This Arisaema amurense wasn't expected to flower until next year.
A nice surprise when I looked under the bench. ;D
Arisaema amurense
-
Looks good with that apple-green and white! :D
The next Arisaema to flower here will be A. concinnum. I like how the leaflets unfurl and spread.
-
Lovely looking A. amurense Fred. 8) 8)
Why wasn't it expected to flower this year? Did you grow from seed?
Your plants always look so strong and healthy. Wonderful :o 8)

The tuber(lets) were acquired to grow on for flowering next year.
Two of them have flowered which is more down to the seller than I. ;D
-
The first arisaema is A.yamatense. Any ideas about the second?
-
Hi Oleg,
I am amazed that you have Ariseama flowering most of ours are still under ground. It must be exciting to have everything flowering at once in the garden after the long winter in Moscow. Here it looks as if we will see the sun today, not been outside yet to see if it is any warmer.

Susan. Tis year is a perfect example of how it works in the continental climate. A lot of snow mid April and then +20 on April,20th. WQe are lucky this season not to have returning frosts. So the gardens look nice, everything is flowering together. Most of my arisaemas are kept dry and frost free over winter and give small shoots by April. So now I have 6 or 7 of them blooming. I wish you had warmer weather and hope that your summer will be nicer than last year.
-
Another one flowering now.
Arisaema galeatum
-
Some more for this week
1. Arisaema kiushianum
2. Arisaema serratum
3. Arisaema ringens
-
Arisaema concinnum is flowering now. I like the elegant twist of the spatha appendix. ;D
-
A.nepenthoides
About six weeks later than usual,
-
A. triphyllum
This is my first this year of this incredibly variable species.
-
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?
-
Can't help you ronm!
I have 3 plants I believe are Arisaema elephas but they aren't quite identical in the details. Any other suggestions?
-
Hoy, to me the middle picture looks more like Arisaema wilsonii. Both others are certainly A. elephas though.

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 (http://www.edrom-nurseries.co.uk/shop/pc/Arisaema-speciosum-Magnificum-p8556.htm)

Thanks! Think you are right ;D

David, why do you not also give a link to http://www.aroidpictures.fr/pictures.html (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, ;D ;D
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.
-
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 (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.
-
Thanks everybody for your help and leads. It is clear to me now that A. speciosum can have a red spadix-appendage. ;D
-
This Arisaema candidissimum has been in flower for about a week.
Other pots of the same clone are just appearing.
-
Very nice A. candidissimum clone, Fred!
-
A.costatum
A beetles eye view. I love the way the light shines through the 'windows' at the back of the spathe tube / limb. ;D 8)
-
A. tortuosum
It's the almost 'reptilian' pattern on the stem that I really like on this species, 8). That and the outrageous spadix appendage, ;D .
-
Its a stunner Ron!

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. ;D. Thank you for correcting my mistake, 8) 8)

A cf. consanguineum
Ex ACE 2031.
-
Arisaema candidissimum is flowering here. I like it very much with it's candy stick appearance. :D
-
Here is a mystery Arisaema from cw China AGCBC seed. Any ideas out there?
It emerges with consanguineum and the leaves look very similar, sort of a greyish green.
johnw - +26c & sunny.
-
And this one Arisaema taiwanensis is a beauty even out of flower. It's going to be a very big one.
johnw
-
John have you a picture of the underside of the leaves, they look really interesting...
-
brian - I think those markings are only on the ribs but I will check it out and photograph when light.
johnw
-
Cheers John, it's a shame if they are only on the ribs, but even so I bet it looks good from beneath.
-
Brian - Here are the undersides. Two of the good one with a slim black edge on the leavves and one shot of the plain green one from the same collection.
johnw - +24c, sunny and blowy.
-
Pretty darn smart foliage there 8)
-
Thanks John I appreciate your prostration to get the shots ;D It really does look smart.
-
I've not seen those kinds of stem markings before, on the RIBS of the leaves. They look very good. All the species with marked stems have that extra "something" that makes them very special.
-
Here Arisaema tortuosum in flower
this one is almost 1,5 meter tall
Roland
-
A Arisaema developed by Ellen Hornig in New York Sate.
Arisaema consanguinuem 'Perfect Wave'
-
I was at Joan Cooper's old house here in Minnesota (USA) with a friend the other day, and we saw what appears to be Arisaema dracontium. But we are just guessing. What other Arisaema species have that same pedatisect leaf form?
-
As far as I know A. dracontium and A. triphyllum are the only native North American Arisaema species.
Regards Thomas
-
Thanks, Thomas. I was thinking she may possibly have had an Asian (or otherwise foreign species to North America). Does anyone know what other species have that Voodoo lily like leaf form? This is the plant in question:
[attachthumb=1]
-
Hi Rick,
The only one I know with this leaf form is A. heterophylum.
Although one of the experts on the forum may have other thoughts.
Graham
-
Thanks, Graham. From the PBS, I see also Aa. kiiushianum, serratum and thunbergii. A. dracontium still seem the best fit, though, at least just from the one look I had.
-
Fruit of Arisaema consanguineum
-
I understood that Arisaema franchetianum was a late grower, however, the two small tubers that I have are only now in leaf. The smaller of the two finally opening in the last couple of days.
How are other peoples' plants of this species?
-
Here in Aus, it's Arisaema flowering time at present. Currently a few different ones in flower here, including ringens, speciosum, amurense etc. I must get around to taking some photos. :-\
-
Here's a couple in the garden this weekend.
-
Nice plants - will these be planted in the ground when you have the new garden ready, Doug, or will you keep them in pots?
-
Hi Maggi, they will go in the ground in my new shade house garden, hopefully next autumn, depending on Wether I finish building it in time!
