Hi, I am sorry I am late responding but I just saw the post and here I am.
The plant with the green center and the white on the outside is Chlorophytum comosum 'Variegatum'. The other with the white center and the green down the edge is Chlorophytum comosum 'Vittatum'.
Hope this helps. For those of you on facebook, I started a group where all we discuss are spider plants, all the different varieties, etc. we would be happy to have you join if you decide to learn more about spiders. Take a look and jump in.

This page is by no means to take anything away from ATP but there are friends I have on there who do no other gardening but have a single houseplant....not serious gardeners like here. I keep referring people to ATP on all my orders that I send out and telling them to come here if they have serious garden issues or interests.
