Shower hostess gifts -when to give them?

one.sweet.world

So, I have my shower on Sunday. My mom and sister are hosting it. I bougth my sister an orchid and my mom another plant/flower. It will be obvious when I walk in with them to my sister's house since I can't leave such delicate plants in the car when it is cold. Should I arrive a bit early and give the gifts to them?? 

As I am writing this I realize I have answered my own question! Duh.

I would arrive early I wish I had done it this way but instead I took both my sisters and my mom out to eat a week or so afetr my shower for dinner and gave everyone thier gift then.
