Find Your Ask The Expert: We had a jade plant (Crassula Argentea) – really a bush- that produced large white flowers. It has not since flowered (probably because of trauma). It’s cuttings are just as big as the mother plant but produces no flowers. What has happened? How can I get the mother and it’s cuttings to flower? The cutting is over 3 feet tall and over 3 feet wide. It’s trunk and limbs are thick, thick, thick and the leaves are shiny, oval and dark green. Whenever I take a cutting or remove a leaf, a new branch appears. The mother plant continually flowered clusters of little white petals, each flower being as big as the size of my fist. It flowered for a good ten years then – nothing. Dubious if this will help. -Lynn
Flower Shop Network Plant Expert Reply: Lynn, blooming in these types of plants is caused by shortening the day length. You will need to create an artificial short-day length by limiting the light the plant receives. You can follow the same instructions for re-blooming Poinsettias.

From http://www.easybloom.com/plantlibrary/plant/jade-plant :
Blooms star-shaped, white to pale pink flowers in spring. Encourage bloom by withholding water when the days get short. Expose Jade plants to several weeks of cool nights without water, and then continue watering regularly. You will get blossoms around the shortest day of the year. Warm nights and regular water will keep the plant healthy, but bloomless.
