Perfect care for a pickle plant may well result in flowers. They bloom in the spring or summer, producing a cluster of bright orange flowers.  Increase the amount of direct sun to get those blooms coming. Three to six hours a day is the lower threshold of light levels. For flowers you want much more. Indoor pickles may need a grow light to supplement natural sunbeams. Indoor plants are always more sensitive to ultraviolet light than their outdoor counterparts, so while it's tempting to pop them in full sun all day you may cook the poor thing.  Water when the soil feels completely dry. When you do water flood the plant and allow to drain. This mimics the desert rainstorms the plant evolved to exploit.  Finally be sure to fertilize it gently with a good organic liquid fertilizer. A specialist cactus and succulent fertilizer is ideal, but a half or even quarter strength general purpose liquid plant food is fine. Try not to overdo the nitrogen, however, as that will prompt the plant to grow more leaves, instead of flowers. A low nitrogen option is better.
