You might find your answer on a remarkable evolving Japanese Maples private collectors site at http://mapledia.blogspot.com/ with excellent photos of Olson's Frosted Strawberries and other unusual maples. Barbara claims to have 250 cultivars some like Beni Kosade and Hana Matoi I've only seen in in YANO's Book for Maples. She intends to post her whole collection as it emerges in the spring of 2007.
Galt, thank you for the info, am thinking maybe grafting on to seedling rootstalk from the desired tree's own seedlings may retain the characteristics.
acerave, Thank you for the link. Will keep an eye to emerging spring foliage on the site to possibly being similar to the trees pictured here. Not familiar with "Yano" book. sounds interesting.
