but he isnt on the ground

Answer 1

It uses its leaves for the job.

>Bellossom does not possess feet; in the anime, its center-most leaves bent as it was getting ready to spring, suggesting that it uses its leaves as substitutes for feet or legs. However, the Pokédex does classify it as a biped.

Answer 2

Maybe this was just an animation error that slipped by the animators. Or maybe it balanced on its dress? But I think the first choice is more believable.
