I believe navel oranges are also reproduced asexually; I'm not sure if it's via grafting, or something more like true cloning.

Also, aren't some varieties of lawn grass (zoysia, St. Augustine) propagated via cuttings instead of seeding?

Some animal research is done using genetically very homogenous lineages; for example, there are varieties of lab mice that have been inbred for many generations to the point where pretty nearly all visible genetic variation has been eliminated. Not quite clones, but pretty close.

I suspect the result is going to be "we planted genetically identical trees in different places; they grew differently".
