ELI5: Do plants have unique DNA like humans? For example, if there were two gardenia bushes and a flower fell to the ground, could it be determined which one it came from like genetic testing etc on humans?

Sort of?

Plants reproduce sexually like humans and animals, that is what seeds and pollen and stuff do and when they do that they they have different DNA.  


plants also have a thing that animals don't, where you can slice a part off a plant and if you plant it carefully it will keep living and growing into a new plant pretty easy. People that make fruit and flowers and stuff love this, you can get a nice plant growing then slice parts off it forever and ever to make exact identical copies. So a lot of stuff like flowers and fruit are just 'cuttings' of other identical plants. Like we don't ever plant banana seeds, there is just one banana plant that everyone has copied over and over for decades.   


So some sorts of flowers, yeah, you could find the bush, but some are grafts or cuttings and are basically endless natural clones.
