She gave a sharp slap to a spiky, dark red plant as she spoke, making it draw in the long feelers that had been inching sneakily over her shoulder.

Does draw here mean 'to pull or drag (something such as a vehicle) so as to make it follow behind'? So it means the plant pulled out its feelers?
Then what's the role of 'in' here? feel like it's not necessary here.. Or does this phrase have completely different meaning?
