These plants, as you can tell by the photo, come in a variety of different types. They all take low light, which is nice because you get a lot of color and texture from a plant that essentially will grow in a dark place.
One thing that I will caution you about: they do want to remain “evenly moist,” which is a lot harder to do than it sounds.
As a general rule, plants are killed by over-watering, so don’t just water every day. Yet you do want the surface of the soil to be moist at all times. What I do is to check the pots a couple of times a week and when they are dry, I water the plants from the bottom. That seems to be working.
Another way to do this–since these are rather small pots and the plants are fairly full in them–is to soak them completely by letting them fill with water several times at a sink until the water drains completely through. That will hold them for quite some time for me (there’s no way for me to tell you how long it will work in your house–my house may be warmer–or cooler–or brighter–or darker than yours. You will get to know after one or two waterings like this).
These plants are readily available online, which is where I got mine. Good garden centers should also have some varieties of at least one or more of these. Even box stores occasionally carry them. I definitely recommend them, provided you observe the careful watering.
