Viable Acer griseum (Paperbark Maple) seeds?

Today i took some of the griseums together with a variety of japanese maple seedlings outside for the first time...

 

Good evening T, I'm glad it's warm enough there for those little ones to be out. Over here everything is going back under cover. Just so cold.
They all look like they are coming along very nicely. You are getting an amazing success rate.

 

Well it is still cold here too and i will place them back in the greenhouse for the nights. It will get a little warmer the next week and i want them to be outside all the time as i need the space for other seeds and plants... yes it all went terrific with the griseums and the jm’s i love the colours...

 

You have tended them well T. A deserved 'pat on the back' as they say here.

 

Haha thank you!

 

Just showing that bad weather for humans is not bad for the plants…

 

What a beautiful garden you have there T and farmland surrounding you, 'lovely'. Can you feel the envy coming across the sea!!? Lol.

 

Haha i feel it, but it’s a lot of work my friend…

 

All lovely gardens are T. That is something so many people don't realise.

 

Hello Acer Griseumfriends!. I am very curious at how your seedlings are doing and i hope some of you had success and can show some nice pictures?
Mine are still doing fine. Some grow a lot faster than the others, but i must say that i didn’t expect that such a great number of them would get this far.

 

Well lovely people from this forum. The acer griseum’s still grow very well and everything is going just really fine at the moment.
I just checked out my garden and the acers and suddenly i realized that this specific forum and especially some of the members of it created just one very toxic moment in my very happy live and i want you to know that just this has made me extremely happy!
I want to thank all of you for this special feeling as i can’t imagine myself being this happy without your input and help on the negative side of live.
I wanted to share a peace of knowledge, was willing to send seeds and manuals for free, but none of you was willing to take my hand and now you are there without pretty little trees, and without the knowledge to grow these little gems at all.
I hope that all of you have learned something from this experience and that you will treat someone else who likes to share something nice with you in a nice way.
Thanks for the few who were very friendly to me and the rest, well stick it where the trees won’t grow..

 

I do not follow the Maples forum too closely and did not see your offer. Even if I had, I doubt that I would have been able to take advantage of it because of the import regulations imposed on seeds from elsewhere in the world. People in garden clubs I belong to are very upset with changes in regulations brought about by Britain leaving the EU.

Frankly, I don't think anyone who loves plants and gardens is lacking appreciation for others who want to share - we do it all the time. The trouble for us here in Canada (and perhaps all NA) is that it is very complicated and usually expensive to import plants from Europe and elsewhere.

 

As i said before, free, and all costs on me.

 

You are being very generous but please keep in mind that 'costs' are not just money involved (which may be much higher than you imagine for just a few seeds) but also time.

For starters, read through this document before even beginning to try and figure out exactly how to navigate the applicable regulations and then fulfil them.

Sad to say, it's cheaper, quicker and easier to pop down to the local garden centre and simply buy an Acer griseum grown locally.

 

As of today my 3-year old seedling, planted in the ground earlier this year, has lost almost all of its leaves. I thought it would do well in that spot because several palmatums are having a great time in the same location. I was wrong (first two pictures).
The 3 second year seedlings I have in a pot in our screened porch seem to be doing much better. In heavy clay soil from the yard… go figure. I am very curious to see how the hybrid one will do next year (last picture).
See post #187 for pictures from this spring of the potted ones.

Welcome back to my thread. Let me get this straight, your feelings were hurt because people haven't taken you up on your offer so you decide a proper response would be to tell them to stick it?
Sooo...trying to see the balance here, not taking someone up on an offer compared to.... being rude...I think you lose this 'battle' Sir.

 

im a bit late but how are the griseums now?

 

I'm not sure if you meant me who started the thread but my seeds are in the ground after a couple of seasons of stratification. This Spring is when I will find out if any of them are viable...and if they are, if the deer will eat them.

 

If you do see some try scoring some with a knife and cracking them open to extract the embryo, It will help them along.

 

Still going strong…

 

Amazing success @Whachamacollit

 

So, this thread is a bit of a gem. I have been looking for details on the challenges of propagating Acer griseum, and all the roots of my research are in this thread. In response to this comment, I would say that Acer saccharum is not a suitable rootstock for Acer griseum, but instead, Acer pseudoplatanus. My source for this is a report fromt he Acer griseum preservation project, where they tested both of these species as understock and didn't get a single success wth A. saccharum, but had 71.4% success with A. pseudoplatanus. Here is a link to the paper. https://ipps.org/uploads/docs/5bER Bachtell 2019.pdf

 

Hello Tim, are you still out there in this forum? I live in the UK, and have been trying to germinate Acer griseum seeds for one season. I believe that I have one seedling out of about 150 seeds, that have been planted in general purpose compost and cold stratified by leaving them outside over the winter. My seeds are from a mixture of trees from public gardens in the South East of the UK. For the next season, I would be very interested to follow your method. For my first attempt, I think I've probably done okay, considering the challenges everyone here has been having with these seeds, but, it would be nice to make an improvment next year, and I want to get ready for seed collecting season. You offered to provide seeds, but, I think it's very impractical to import seeds from mainland Europe into the UK, but, I would be very grateful for some guidance and encouragement.

 

Hey Ian,
I’m sorry but after some not so very nice responses on this forum i didn’t come back to it and lost my interest in propagating Acer Griseums.
I still have 125 or so left and some in my garden are about 1,5 meters tall. The ones on the photo are a bit smaller and are in a sheltered place for one more year.

 

Hello Tim! I'm so glad that you are there. I am very excited about your experience with these seeds, as well as the photo story that you have shared regarding their growth! I have 43 Acer griseum seeds that I wasn't planning to plant. I picked them two weeks ago from the branches of a tree that was not yet in leaf, and they have been in the pocket of my coat hanging over a radiator. But since your advice is that stratification is not necessary, then I will plant them. I have ordered my 90% GA3, and it will come in 3 days approx. I will add one gram of that to 1 litre of bottled mineral water and let it dissolve over a day, shaking every now and then. I will extract the embryos from the samaras, and submerge them in this solution in a tray, covered by cling flim (so the liquid doesn't evaporate), in a warm place in my house for 24 hours. I will then dry the seeds, and plant in a very well drained seed compost and again, keep somewhere warm, ideally in a propagator, until they germinate. Does this sound good to you? I also have about 30 Acer palmatum 'Osakasuki' seeds that I picked on the same day. I have had a bad germination rate from these, so I am gonig to follow the process with these too. I'm not sure I will be able to extract the seeds from the samaras, as they are very small, but I will follow the rest of the steps. My only concern is the quality of my GA3. I have ordered it from ebay, and so, it is possible that I have bought some talcum powder ;) I will post my results here, as I think this post is an extremely interesting discussion on the challenges of growing A. griseum from seed.
