Hi Ortwin,.

a great topic that you did on

40 km east of Hannover is classified as zone 7 b, where the years are of course very different.
15/16 was a right mild winter, 16/17 also not as cold, but with a 14-day period with up to - 15 ° C cold nights.

Therefore I also expect that my in the autumn 2015 ( Typhonium venosum in original condition? post #154) Sauromatum planted from venosum 'Indian giant'; frozen It is Hardy in the Netherlands.
But see here: index.php? page = attachment & attachmentID = 3476

Also, a planted from dead horse ( www.amorphophallus-forum.de/helicodicero...n-f27/t5759-f10 post #13) has survived us winter looks only: index.php? page = attachment & attachmentID = 3478
This has me after the winter already überrrascht, because I had planted a smaller bulb years ago which has not überlbt the second winter.

Then I had a bucket of Typhonium fall / Sauromatum giganteum out forgotten and thought that I the kind now even my own... have called
S. giganteum always late drives out - and Lo and behold: index.php? page = attachment & attachmentID = 3480

Likewise with a bucket t. horsfieldii / Sauromatum horsfieldii: index.php? page = attachment & attachmentID = 3477

What surprises me in your description is that the larger konjac will not survive it. Helps there possibly a gravel surface in the Auspfanzen, so definitely not like waterlogging occurs?

Maybe you should try such attempts with more species, of which one has enough primary Cormels...

Here Alan Galloway writes that with him over a few candidates, (zone 7B) are Hardy:

There, you can search with the subject line of messages even after another...

Happy growing, Bernhard.

Alan's list is updated regularly by him, but he seems just waiting for Facebook to maintain the current version. To see the Amorphophallus group, last update yesterday. https://www.facebook.com/groups/amorphop... 40365345993639 /

Hello of Andreas,

do you have a Guttenberg keyboard???

With the 3 keys: CTRL, C and V...

Happy copying and pasting, Bernhard.

Hi Bernard,.

I wanted to not simply copy Alan's list without asking him.

S. horsfieldii I have wintered well this winter in the pot out there, because he simply has crept in a bucket with my Frühlingsblühern. Nevertheless, he has had this year of three flowers. The bucket was completely unprotected outside normal potting soil in frost and rain.

Hello of Andreas,
very commendable!
Had I not made too... I've written him short and he sent the list then me, copy them... in the Forum with the OK
Happy growing,
Bernhard.

Hi Bernard,.

also very commendable. :-)

I'm assumed that most are group here anyway in the Amorphophallus and therefore live to read that, but it is of course most practical.

Fans of forming tubers, tolerant Araceae,

Please beware that the species does not escape you...

When you consider the Vermzehrungspotential of some species, you can safely be invasive bezeichtnet.
E.G. Lysichton americanus is on the EU list of invasive species - https://de.wikipedia.org/wiki/Liste_inva...eutung#Pflanzen

(Still) Happy growing,
Bernhard.

Hi Ortwin,.

Dracunculus vulgaris feels in our poodle probably out there! This winter we are trying for the first time a Helicodiceros muscivorus to overwinter.
Sauromatum venosum and back giganteum and A.konjac sometimes as breeding tubers in the ground and then exorcise.
July's but not very late for the shoot of the konjacs. Even with warm winter, some are with us until August full of SAP

Hi Ortwin,.

I have no other types of ausporbiert...

From the large (ever hibernated) tuber by Indian giant I've found only a pulpy mass, but some primary Cormels survived it and are driven out (I have elsewhere, I think, already once written).
Helicodiceros and Dracunculus vulgaris were good this summer right – I'm curious to see whether both in the spring to come back and possibly also blossom.

You've written earlier that you wanted to try kiusinanus - she did not survive apparently then.
Was that the only new species you've tried? You wrote "The rest of the varieties sampled from was no longer"...

Happy growing, Bernhard.

Hi Ortwin,.

You write what pot; did you plant the tubers outdoors in a pot or in the garden?
This makes I think a big difference because a pot of course quickly freezes through.

Love greetings
Michael

Hello

I have Dracunculus vulgaris, Arum italicum and Arisaema candidissimum winter survived the last. Planted in my Araceenbeet. The Dracunculus also beautiful large flowers have made this year. Most tubers have I bury at least 30cm deep and covered over the winter. For a week we had-17 degrees here in the top.

This year I'm planting out fracture even Konjac and Sauromatum.

Greetings Ralf

Quote from »Ortwin«

A. kiusianus did not come back either.
It had quite a few growth problems this year. She moved back in much too early. I first have to see what is left in the pot. In an emergency, I still have seeds; then I'll just start all over again.

This does not surprise me, because kiusianus is considered a species that likes it a little cooler and reacts with the retracting at temperatures above 25 ° C. A corresponding note can also be found in the Amorphallus_soil_dormancy_list.

... whereby this note is not directly in the table, but in the spreadsheet "Cultivation" - so something hidden....

Nevertheless: Happy growing, Bernhard.

Typhonium venosum is certainly hardy in zone 7b, forgotten tubers in compost have grown excessively into my tomatoes. Here in February the temperature dropped to -12.5°C.
In http://plantsoftheworldonline.org/ you can see the distribution of an art. Then you can compare winter hardiness cards with USDA.
