This is such a popular cultivar of red maple and so adaptable to different climates and planting situations, it should be available at just about any local nursery or garden center that sells trees. Even my local box stores (HD, Lowes) sell them. Have you tried looking locally? I would opt for that over mail order every time - larger trees for a lower price and no shipping charges.

where are you ...

see link .. especially about TIMING ... its getting a bit late.. to be in prime tree planting time...

but that is not to say.. you couldnt buy one.. and hold it until fall planting time ... trees are best planted leafless ... especially if you end up needing to do root surgery for a tree that has been in a pot too long ...

fall is also a great time.. to find one in the color you want .. if you can find a local tree farm ...

where are you ..

Ditto. There is a Garden Watch Dog site does or did list reputable nurseries. I would imagine ordering this fall from whoever on the site that is located in a similar climate to yours would be best. If you are up in the northwest I might say order from Forest Farm in Oregon for example.

The concern with mailorder now is the poor tree with leaves to support is going to cook in a box inside a hot Fed Ex truck all week on the way to you.

If your weather isn't too terrible and you aren't far south where it should be 95 degrees and dry any day now I wouldn't worry much about planting a small locally sourced October Glory and deeply watering it every couple days w/o meaningful rain all summer and fall.

Here is the link to a few vendors on Daves Garden.

The main mail order sites are pretty conservative about shipping periods based on distance and zones, otherwise they would lose their rear ends. So, if they'll ship, you should be OK. If it is container grown, you can pretty much plant any time as long as you are watering as needed.
