Christmas cactus

Christmas Cactus- Prized for their blooms, which come in shades of red, pink, and purple, they get their name from the time of year they bloom. To insure the best blooms, don’t move them once they are brought home. Like the ficus, they hate being moved and will complain by shedding their buds and flowers. From spring to fall, keep moist, but in winter, allow the soil to dry out between waterings.
