Arisaema 2016

[johnw]

I posted pix of this arisaema a few years ago and the closest we got to an id was A. heterophyllum.  However it is in flower right now, too early for heterophyllum so back to Gusman's book but Section Tortuosa left us baffled.  By sheer chance in the index I saw the name A. yamatense ssp. sugimotoi and recalled Philip McD had grown that one in the 90's and given one to us before he moved west. We lost that but apparently he had also given the original to a friend from whom we got this one.  Tough as nails and very prolific. So Arisaema yamatense ssp. sugimotoi it is.  Photos of the original today just a block away from us.

johnw  - 14c & sunny, just right!

Rather stylish looking plant. Tough and prolific completes a perfect description,  doesn't it?!

[Brian Ellis]

What attractive colouration.  We enjoyed all the arisaema in the woodland at Cluny House, very spectacular!

[johnw]

What is odd is when I was given permission to dig some of the original, that after a very dry summer, there was water just a few inches below the corms.  Odd the corms would tolerate conditions such as that.  I don't know how common is in the UK but will try to get seeds over in the autumn.

Brian  - I hope you took pix of the Cluny arisaemas.

Very nice Arisaema, and also prolific! - quite a combination for an Arisaema. The leaf looks a bit like heterophyllum indeed but otherwise very different. A. heterophyllum is just showing up here and doesn't offset (rarely); no seeds as well. Probably I need a second one.

Brian  - I hope you took pix of the Cluny arisaemas.

Have no fear, 'The Norfolk Eye' is processing hundreds of pictures from the weekend so you will see them!

[David King]

As Brian said I am ploughing through nearly 760 pictures but have taken a break to process the Arisaemas at Cluny.  Unfortunately there were no labels on these.

Fabulous - A. griffithii I would say, maybe a variety.
Besides Gusman book, this on-line ID key (Gusman & others.) is not bad at all: http://botu07.bio.uu.nl/Arisaema-L/key.htm

[Brian Ellis]

Fabulous indeed, there were clumps all over the garden!

Sensational!  I always thought griffithii was a bit more sinister looking than that though the leaves look to be correct.  Maybe it's when it first surfaces unfurling.

Gabriela  - Has this one been hardy for you?

And this lovely wilsonii? Ian showed in his Bulb Log does it have any hardiness?

[Maggi Young]

Our query Wilsonii seems very tough, John.

John,
One that looks as you say, more sinister, is A. griffithii var pradhanii. I never got too far away with it to be able to assess the hardiness. I tried it twice from tubers of dubious quality. Maybe started from a seed... but I kind of doubt it given its wild distribution.

Last year we were worried that a contorted Arisaema might be viral.  By summer it was fine.  Reply 446 through 455 here - {url]http://www.srgc.net/forum/index.php?topic=950.435[/url]  It had been grown as A. sikokianum from Garden North seed but Wim's Arisaema guru thought it was a marked-leaf form of pure A. amurense.

Here it is almost a year later at the Lurker's and I wonder if all still agree it is amurense itself.

I would also say it's A. amurense John, but don't count on my ID 100%. A. sikokianum was usually masqueraded by either serratum or amurense; once I also ended up with triphyllum Anyway, it is a nice silver leaf form.

And my Dancing crane Arisaema (A. heterophyllum) has started to dance  The way the foliage unfolds is what I like most about them. I missed the beginning this year and of course, it doesn't face the right direction (do they ever?)

[johnw]

Here's another one dancing in Nova Scotia, Arisaema dahaiense.  It took 5 days to fully open.
