Do be very careful when you divide your other one to be sure and gently tease the roots apart.
As for id, this site should be helpful.* Fill in what you know about the plant.

Btw, I have no clue where MPLS is.* You might consider adding your state and hardiness zone to your location in your profile.* It will show as mine does.
