Gunnera Banned! What this means for you as a gardener.
Defra have classified Gunnera Cryptica, the now widely grown and sold hybrid of Gunnera tinctoria and manicata as an invasive species. This amazing widely grown exotic plant is fantastic for a jungle style garden but what does this new mean for us gardeners? I try and make it clear in this video plus links to the news article and scientific paper.

Looks like i'll be hanging around street corners and alleyways with my hood up asking passers by if they want to buy a gunera then!
Yet we can still buy a Sasa bamboo or buddleia
Thanks Kris for providing this information. However a law is only of any use if it is enforced. But like so many laws they never are.
Many thanks for the information
I have grown this in different gardens after buying my first plant in the 70s from Beth Chatto, I have also used it on a couple of landscaping jobs in the past when it was legally allowed, also known as Gunnera chilensis and had another name before that!
In none of the cases where I have used has it spread out of control, in fact it has grown in an identical fashion to manicata in one case for over 40 years, where are examples of this invasive habit? it is still or has been difficult to come by anyway.
Hello Kris, thanks for the info as I wouldn't have known otherwise! Always wanted one so brought one a few years ago and has been growing slowly for me, but I have poor soil so understandable. Pretty sure mine is a low risk it seems ha ha. Goof to know I can't share it now so need to make sure it survives then lol.
Carefully consider Google Earth before planting, leaves might be visible from space.
Been trying for years to get a manicata. Kept getting mis sold tinctoria. Finally got a manicata/ Cryptica
So I guess we really need to start taking care of the ones we’ve got!
It's not invasive in the UK however it could be in some EU countries. Same reason we lost water hyacinth. Unfortunately our civil service is so EU focussed still after 40 years of doing exactly what the Commission told them that they automatically and slavishly follow the EU's lead. Hence Gunnera ban.
Crazy, hardly Japanese Knotweed
This plant species: (tintoria, manica, and perpensa) are also highly medicinal for many diseases including cancer and viral
I've not seen any published papers on this. Interesting
@@YorkshireKRIS Just a search on Google for examples will give you the names of various researchers on Medicinal plants such as ResearchGate, Hindawi and many others
Hi! Love your videos, thanks for the advice
It’s not unlike me to get confused, so apologies, but to clarify, they are banning manicata? This is the reply I got from a local grower
“No they havent, there are a huge amount of variants of Gunnera, the Gunnera Tinctoria has always been banned. We studied Gunneras for years as so many garden centres and nurseries were selling the tinctoria labelled as manicata. We contacted the RHS about this as they had put there name to a few aswell as having them in there gardens. To get round this they changed the name of the tinctoria to cryptica this year. The Cryptica has now been banned as it is a hybrid of the tinctoria, but the manicata which we have is not banned. We are licensed by DEFRA and have started selling our manicatas to trade to get the manicata back out there, hopefully this has cleared it up for you, Yes Yorkshire kris is wrong on this occasion, Kris is not APHA”
Making me think I should divide mine for another part of the garden before the ban comes into effect. 👀
It would be good to have a video on gunnera alternatives, if any
You're just gonna have to settle for some well fertilised rhubarb grown in horse crap 😁
Thanks for the video Kris, I can't help wondering with the advances in plant genetics how long it will be before someone breeds it back to the original Manicata.
Manicata still grows in Brazil.
Hey kris I hope you are well and thanks for the update! Quick question... One of my yuccas which I saved from going to the tip in the spring has just started to send up a flower spike.. Is this normal for this time of year? My others never flower in winter so has taken me by surprise 🤷♂️ should I leave it to flower or at this time of year should I chop the spike to help conserve it's energy through winter?
Kris with the quick news! As much as I do understand the tinctoria genes and their potential to create a fast-growing and hardy invasive plant, I do wonder if there’s any widespread evidence of cryptica being invasive? It doesn’t seem to self seed very easily or spread rapidly via rhizome in my experience. It would be interesting to hear if it has become an issue outside of isolated cases or whether this is a blanket decision due to the genetic potential only…
I share your scepticism. I haven't seen any evidence of cryptica spreading in the wild but have seen tinctoria in Ireland
I had loads of divisions for next year that I can't sell now
Even the scientific paper from Shaw and the RHS last year stated that Gunnera x cryptica seeds are "rarely fully developed," as can be attested to by many a gardener trying in vain to make more Gunnera plants. Seems like an overabundance of caution given that it's quite difficult to tell the hybrid and the species apart. In my opinion, would it not make sense to try to eliminate just G. tinctoria from sale rather than take the beautiful hybrid with it, which logically would have less invasive potential? Obviously this is all new research ongoing but our Gunnera plants are being labelled guilty until proven innocent! The hybrid might have invasive potential, but the current evidence suggests otherwise.
Thank God I live in Ireland!
@@harrywolfe923 yeah, thank god you do too...
So, where G. manicata lives naturally, is it the true species, rather than a hybrid? If so, would it be possible/legal to import that stock, knowing it is not 'polluted' with tinctoria?
Yes there's true manicata in habit. The hybrid naturally formed in UK where tinctoria and manicata were planted together.
Ok, thanks for the awareness video. I have a Gunnera that is now 3 years old with nearly 5ft leaves. I love it and some friends want cuttings or seeds but I will now wait to pass these on. How do I know what exact Gunnera I have?
Check out my previous Gunnera videos where are compare the different types
Pass it on now while it's still legal!
Thank you very much for sharing this information. I have one 5 year old plant in a pot in my small garden that I now need to protect like a precious stone this winter.
Are they just going to go unchallenged?
I believe so
Thanks for the update. I am curious whether this will happen with Tetrapanax? Seeing as so many people have shared the horror stories online.. I hope I am one of the lucky ones, because my Rex staying in there 😆 will keep my Rex and Steroidal Giant pups in pots though
Give it 20 years and I think it'll be considered for a ban....
@@YorkshireKRIS that is enough for me to have plenty of growing fun haha
It’s not a great problem as it’s confined to private estate in West of Scotland
My two attempts at growing this have both failed,i wanted another attempt, damn!!
Oh no! It's unfortunately going to be missing from lots of gardens in the future
@@YorkshireKRIS what about seed?
@@user-rk1uz4ur4m that will also be covered
@@user-rk1uz4ur4m Only option left is to check and see if government papers pinpoint areas where the plant is most invasive, then grab yourself a cutting for the purposes of scientific research.
Can we not just start again with virgin Manicata plants from Brazil?
I bought a 'manicata' that turned out to be a tinctoria. I have kept it in a 130L container.
How do we treat the seeds / flowers? Are they OK to be left. Or best to be burned? I assuming composting isn't good.
Thanks for the update. Much appreciated.
They can be left on the plant in the garden and any seedlings disposed of
Ours been growing years but confined in brick old pond but last few years leaves very small? Should I feed it??
Feed and water
Can you take wild plants and put them in a pot 😢
feels like someone will import true manicata sooner or later
Europe and all RHS are gone crazy
It will only affect those that follow the rules, guardian readers & most of the population, (those who have been told to be scared of getting covey one nine) 😆
It'll affect a lot of people if they aren't for sale in garden centres
@@YorkshireKRIS yes but what goes on in private will stay private 😉
Gunnera I think they fought off gunerea ❤😂😂😂
