cultivating Opuntias and the like these days to avoid the hassle.
Opuntia is forbidden in my apt. and garden. No exceptions. ☠️
Great video as ever! Isn't there another reason which is to reduce transpiration?
Yes definitely, especially in species with very dense spination.
Keep it up man!
Thanks!
I used to graft on Pereskiopsis, maybe the most evul plant i have come across. You dont feel much when the glochids go in your fingers, but after a week or two, you will have puss filled blisters, deep in your fingers, and you can only cut them out. I try now with selenicereus grandiflorus instead, and i keep my fingers puss free ^^ Regards mate!
Yeah tell me about it - I gave up on Pereskiopsis for similar reasons. Crazy growth but these days I just graft onto Tricho seedlings if I need graft stock these days. Slower; but less of a nightmare and far more permanent.
@@AridZine Here the whole genus of trichocereus are outlawed :x pretty annoying, i would love to grow some of those..
Cant ever talk spines, and leave out the Stetsonia Coryne!! Also, you should see my young Tersheckii.... its got spines so long and plentiful that they curve to accommodate each other as it grows new areoles.
Yeah, you’re right! Can’t believe I forgot about Stetsonia in a vid about spines. 😅
