Answer: If you have a deciduous agapanthus, the foliage will die down in the fall so it won't make a very pretty houseplant, but it will need to go into a protected place to survive over the winter months. If it's an evergreen, it will look nice but will still need a rest and rather cool temperatures during the winter time. Whichever you have, put the plants in a bright, very cool place at 46 degrees. The plants set the flowers in the winter months and need a resting time. Water very little but do not let the foliage dry out. Repot in early spring when you move the plants back outdoors.
