Podophyllum 2011

Hoy - A nice aurantocaule. Has it survived your bad winter? I seem to have lost all aurantiocaule seedlings here over the winter and they were stored indoors frost-free. It seems to follow in the footsteps of difforme. Do other forumists have similar problems with this aurantiocaule?

In Stern aurantiocaule's winter hardiness was questioned, at least in Britain.
 
johnw - +16c here yesterday.

Very nice P aurantiocaule...Hoy!

Thanks, Stephen! I bought it from Glendoick some years ago.

And thank you, John! I am waiting for it - it hasn't surfaced yet but Podophyllums are always late here. I hope it has survived the freezing this winter

No problems with the hardiness of P. aurantiocaule furfuraceum at least, seedlings survived three weeks of temps down to -20C in the cold frame, with no snow cover. Seedlings of P. delavayi died, ditto for some double hellebores. Our "lady in Beijing" mentioned that her current offering of P. aurantiocaule was sourced in N Vietnam when I was there last fall, so they are presumably less hardy than those from W Yunnan/Tibet.

Hoy; setter den frø, og kunne du tenke deg å bytte bort noen?

Arisaema - Very interesting. Stern indicates ssp. furfuraceum is a bit hardier than ssp. aurantiocaule. As my book is in storage I cannot check to see if the latter also comes from areas in China that have colder winters. Have you tried any ssp. aurantiocaule outdoors?

It is surprising your delavayis died. I wonder if they may re-sprout from the roots.  I intend to try a few outdoors soon. I have mentioned in the past that we can grow no genera outdoors with species name delavayi!  I have put delavayi pollen on pleianthum so maybe they will be hardy, however none have that remarkable foliage of delavayi itself but they are fertile so maybe a back-cross is in order.

Should you ever want to trade seed....

We have not heard anything from Robin on the forum for a very long time.  Hopefully he will return.

Judging from the distribution and altitudes listed in Stern's book they should both be quite hardy - and neither should occur as far southeast as Vietnam...  I don't grow P. a. ssp. aurantiocaule unfortunately.

P. delavayi appears to have survived the cold outside in the garden, the rhizome is still solid. It's survived some 8 years unprotected, so I'm going to be very annoyed if it doesn't show! The seedlings are completely dead, but they were only a year old.

Remind me of seeds in July, or I could send a small rhizome if you'd like?

[johnw]

Arisaema -   Good to hear the rhizomes of delavayi are sound.  I guess I will wait until my delavayi seedlings are larger before I plant them out.  I will PM you re: seed, thanks.  In the autumn I can send you a delavayi x pleianthum seedling if not too large, they are already up and growing strongly under lights.

(I'm delighted to hear that the delavayi curse may be broken with a Podophyllum!)

When the book surfaces I will have to see which species occur in Vietnam though they will be useless here.  Perhaps PhilipMacD has received the same Podophyllum sp. from Beijing and can report back. He is in Taiwan at the moment and then heads on to sw Turkey.

If not then there's always an Incarvillea, a Geranium, an Iris, a Thalictrum, a Philadelphus and a Morina delavayi - all extremely hardy plants

There's one Podophyllum tonkinense at least, considered a synonym for P. difforme in FoC and as P. versipelle in Stearn, but it's red flowered. I brought back some gigantic rhizomes from Beijing, so hopefully they'll produce a few flowers later.

I haven't noticed fruits but we are often not home at that time of the year.
Finner jeg frø så bytter jeg gjerne!

[arisaema]

Flott, takk Hoy!

P. delavayi appears to have survived the cold outside in the garden, the rhizome is still solid.

Scratch that, it's dead, all green and mushy One more winter like this and I'm emigrating south!

[johnw]

I crossed delavayi x versipelle in 2009 but so far the best here seems to be this one, the same cross by Philip MacDougall.  No doubt he was using his best delavayi.

[johnw]

I see this delavayi x versipelle shown above is going to flower.  I wonder what the flowers will be like and also wonder if anyone can tell me if viable seeds are produced by these hybrids.  It might be worth doing a backcross with delavayi or even an F2 with a sibling.

[Tony Willis]

John I have one which is clearly a hybrid with delavayi,other parent not known and it produced viable seed last year when pollinated with delavayi

That's good news Tony.  I should put delavayi on the hybrid here to see if we can get a delavayi look-alike with extra hardiness.  Given Arisaema's loss of all delavayis I think we should prepare for the worst.

At last! It has survived the cold freezing winter without snowcover. Plants emerge out of the moss almost ready to flower!
