The holiday season just isn't complete without the radiant blooms of Amaryllis. Luckily, these festive flowers are among the easiest to grow and make excellent long-term houseplants. Grow them indoors during the winter for stunning centerpieces and move them outside for a refreshing summer vacation. In warmer regions, Amaryllis are content outdoors year-round and offer vibrant displays of color in the spring. Oh, and if you love cut flowers like we do, then you'll be amazed by how long these beauties last in vases!
