If you are talking about a seedling that after a while can grow independently without caring too much for it because it is not so frail any more, what would you say? Is it autonomous/self-sufficient (though I think these two are not really applicable to this case) or simply established (which is the term usually linked to plants and their development)?

    Self-sufficient implies that something has everything it needs for itself, it does not need any help or resource from outside, which wouldn't be the case with a plant.

    Autonomous as in this dictionary definition (3A) does not I think quite mean that something is no longer frail and can grow by itself.

    Established looks best.
