Ken - Nearly all full-sun foliage plants can be grown indoors if they are kept close to and directly in front of a sunny, unobstructed, uncovered window. Of course, when indoors they don't grow nearly as rapidly or as large. They also require some acclimatization when moved to reduced indoor light. The better nursery growers start to acclimate plants sold for indoor use several months prior to sale.
Years ago, after caring for many Ficus Elastica indoors, I went to Florida and was stunned to see huge 25-foot Elasticas loaded with dense leaves. That was an eye-opener for me in realizing the difference between growing plants indoors vs. outdoors in warm climates.
