His hand doesn't pick it up so much as swing at it, and there's a sort of crunching feeling coming from the place where the flower is. It then disappears from his sight, and a smaller version of the flower lands on the ground, before zooming towards him and appearing in his hand.
He can now feel some sort of... area in his mind? A new sense of sorts? He can clearly see - though not with his eyes - a sort of array of square slots in his mind, with a larger grid above it, and then a small 2x2 grid above that. The flower in his hand occupies the first slot in the first array of slots, which feels closer to him somehow than the rest of the grid.
