Fastest Growing Cactus?
I'm just curious, does anyone know what the fastest growing cactus in the world is?
Depends on what you mean by 'fastest', more apical growth (growth higher quicker) or more biomass per year?
Pereskiopsis/Pereskia apply to the first, the mother plant I established this year put out several feet of growth.
As far as biomass goes.. id personally have to say the answer is probably Cereus or Trichocereus. Some of the largest established specimens will really put on some growth in a given season.
I just woke up and am tired, there a chance I hit way off the mark lol, so someone confirm/debunk please!

Dont really know the answer to that one, but in my collection, first its Selenicereus chrysocardium. Cylindropuntia spinosior is next and then good ol cereus peruvianus, just my observation.
Pereskiopsis grows really fast too but it never gets more than 10 inches long and Im cuttin them up.

I'd say there are too many variables to claim a particular species as the fastest. I have a trichocereus that hasn't grown in about three years and those are typically fast.
I think you can categorize some plants as faster growing and others as slow in relation to each other, but with living things there are no guarantees.
Aztekium are among the slowest growers compared to other cacti, but A. hintonii is much faster growing than A. ritteri.

My P. pringlei is ridiculous. Add another 10" of height this season to the pic in link.
That's about 4 liters of mass.

I'll nominate this species as having the potential for fast growth in favorable conditions.

Wow man, what species of Trichocereus? I've never encountered anything like that. I should have been more specific, the Pachanoi species is a very fast grower and excellent for landscaping around here. The bigger they get, the faster they grow.daiv wrote:I'd say there are too many variables to claim a particular species as the fastest.

It is T. tersheckii I'm pretty sure. Anyway, it is unhappy and sitting dormant. This is not "normal growth" for the species - just an illustration of one variable.
I agree, T. pachanoi grows so fast it can't hold itself up and falls over. I suspect that having those small/thin woody rods instead of a more formidable skeleton is part of the reason it can grow so fast. But a look at DW's Pachycereus does damage to that theory.

I forgot about Harrisia pomanensis, I have a few stems that have grown 4 to 5 feet just this season, not to mention the 20 or so giant flowers and fruits it produced. But as far as mass I think few can compare to dogwoods pachy.
I agree Daiv, A subulata is a fast grower for sure.

I was about to get to that. I highly recommend P. marginatus, it grows like a weed, and can form a living fence in no time! I was able to bend over and look at the top of my P. marginatus easily in the beginning of Summer. Now, I can barely bend over to see the top.Ocotillo wrote: I've never had anything grow faster than P marginatus. One went from the size of my thumb to slightly more than 18" tall last summer. And this was good, meaty growth, not etiolation.
Re: Fastest Growing Cactus?
Pereskia's will grow rapidly if grown in a high humidity "Turkish Bath" type atmosphere. Conditions rather different to what most cacti prefer.
