Perennial (multi year) Cannabis plants/strains. Anybody any proof?

Hi ICMag family,

As the title says, I'm looking for some proof that Cannabis has the ability to be -in certain circumstances- a perennial?

I have read several stories of giant Cannabis trees that were years and even decades old.

But these are all just stories that I heard.

My foremost question is does anybody have any proof (pictures)? Or what is your opinion/experience on the subject?

Or is Cannabis the only dioecious annual plant out there? Or can it be actually an dioecious deciduous (and/or) herbaceous perennial?

Bonus question, can somebody post another type of plant that is dioecious annual? (Or doesn't any exist?)
Or is Cannabis dioecious because of selection by mankind?

Cheers.

'In certain circumstances'

We know that plants reveg under lights, it's not far fetched that nature replicates this somewhere in the world.

A plant that can lay dormant for several months through a cold period I'm doubtful but happy to be proven wrong.

^Could you post some info about the link you posted? Looks interesting, is it a perennial?
Also I'm not on Instagram. I can't check out those references.

Think in robert clarkes hash book they mentioned nepales plants 18 months and older.

Neither am I lol, had to dig through another site for browsing insta posts to find those...their new policy kinda blows and is forcing people to make accounts to view.

Its from North-West Balochistan. It doesn't specifically say perennial but says floral regrowth. Perhaps a multi harvest at the right long/lat but not full perennial? I'm not sure, would like to see what seeds from the variety would do in different conditions. I think I saw another post from the same area or possibly Pakistan of regrowth happening in a field in December or January.

Here's a picture of an Auto-Haze plant that started re-veggin' after it was harvested. Grew nicely for a while but then the cold air killed it. This was outdoors in Finland, so it gets a bit cold and dark here during the winter months. But had this been outdoors somewhere that's nice and warm all year, she could have lived to see another harvest. 3rd one?, I don't know about that Decades? That I kinda doubt.

I have copied the picture from your link and I'm posting it here so other people who don't want to click the link can see this picture also.
Please post into this thread if you might find some more info about it.

Also please keep in mind that with perennial I mean minimum 2 years. Not just a reveg of a fast flowering plant or some kind of 1,5 year tropical season.

I never saw a Cannabis plant grow back each year.

It sure would make guerilla growing a lot easier.

It could only happen in the warm tropics where daylight goes from 12-14 hours and back. That’s what I think anyway

For a true perennial plant to be it would have to bud and shoot vegging branch shoots out at the same time...if its just chok full of nothing but bud it wont work....cuz the buds would age... but il show you a picture of wat I mean ...let me get someone to send me a picture.

.I have only seen seeds or clones that when planted outdoors in S calif in the ground say in Dec grew, started to flower because of the short photoperiod, and then by april-May regenerated veg because of the daylight hours increased to make them veg, that does not mean they are perennial, just that they are trying to respond to the photoperiod.

In general Cannabis clones made from veg mothers do way better than a re-vegged mother being flowered mostly harvested and stuck under long light photoperiods to be grown veg again, to be flowered again. it can be done but not in nature, and the mother plant will waste a bunch of time resetting its veg/flower clock, as well as the earlier maturing varieties do not want to survive re-vegging as easy as late maturing, long flowering varieties.

I can take clones from late, long maturing plants that have flowered for 12+ weeks and stick the clones under 24 hour light and often get then to re-veg I have done it many times, it is not hard with the right varieties, handy to do selections of the best seedlings of a massive crop to avoid having to clone every single female, instead just wait until almost done flowered and only clone the very best to keep for the future, this is not easy with earlier maturing varieties.

I have read many claims that people have seen Cannabis growing in the wild that was obviously 2,3, years old that flowered, revegged, flowered, revegged, flowered, but I have never seen it myself and I have looked and looked in dozens of countries where Cannabis grows wild and where Cannabis is grown by man, if a plant is 20 feet tall and massive in size I suspect people think it could be annual, I predict it is not.

The closest I have seen are Autos (age determinate instead of photoperiod determinate) that will continue to flower, and making new veg that also flowers but if they are exposed to extream cold they die, on the equator maybe some would continue to flower and continue to make new flowers not really perennial but more than annual?
They are not what I like to grow, I like a plant that grows veg, flowers and at the end of flowering frosts out with resin, as resin is the name of the game for me.

All very great responses so far guys. Thank you all already for this.
If anybody can find some more info then please post it here.

Also does anybody have any info about the additional question?

Bonus question, can somebody post another species of plant that is dioecious annual? (Or doesn't any/many exist?)
Or is Cannabis dioecious because of selection by mankind?

I grew a plant in summer of 2013 and revegged it after a partial harvest, flowered it again indoors over the the winter and put it out to reveg in April and harvested the plant for the final time in October 2014. I wonder how long I could've kept on repeating that cycle.

I read long ago that long-flowering zamal varieties in their places of origin, such as Reunion Island, Madagascar ... due to the photoperiod grew for years and flourished when they wanted.



"According to local growers, zamal flourishes on the island when it pleases, regardless of the night hours:

«To get a good quality of Zamal, it takes at least 8 months of flowering outdoors, but the best landraces take up to 36 months before flowering. The plants reach 4.5 m in height by 3 in width and produce from 2 to 6 kg each, if you are lucky they do not suffer from any infection. Some, like the mangue-carotte, can be kept for 20 years! »Explains Cab Pacino, member of the Bourbon collective and specialist of the zamal.

Contrary to the culture in Europe where plants bloom on a fixed date (when nights lengthen), with zamal flowering is triggered randomly after a period of indefinite growth: “Our landraces not only take a long time to flower They also decide to flourish when they feel like it. The harvest is never harvested in the same period! »

Cab Pacino is passionate about all the varieties of Zamal: «I have, in my collection, the most difficult landraces to find. They are the Kalité Filament rouge (red pistil) and Filament blanc (white pistil) of Cilaos and also the Kalité Salazie, some types of Zamal landraces that are cultivated in the circuses of the island at more than 1500 meters of altitude. Kalité Sainte Rose (Santa Rosa) and Kalité Pêche (peach) are very rare as well. The Kalité 1 or 3 taffes type landraces and the Kalité la Kour are especially powerful with THC percentages exceeding 25%.

They are often grown by the "gramouns", the island's grandparents who traditionally use them for their herbal teas. These sativa-type varieties grow disorderly with strong development of the secondary branches and very long primary leaves: the longest I had was 28 cm! »"

^Thanks for sharing. The Zamal legend is one the most famous stories that keeps being told. I believed it all when I read about it the first time. But the more I looked into it, the more it became apparent that there is no proof to back it up.

Here is a thread about it:
https://www.icmag.com/ic/showthread.php?threadid=307924

Also check out the strainhunters forum about it. Franco who has personally visited the islands and went looking for it, said after he came back that he found no proof but did hear tons of tales from the locals.

Remember: perennial is +2 years. It's not the same as being able to harvest twice or keep it going for 1,5 years.

I want to see a picture of those 20year old plants...

Also the Kanak legend from New Caledonia about an old mother tree devotion!

The vine is a different plant but... Vibes Cvh!

I would say that perennial cannabis is even possible without the human help and into the wild but only close to the equator and with altitude?


(The word's construction canna'bis "bis repetita") ?

The pictures have been sent to me so sorry there not beter....il try an get him to send full plant pictures...think he's just sent a picture of one branch so you can see wats happening...but like you can see its just throws masive calaxes as flowers up an down the stems...evry so often it just sends out new shoots upwards and the older growth dies off...well the guy picks it off cuz the older calyaxs start browning and the old leaves eventual go yellowish white an die off....been tested under multiple light regimes with no change...it grows as it wants.....you can take cuttings off it an it grows the same.....i put a thread up here called "plain weird, help from more experienced needed"...which was put up almost a year ago I think, but wen the guy first showed me an was trying to get help....he wouldnt tell me at the time exactly wat it was...but later on revealed its some south east asian landrace type...people can take a look there too an youl see a bit clearer how the shoot just grows upwards.......evry so often on a full plant it seems to just over night send out long extended shoots an then slowly build up calaxes an crystal again....the smoke is quite minty but the high off it is weird...very uncomfortable..some help would be nice as to wats going on...like you can see here its older towards the bottom..with the more uper growth that is newer and greener

Ive never found any proof of perennial cannabis either cvh,
just stories of folks that claim to have , but ive tried every which way to get some to continue growing other than taking cuttings and they just dont like doing it ... they are definitely an annual and definitely not a perennial , so far as everything ive seen and done tells me ....



many seem to think it can be done in the tropics , but i live in the tropics and know many other growers here that are north of me closer to the equator , no perennial cannabis has been spotted,
my location is a few hundred kilometres closer to the equator than reunion ,

as far as i know that place is bordering the tropical zone ...



i grew a few zamals , none went longer than a season ..



its true that here we can grow a plant , harvest it leaving some branches down low , and it will regrow for a second harvest ,
but thats all in one season , not more than a year ... they dont tend to winter very well either ,, short cool days are not conducive to reveging...
