Amaryllis (genus Hippeastrum) are popular bulb plants known for their large, trumpet-shaped flowers that bloom in winter, offering vibrant colors like red, pink, white, and orange, lasting several weeks indoors. They are easy to grow, needing bright, indirect light, and are often given as holiday gifts because they are grown from bulbs that contain everything needed for a spectacular show. After blooming, they can be maintained to rebloom annually by providing light, water, and a dormancy period.
