Manihot carthaginensis and/or grahamii
Two questions.
1.Has anyone in the UK still got one of these Manihot still growing? They were getting quite popular before the colder winters.
2. Are Manihot carthaginensis and grahamii as grown the same thing? They should be separate species, but I'm not sure I've been convinced that what is circulating isn't all the same. Seed of Manihot carthaginensis is , but shouldn't be hardy; I'm hoping it is mislabelled grahamii!
Chad.

Well, I've definitely got M. grahamii and it's done well outside all winter and is putting out new leaves. Mind you it's only a baby yet, about 3ft high.

Re: Manihot carthaginensis and/or grahamii
I was lucky to get some Grahamii seed and cuttings from a private garden 8/9 months ago. A few months on i have several plants planted out and two in pots for " insurance". The best is this 4ft seed grown , now flowering ............
Potted insurance plants..........

Re: Manihot carthaginensis and/or grahamii
I've never tried with cuttings, Taffy. What method did you use and what success rate did you get, please?
Pete

Re: Manihot carthaginensis and/or grahamii
Hi Pete, cuttings were about 8" long, into a large pop bottles so i could see if they were rooting without any disturbance , 50/50 compost and perlite, approx 20c and i had 100% rooting .

Thanks, Taffy. I might give that a try.

Re: Manihot carthaginensis and/or grahamii
Having read this post I quite fancy one of these, although I suspect the cold summers here are not Ideal. The only supplier I can find is Treseders which is a bit of a round trip for me! Does any one know of an alternative source. The other option is seed from USA. Do they grow easily from seed. Thanks Jas.
