Overwintering agapanthus in house

I am in Zone 5 in British Columbia. I have two container grown agapanthus plants to overwinter.
I have them at the moment in nothern aspect about 60F in back porch, temp. 65F day and 60F night, and am keeping watered.

Would I be better off in a cool room in the basement with much less light.

Also, should I keep them watered, since they are evergreen?
Thank you. Jennifer

 

Yes, they will need light and moisture all winter. Locate where they will not freeze. Not a house plant, you will have to continue providing intermediate conditions.

 

Thank you for your help with my agapanthus. Jenny
