People collect seeds because they like to grow things from seed or they have gardening friends who do.

Each "new" Japanese maple cultivars began as a seed! (Unless it was a mutation or reversion of an existing plant).

It's a grafted plant, you can't grow it from a seed. There are many other grafted Japanese Maples listed that way here. Why would anyone want to collect their seeds also?

A great tree to use in a place you want to use its 'winter red bark' color (like you would use a Coral Bark) and it's beautiful fall YELLOW up against a contrasting grouping with a red like Moonfire, Fireglow or any number of others. Try to always remember the eventual and natural 'shape' of your japanese maple before placement. Too many photos in books show leaf up close but not a full-grown tree. So do your homework. Is it vase-shaped upright, dome-shaped, round and globe-like, or apple-tree like or it is more like a bush? Know its natural shape before you decide where it goes.

Great looking tree, but watch out for late frost

Great colors and excellent hardiness for a japanese maple. It is a fairly slow grower - my tree (from a cutting) is about 4 ft tall with 3/4 inch trunk after 5 years.

The brilliant red winter bark, as bright as Sango kaku, but a little less orange. Small leaves are bright green and turn to a golden-yellow. Great for bonsai. Height in a natural setting would reach a height of 12 - 15'.
