Also, the mere injecting of Flowey's flower with Determination didn't animate him.

None of the other flowers Alphy injected became sentient. Although the Determination did effect them a little, because Alphys recorded that their seeds became more determined to stick to things.

And while some of them growing in places where they somehow knew that Frisk would fall is very creepy, and certainly not random.. it might be because a small amount of Asriel/Chara's essense is in them, while the lion's share remained in Flowey.

It took a very specific moment in time for Flowey to animate. And it paralelled the exact time Alpha Gaster attempted his Darkest Experiment. Flowey, like the other flowers, and everything else in Alphy's lab, had already been injected with Determination many times.

It's like Flowey was a puppet, waiting for a puppetmaster.
