Looks to me like an oak Quercus seedling, probably one of the red oak group (Red Oak, Black Oak, Pin Oak, Scarlet Oak, etc.).
I had a lot of fertile seed last year, none of which of course sprouted. So I performed the Caesarian section technique on about 10 clearly viable nutlets. (proving the quality of the seed, there were only a few empty ones). About half of these started to grow, but they all damped off and that was the end of it. Speaking to another friend about the technique, he has the same result. So, we'll see if I get any next or the following year. Good luck with yours. I feel like scarification couldn't hurt, having struggled to get the embryos our.
I ended up with the same result last year. I made a caesarian-section too. None of them sprouted. It doesn't matter with or without Gibberellin acid treatment... (oh, I see you have a podcast with the MrMaple's guys, congrats!)
Hello Acer griseum fans. I was doing a seedling check this morning of all my outdoor seeds, no progress as of yet with this year's Acer griseum, but I do have some Acer palmatum 'Osakazuki' (obvs now only Acer palmatum), Aesculus x negundo and Cornus kousa cotyledons popping up, so it's a great time to see some fruits of ones labour. My one Acer griseum seed that germinated last year survived the winter in my little plastic greenhouse, and has leafed out. I have a picture here. So proud of this brave little seedling! Hello also @emery! I had no idea that when I met you at Westonbirt, you were someone that I had chatted with in this forum!
Hi Ian, hope your doing well, indeed I never put that together either! Still too early here for griseum, even inside. The triflorums are almost into flower, they're always first. @Whachamacollit , I'm not saying you're wrong, but it's awfully hard to say for certain from juvenile leaves. They can be less dissected for very young giseum. Ian, if you have a picture of the buds, or buds swollen before leafing out, that would clear it up. Cheers, -E
Hey, well i grew hundreds of acer griseums from seeds off different trees (see pic) and all off them had dissected leaves from the start, but nature can surprise us time after time.
