Native to the coastal mountains of south-eastern Brazil, sclumbergera bridgesii is a popular unusual cactus with dark-green flattened stems divided into leaf-like segments. Fuchsia-like flowers appear in winter from the notches in stems or the tips and last a long time. They are perfectly symmetrical, carmine red, and a shade of pink-purple in the center. This holiday cactus will drop its flower buds when it's stressed from dry soil, low light, blasts of cold air from doorways or repotting while it's in bloom. Once buds set, don't move your plant around. Changes in light and temperature (besides nightly fluctuations) may cause blooms to fall off. 

Repotting Christmas cactus is usually only necessary every 2 to 3 years. Christmas cactus prefers to be slightly pot-bound and blooms best this way. Wait till spring or early summer to repot -- never while it's budding and blooming, which can cause them to drop.

Hardiness Zones: 9a to 11b (20-50 degrees F)
