Congrats Coolslaw, those are peonies. 👏🏻 Is there anyway you could leave them there and wait until Fall? Hopefully they will bloom this year, and you can see what color they are in order to place them in the best spot for future Spring blooms .
If you have some nice compost, put some in a ring around the plant but do not let it touch the stems. That will help it grow this Spring since they've probably been neglected by your fiancée.
Good luck.
