Identification: Can you help identify these please

These are all garden centre rescues at various times that didn’t have labels...Any thoughts on their cultivar would be much appreciated. Sorry for the bulk of them..

 

With hundreds of kinds being grown it's going to be pretty tough to come up with reliable identifications using only these small portraits. And several of them of course could be the typical species rather than named forms.

 

Totally agree with Ron, possibly the J D Vertree's book on Japanes maples might help. Another thought, If you purchased a few from one nursery they may have a list of names of their old stock, this could point you in the right direction. At the end of the day even if you dont find the names, you do have eight lovely looking specimens to enjoy.

 

7. looks like Japanese maple / Acer palmatum "Dissectum Nigrum"

 

#1 looks like Acer palmatum 'Suminagashi'.

 

Understood, ill pick up a copy of the reference book you mention,thanks. The first pic is a tree I picked up only a couple of months ago, with quite bad leaf damage as you can see in the background but im pleased with the new growth that has emerged..

 

I thought it might be inaba shidare but you may be correct

 

Yes looks very much like it, thank you

 

There may be many Dissectum named species. To distinguish between those, you should follow several characteristics, like autumn coloration, depth of the lobes etc.

 

Hi, no1 is definitely not Nigrum. Nigrum does not have dissected lobes. I think SLR2009 is right and it is possibly Suminagashi.

 

I was talking about Dissectum Nigrum regarding no7 (seven). Are you sure, that A. palmatum Dissectum Nigrum has no dissected lobes?

I was looking at no 1 (not no 7 disectum) and think it is Suminagashi. Acer palmatum Nigrum does not have dissected lobes. But Acer dissectum Nigrum does.
