Arisaema 2012

A. speciosum

Well, it really should be, but from what I can gather the spadix-appendage is white in A.speciosum. On this plant it is clearly dark red, ( as it is on many web pictures of 'A. speciosum' ). Is this a ssp. or a wrongly named plant?

Ron Edrom are selling a red spadix-appendage as Arisaema speciosum Magnificum http://www.edrom-nurseries.co.uk/shop/pc/Arisaema-speciosum-Magnificum-p8556.htm

Hoy, to me the middle picture looks more like Arisaema wilsonii. Both others are certainly A. elephas though.

Thanks! Think you are right

 David, why do you not  also give a link to http://www.aroidpictures.fr/pictures.html in your signature ?

Thanks for that lead Davey.
Guess I need to do a little more digging. I'm thinking these commercial plants are hybrids.

I think this is unlikely as there are very few hybrids of Arisaema in cultivation.  It's more likely to be part of the wide variation of a species.  What's happened to Pascal, he hasn't been here recently?? he's very knowledgeable on Arisaema.

Thanks Diane, I just wish I could find any reputable record of there ever being a red one found and described as such. No luck yet. But I am persistent, 
G and L Gusman record no such thing in A.speciosum in their Monograph, having apparently seen thousands in the wild. I know Forum members have also seen these in the wild and I hope they can confirm the red spadix appendage.

[Maggi Young]

Pascal decided to leave the forum.

I believe, from what he has told me that he disagrees with much in the Gusman's book.

David Scherberich is another forumist with an extensive knowledge of the aroids- I commend his websites to you.  He has photos of a red A. speciosum http://www.aroidpictures.fr/SIKKIM2003/arispeciosum977.html

Thank you Maggi for the advertising ;-)

I must say that the majority of A. speciosum I have seen had a spadix with a red appendage. I don't think that the color is very important, there is usually a lot of variation in Arisaema inflorescences, especially in the color of the spathe and/or the spadix.

A. speciosum var. mirabile is distinct though, having a distinctly spongy/rugose spadix appendix and from my observations growing at higher elevations than the typical variety.

[ronm]

Thanks everybody for your help and leads. It is clear to me now that A. speciosum can have a red spadix-appendage.

This Arisaema candidissimum has been in flower for about a week.
Other pots of the same clone are just appearing.

[dscherberich]

Very nice A. candidissimum clone, Fred!

[ronm]

A.costatum

A beetles eye view. I love the way the light shines through the 'windows' at the back of the spathe tube / limb.

[ronm]

A. tortuosum

It's the almost 'reptilian' pattern on the stem that I really like on this species, . That and the outrageous spadix appendage, .

[daveyp1970]

Its a stunner Ron!

[ronm]

Its a stunner Ron!

I think I've been lucky with the ones I have Davey. All of them have the most beautifully marked pseudostems ( or is it just the cataphylls that are patterned? ), which I understand is not always the case. Unfortunately I dont have any with the purple spadix appendages, all of mine are green. Something to look out for.

[i]A. dracontium[/i], Pinellia pedatisecta

Closely related to A. tortuosum, is this species from North America. The ' Asian Green Dragon'. Apparently one of the most often grown Arisaema,( or so I am always being told ), here in UK. It is easy, and reproduces fast, perhaps considered a weed. Maybe a little plain? It would appear that 'true' A.dracontium is not easily obtained in Europe. All who think they grow A.dracontium in UK may want to double check their plants. . Thank you for correcting my mistake,
