Title: preglacial relict : Streptopus amplexifolius
Post by: Hans J on June 19, 2012, 08:44:58 PM
Before few days I had the wonderful opportunity to see Streptopus amplexifolius in the wild here in Germany - here are some pics to show this very rare plant ( a preglacial relict )

a other very rare and interesting plant is this kind of moss ( also preglacial )
Huperzia selago and in the backround Scapania nemorea

Hans I like the Pinguicula and those orchids are lovely. Its nice to see the plants growing through the moss.

Hans,

Streptopus amplexifolius - what a fascinating plant!! Never seen a plant flowering from the underside of a leaf. You get a lot of this on certain types of orchids (bulbophyllum), but they flower from the centre of the leaf upwards.

Your plant is magical. Where did you find it? Judging by the walking poles in the first picture, it must have been quite a hike. ;) ;)

Thank you Maren !
I feel like you - this is really a fascinating plant !
For the first view it looks like a polygonatum ....but if you see the flowers so it is clear that this is a different plant .
Earlier botanist have it descript as Uvularia or Convallaria - a other big difference to Polygonatum are the fruits ...they are red ( more like Convallaria )
We ( my wife and I ) found two populations of Streptopus in the Black Forest in mountains woods ( Aceri - Fagetum ) - it was a hard and difficult trip - you are right we need the walking poles and also we need a rope ....it was a wild area !
A lot of rocks ,fallen trees ,and very steep slopes ...
We saw also Aconitum lycoctonum and Ranunculus aconitifolium -sorry no pics

We need 3 days to reach this area and back....it is not accessible by car ,train or bus...the weather must be perfect to make this trip ..otherwise it is impossibly!!!

Streptopus is a interesting genus - is grows "circum polar" - that means few stations in Europe , America ,Asia

Hans: Fantastic magical pictures and info re-the Streptopus! You deserve that beer after such a plant expedition! I thought that this was a North American species, so very interesting that it's found in Europe. I actually took a few pictures of a large plant in the local botanical garden here in Trondheim just a week or so ago as I had wondered if it was correct, however looking at your pictures and with  the  picture of the red berries in the autumn I think it is! Thanks for posting this!

Stephen ,

I'm glad that you like my pictures and infos !
Yes ...it was NOT only one beer after this trip ... ;D

I'm surprised that this plants grows so well in the B.G. in Trondheim ...it seems they like it .
The biggest plants what I have seen was 1,10 m heigh ...it seems your plants are bigger

I have never seen before this plants in any botanical gardens ...

Hans, I saw Streptopus amplexifolius often in het southeastern Poland mountains. It is not rare. I collected a plant in the Babi Gora region and is is very easy to grow in pots. Every year I get many seeds from the berries, and was succesful in getting new plants. Last year's sowing didn't succeed, surprisingly, but I hope they will germinate next spring..

In full leaf they are stunning plants growing up to almost a meter high

If someone is interested in seeds, please let me know in autumn. I'll have plenty

Hi Hans ,

many thanks that is interesting .
Maybe it is in Poland more common because there is a other climate ( we are here in a very warm area in South west germany ...the plants grows only in very cool mountain areas here .

How you grow your plant in winter ? in a greenhouse ? or in the garden ?

Thank you for your nice offer with seeds - I will contact you maybe later

Regards
Hans
Title: Re: preglacial relict : Streptopus amplexifolius
Post by: JPB on June 21, 2012, 05:11:10 PM
Hans, I've not yet tried it in the garden but I'guess it will not be a problem. I keep the pots sheltered from rain and excessive frost, but this is not necessary as the plant is very frost-resistant..

Cheers, Hans
Title: Re: preglacial relict : Streptopus amplexifolius
Post by: Hans J on June 21, 2012, 05:49:03 PM
I suppose also the cold would be not a problem - in the area where I have found the plants is it really cold ( there is a average temparature from 5° C ) ...but in winter is a lot of snow
In last winter I have lost a lot of plants ...the main reason was that we had no snow ( and unusual warm temparatures in December and January )
In my garden grows well ( without any protection ) Polygonatum verticillata - this plant grows alsoin the area where the Streptopus grow ( on more drier places )

Hans, I'd like to try the seed, please, if you have any left. What pH do the plants require and what soil types?
Title: Re: preglacial relict : Streptopus amplexifolius
Post by: JPB on June 24, 2012, 07:11:52 PM
Maren, I will collect fresh seeds of this year's berries and I'll send some to you. (August/September, I made a note). I grew them in Rhodo-soil and while the larger plants seemed to like it as well as neutral soil, the younger ones are better off in neutral soil. They do not seem te be very picky about soil, as long it is free-draining and humus rich.

Hans, superb! I did not know it grew in Europe as well. I've seen it in Washington and Montana and the pink species (lanceolatus) here in TN at 2000m. I also saw a species in Vietnam at 3000m. Would be interesting to see genetic work on these. I believe they are closely related to Prosartes which is common in my area, both maculatus and lanuginosum (formerly Disporum of NA).

Thank you Aaron ,

yes they grows in Europe ( in few places ) and in Asia too
A question : it is difficould for me which species grows in USA ( Canada ) ....
Are they really distinct from S.amplexifolius ?
When I look in Kew informations so they make many synonyms ....
Could you please explain a bit ?

Thank you
Hans
Title: Re: preglacial relict : Streptopus amplexifolius
Post by: Afloden on July 02, 2012, 12:10:32 PM
Amplexifolius is the most common species found in the mountains of the west, upper midwest, northeast, and in the southern Appalachians at high elevations. Some of these were considered species at one point or varieties. Then there is lanceolatus (roseus) which is fairly rare, and its hybrid with amplexifolius, S. x oreopolus. Last, there is streptopoides which, I think, is a small little plant in a few places out west. Here in the east both are rare and only in Abies and Picea forests at high elevations. I've seen each only once. Out in Montana I see amplexifolius frequently.

Hans,

Just caught up with this topic.  Another plant I'd never heard of before.  Thanks so much for showing us.  It certainly does look like a Polygonatum at first glance.  Fascinating differences though.

Thanks again.

The Streptopus look great with the fruit too, don't they.  Adds a bit more of a dimension to the plant, and the birds probably just love them.

I love the Epilobium and that lovely yellow Impatiens as well.  Thanks for showing us.

Hello Hans J.
I have overlooked this post until now.
I am amazed that it grows in Europe.
I think I grow it but as Disporum sp.
I will check my plant against your excellent pictures next year.
If it is the same it is quite hardy.
Cheers

 Hello Hans !
I've only see it on the forum Streptopus Amplexifolius , did you the picture of P7113479 of 20/06/12 nb  of Stephenb , berrys are long .
And your picture nb P7140293 of 21/06/12  the berrys are round !  Is this the same variety ?
Do you still have some seeds for a person late !
Thank you

Hi Christian,

I do have seeds from 2012 for you so please send me a PM with your address.

I cannot say much about varieties of S. amplexifolius. Sometimes berries on my plants are more like those of the Hans Joschko plants so I doubt they belong to different varieties as based on the shape of the berries.

Hans,

In the USA this plant, and S. lancifolia are native to at least 30 states.  While not very comon, they are not rare here. In most years, the NARGS seed exchange offers one or both [both garden grown, and wild collected].
