My princess plant is not blooming. I live in the SF Bay Area; it is facing west so gets the afternoon sun. It has been in this same location for a number of years and up until a year ago, it bloomed continuously from spring to winter, and then sometimes during the winter. My neighbor to the east has a huge plant, with the same exposure, and it's a riot of color. What should I be doing to get mine to bloom, if anything? Thanks. Lois
