In colder climates mulching or lifting and overwintering is required. The bulbs may be propagated from offsets. Amaryllis bulbs require little watering and are drought tolerant.

Ornamental bulbous plant are home to bulbous plants such as arisaemas and the giant cardiocrinums. Some bulbous plants grow in communities that are adapted to recurrent fires during the dry season (for example, many Iridaceae species). During these periods the plants are dormant and in this way can survive the heat of the fire. The fires clean the surface vegetation, eliminating competition and also supplying nutrients to the ground from the ashes of the burnt plants. When the first rains fall, the bulbs, corms and rhizomes rapidly start to shoot, starting a new period of growth and development sustained by the reserves accumulated
