SOLVED: Fine leafed maples "Dwarf" ? Need ID Help

Scotia, CA(Zone 9b)

Bob bought these two little darlings at Costco because he knew I was looking for red leaf Japanese maples in a dwarf form to keep in large pots. But they have no name on them and I don't even know if they are small varitety or will become huge trees. Can anyone Id these for me?

Sorry Zany but these could be any one of a number of red, dissect leaved Acer palmatum. You can expect anywhere between a 15ft to 30ft mature height and spread, possibly more. Technically it's not a big tree anyway but if you want it smaller you may have to (cringe) restrict the roots.

Will keeping them in pots restrict the roots or do I need to learn when,where and how to root prune them? I want to keep them about 6-7 ft tall max....if that is possible?

Zany I have one of these. Mine is purple and a dwarf. It is about 6 years old and about 3 1/2 feet high.

Threadleaf Japanese Maple. I've also seen them in Red and Green.

It could be the same cultivar but there are a number that are similar.


Even the dwarf cultivars need some sort of root pruning if they're to be containerised. On the upside they are slow growing but even so, it's a laborious job! I've not root pruned anything before, I was hoping someone who knows would pop by and chime in.

Sue, that looks the same as mine except maybe a bit darker leaves. I sure hope mine are dwarfs and stay small So I don,t end up having to chop them down in a couple years! Yours sure has a nice full shape! I just hope they can be kept in the pots without any special (hard) work.

I hope so too Baa cause I'd hate to kill them by botching the job.
