What do you mean?
What do you mean, Sonja?

From the flower, this could also be polyphyllum...

Whether gigas in the pot and in size already blooms, I can not estimate, but the only gigas flower I have seen so far was huge and the plants also:
Botanical destinations in Australia? Figure 5 and 6 shows the flower
The flower is also much larger than that of polyphyllum and also not drawn as that of polyphyllum.

According to the description of the plant on offer on ebay, I actually assume polyphyllum, because the leaf of a D. gigas becomes much larger than 1.50 to 1.80 m....
here is an ununfolded sheet in the Berggarten Hannover:
Amorphophallus gigas
I have to take a photo of a larger leaf in the mountain garden again these days.

Article description at i-bäh:
"Dracontium Gigas ( Amorphophallus ) young plants 10 to 15cm. ( still ).
After 5 years of care, I can now also make others happy with these plants. Dracontium Gigas is very close to the Amorphophallus in the genus. When I grew, I always had more than one leaf. Mostly there were 3 with a height of about 1.50m to 1.80m, where new leaves were always shoots out before the smaller ones died off. There is no resting phase as with the direct amorphophallus species"

Happy growing, Bernhard.

Hello Ortwin,

this is what the D. gigas in the mountain garden looks like....

For me, the leaf stalk in the ebay offer also looks like amazonense or polyphyllum.

Happy id-ing, Bernhard.

Hello in the round,
and thank you for the posts and pictures!

I also wrote to the provider about ebay and he wrote that he knew what he was offering and the Drac. gigas is also one.
I didn't ask directly about the source, but it may also be idle.

What complicates matters is the fact that D. amazonense was handed over over 10 years by the Botanical Garden in MIssouri as D. gigas to gardens and private individuals in the USA.
In this paper:
https://www.google.com/url?sa=t&rct=j&q=... Km7N99BEB-zeJ-A
in the penultimate paragraph to D. amazonense.
Therefore, many D. gigas that are on the way are just D. amazonense, and are of course passed on as gigas.

As far as amazonense and polyphyllum are concerned, these two are very difficult to distinguish;
see D. amanzonense in this paper:
https://www.google.com/url?sa=t&rct=j&q=... kpbFlXUVXV2UEvE
there on p. 610 under "discussion".

Happy reading, Bernhard.

Hello Ralf,

I think there are Dracontium gigas in culture.
In any case, they were collected, whether only by Thomas Croat at the bot. Garden in Missouri or by others, I don't know.
The plant I saw in the Botanical Garden in Cairns Is already a gigas; in the Berggarten in Hanover.
For the latter I could certainly get the data on the plant from a gardener there, from which it would be possible at least then to learn from where the Hanoverians got their plant from.

At the Hortus Botanicus in Amsterdam there is also one or two:
https://dehortus.gardenexplorer.org/taxon-24096.aspx
and Hans Vissers works there as a gardener and has once posted photos of the flowers here:
http://www.aroid.org/gallery/vissers/

In Bonn there is also the type:
https://twitter.com/BonnGardens/status/854970248738598912

What is striking about all these plants (Cairns, Hannover, Bonn, Amsterdam) is that the leaf stalks are very similar and differ significantly from polyphyllum and amazonense (at least from the D. p. and D.a. in a size of 1.5 - 1.8 m) and the flowers always beside very different thick and large leaves. Also, in my opinion, they differ in the form of flowering from that from the ebay offer. I can't judge whether this is due only to size.

Happy id-ing, Bernhard.

Dracontium fans,

today in the Berggarten Hannover: index.php?page=Attachment&attachmentID=6311 index.php?page=Attachment&attachmentID=6312


I suspect it's this plant.... Amorphophallus gigas

I hope I don't miss the blossoming....

Happy blooming, Bernhard.
