Apparently,
People have been making synthetic seeds for plants that don't set good seeds very often.
It involved a sort of micro propagation technique,
Where they take a good part of the plant, like an auxiliary bud for example,
Or use a plant 'embryo'
Then put in a medium that it will live and root in,
Then encase the whole thing in a gel coat type covering....
I guess it sprouts and grows eventually.......
