Answer: This family of plants will adapt to growing indoors, but they can be a challenge. They prefer high humidity, which is sometimes difficult to provide indoors. For years, their large leaves, some shaped like elephant's ears, have graced gardens all over the world. They will thrive outside year-round in your zone, but will not tolerate winter temperatures much less than 55 degrees F.
They are from jungles with high overgrowth, therefore filtered light. Shade or protect your plant during the summer, but supply plenty of light in the winter. A spot with morning sun would be ideal.
They need well-drained, fertile soil, so loosen the garden bed and enrich with composted humus or leaves. An inch of mulch around them would help. Mist during the hot times or the leaf edges will crisp. Feed once a month with a general outdoor garden foliage plant food.
I'd wait until the leaf is completely brown and then cut it off the plant, removing just to where the leaf stem meets the main stem of the plant.
Good luck with your anthuriums!
