Technically every Japanese maple in existence was from seed at some point.

JMs from seed are highly genetically variable and are not exact clones from the parent plants. Imagine this: 2 JMs are growing in a field. One has green leaves and one has red leaves. They pollinate one another. Each produce 100 seeds each, 200 seedlings grow. Some will be green, some will be red, some will have big leaves, some bigger leaves. Some have frilly leaves, some more regular palmate leaves. Some are slow growing and compact, some grow tall. 3 of them are weeping. 1 of them has yellow fall colour, one has purple, 17 of them are fire engine red, 25 of them are pinky red.

The genetic variance is incredibly high and none of them have the exact genetic make up of the 2 original parent plants.

Because of this variance, specific individual cultivars have been discovered through the years. These cultivars were identified from the millions of seedlings through the ages because of their interesting traits. In order to reproduce more trees of these cultivars they have to be produced through asexual cloning; cuttings, layers, grafting. They can’t be reproduced from seed because the seedlings wouldn’t be exact copies of the parent plant.
