Title: Arum 2011
Post by: Hans A. on March 01, 2011, 09:49:53 PM

Arumseason has started with the beautiful Arum creticum Norman Stevens form.
The purple/dark reddish stalks make a fine contrast to the white flower and the green leaves.

Wow, the dark stalks do stand out, don't they.  Not a variety I've seen before.  Thanks.

Thanks Paul - noticed the posted pic is very dark and the colouration of the stalks hardly visible, so here two pictures which show this feature better.

I'm distributing this one (Arum creticum 'Norman') but never had so magnificient plants. I'm allways afraid - will I* have them the next spring or not. Oh, this marvellous climate on Balearic islands...

Thanks Janis - this is one of yours ;) It is really a beautiful and a big plant now, but did not produce any offset so far. A good group of this clone should look fantastic!

With me it increases quite well. Sometimes some are lost, but in general I'm satisfied.

Thanks Janis, it is the third year growing here, so maybe the first offsets will come next year.

Arum palaestinum

Found this:
 
       

Arch Pharm Res. 2007 Aug;30(8):927-31.
A new pyrrole alkaloid isolated from Arum palaestinum Boiss. and its biological activities.

Abstract

The phytochemical analysis of the ethyl acetate fraction of Arum palaestinum Boiss. (Araceae) led to the isolation and identification of a new polyhydroxy alkaloid compound; (S)-3,4,5-trihydroxy-1 H-pyrrol-2(5H)-one (1), and other five known compounds; caffeic acid (2), isoorientin (3), luteolin (4) and vicenin 11 (5), as well as the rare compound 3,6,8-trimethoxy, 5,7,3',4'-tetrahydroxy flavone (6). The structural elucidations of all the compounds were based on spectroscopic data (1H- and 13C-NMR, DEPT, HSQC, HMBC and NOE difference techniques) and comparison with literature data. Investigation of the antioxidant activity of the ethyl acetate fraction indicated its strong scavenging capacity for 1,1 -diphenyl-2-picrylhydrazyl (DPPH) radicals (SC50 3.1+/-0.82 microg/mL). Moreover, the treatment of different human cancer cell lines with the ethyl acetate fraction led to dose-dependant suppression in the proliferation of both breast carcinoma cells (MCF-7; IC50 59.09+/-4.1 microg/mL) and lymphoblastic leukemia cells (1301; IC50 53.1+/-2.9 microg/mL); however, it was found to have no effect on the growth of hepatocellular carcinoma cells (Hep G2).

Hi,
I've posted some queries/observations about Dracunculus canariensis and D. vulgaris in the general section... I thought you Arum experts might have some comments.

Sorry Anita, I'm by far an expert on these. All I know is that they are weird plants indeeed.

Just got this one in flower, Sauromatum venosum. I have read a description that Beelzebub would have choosen these as a bouquet for his mother in law. Well I can't say it really gives a springtime flower feeling and it smells like rotten flesh too. Luckily the weather is great today, if it was freezing I would have to keep it inside because it isn't very hardy either.
It has got nice leaves though, but I think I will not keep them for next season.
Anyone interested for an exchange?

Arum balansanum a quite rare and diminutive species the flower only 12cms tall and hidden under the leaves.

two more arums. These are grown in a frame and as they flower the flower is always facing away from the sun.

Arum rupicola about a metre tall
Arum sp from Turkey Tavsanli this may be related to balansanum shown above.

two views of

Arum conophalloides var virescens

I collected this South of Van in Turkey in 1991. It is featured in Bulbs by Phillips and Rix page 193

Yes, Tony, it is exactlythe same plant.

Post by: kiwi on October 13, 2011, 05:56:46 AM

The first, another Arum creticum, the second I post with interest.
I had recieved it labelled as A. apulum.
I see another very similar posted on page 1 as A cyrenaicum. My plants of A. cyrenaicum are more reflexed at the tip of the spathe but very similar in colouring , more orangey than purple though.
(searching folders for photos)
When you google image both plants you swear you come up with the same pics.
Can someone help out there?
Cheers,
Doug.
