The calla lily carries sleek, trumpet-shaped blooms above smooth, arrow-shaped leaves, a sculptural look that works as well in a bright room as it does in a cut arrangement. Despite the name it is not a true lily; it comes from southern Africa and blooms in a range of colors.

Indoors, give it bright, indirect light with a little gentle morning sun. Keep the soil evenly moist while it is actively growing in spring and summer, then back off the water as it rests in fall and winter before starting the cycle again.
