Aroids (the family Araceae)

[Lesley Cox]

I absolutely agree. Almost wraith-like in its whiteness. Something from a ballet perhaps?

Hello Lesley

Yes I love this one and tried to pollinate it last year   
I try it again this year

On page 15 of this thread I posted the picture of Arisaema asperatum. The flower is over already but another Arisaema asperatum from another source has just open its bud. The next two pictures show the difference in leaves colouration: the first with splashes of broun (as shown in the Gusmans' book), the second with clearly seen broum rim.
And finally still another misnamed plant, received as Arisaema urashima but looks Arisaema ciliatum

Pinellia pedatisecta pushing up spathes like nobodies business at present.
I like this one, the 7 - 11 lanceolate leaves are attractive.

Be careful with most Pinellia's
before you know you have a million plants
almost impossible to kill

But if you have plenty of space they are beautiful

Photo of Arisaema amurense 'Jagged Edge' in flower earlier this year, and in green fruit now.  This was collected by Darrell Probst, selected for the unusual leaf shape.  In the second photo, the mottled leaf on the right is Diphylleia cymosa.

Mark,

Is that an official cultivar name for this plant? I have been growing it for over 10 years now as simply A. amurense "frilled leaf". Orginally bought from Crûg Farm who, as far as I now, got it from a nursery in Japan. I probably can ask a fellow Japanese collector to confirm but if my memory serves me right, it has long been in cultivation there. Any idea where Darrel Probst got it from?

[TheOnionMan]

It is my understanding that Darrell Probst collected this in Japan? or Korea?, he told me, but I've forgotten; it bears one of his Cobblewood (the name of his nursery) collection numbers that he gives to all items that he actually collects, listed as A. amurense CPC 9.26.97.6.  If I'm reading his Cobblewood Plant Collection number correctly, he collected this in 1997.  The name 'Jagged Edge' was coined by Darrell.

Even the young seedlings have the jagged edge

Oleg, your plant is more likely one of the naked green forms of ciliatum. Part of the description of jingdongense from the new upcoming FOC:

Leaf solitary; petiole greenish, unmarked, ca. 65 cm, proximal 3/4 sheathing into pseudostem; leaf blade radiate; leaflets 7, sessile, pale green abaxially, deep green adaxially, oblong-lanceolate, 7–8 × 1.4–1.6 cm, margin entire, apex acuminate. Peduncle shorter than petioles, ca. 55 cm × 2.5–3 mm. Spathe yellowish, without white stripes; tube cylindric, ca. 4 cm × 9 mm, recurved at mouth; limb arching, triangular-oblong, ca. 7.5 × 3 cm, apex acuminate with a filiform tail 4–5 cm.

So Arisaema jingdongense is not really a small species and should be yellow(-ish) flowering. I have seen pictures of what they regard jingdongense at a symposium and it is somewhat transluscent yellow.

Some plants currently flowering in my collection. The flavum is the form that occurs in the mountains of Yemen and South Arabia. A very robust form with a good yellow flower. The Arisaema franchetianum is the classic form that occurs in a red-brown striped form like this and a purple striped form. Both have the very lush, soft green leaves. The last 2 are of a species I posted a picture earlier in this thread, one of the (sub-)tropical species with the hairy appendices. Fully expanded the brush like appendix can be as long as 20 cm but is still a bunch of wires when the flower just opens.

These showed up a couple of weeks ago, can anyone confirm that both are A. wilsonii?

Arisaema consanguineum a clone with variegated leaf from Ellen Hornig's Nursery in New York State. This one could be called "Perfect Wave".

[TheOnionMan]

Nice one Arnold, I love the stem mottling.  I tried one of Ellen's A. consanguineum once, tubers given to me by a friend, but they didn't winter over
