These plants have green leaves with red or white edges and grow slowly.

Most, not all dracaenas prefer lots of sun. Some of these are in a north-east facing room that has a covered porch around all its windows. If you can read a newspaper in the room using only sunlight, it is probably bright enough for these plants. Too much light will bleach out their leaves. Move them to a less sunny location if this happens.

They like soil that is moist, so water when the top inch of soil is dry, letting water run out through the bottom of the pot. Do not let them dry out.  But do water a little less in the winter to prevent rot from setting in from a lack of sunlight.

The white edged dracaena shown here seems to need more humidity than the red edged ones.
