Acer palmatum cultivars that are grafted often grow very slowly if on their own roots.  Grafting a cultivated variety scion onto common seedling rootstock make the tree grow faster and survive more harsh conditions.  Once you have the size trunk and structure you want though, air-layers from cultivars can survive and live long lives.

My go-to source for Acer palmatum cultivar information is Masayoshi Yano's Book For Maples.  It's on Amazon from time to time.  I went to Oregon in 2005 for his talk at the Portland Japanese Garden and his thoughts on cultivar names in America and in some cases Europe were that names often change to increase sales.  He discovered a number of cultivars and assisted in naming quite a few (after tracing parentage and all that).  Vertrees and the van Gelderen books on maples are also good to have; especially if you want to see what the trees look like when they are mature.  Dirr's books will give you a no bs assessment of how many popular cultivars do in America.  His cultivar Acer palmatum 'Glowing Embers', does very well in in the Southeast.  Acer palmatum 'Tobiosho' is a great seedling selection from Iseli Nursery that is also quite tough.  I'm also partial to 'Sharp's Pygmy'.  Here's a photo of an air-layered one on a ten year plan of trunk removal and compaction about three years in.  Photos taken last year.

Rare species and cultivars are often rare because they are easy to kill  ;D.
