Erm, wow, you are really compounding your complete and total lack of study in scientific subjects. That's not "creation," that's actually called engineering. The same way we engineered cattle, corns, bananas, and many others. You need to learn what the word create means.I used to work at a plant nursery. Every year there some "special" new plants that we would order. It's was either a new flower or foliage color, certain type of disease resistance, different shape, different amount of petals etc. these variations didn't come about on there own. There was a human being responsible for their creation.
Also, there is a larger variety of natural flora than we have ever even managed to engineer, it's more possible that a lot of the ones you got that were "special" were even just ones recently added to the collection.
