I am in central Florida. I have wintered over (with a frost cloth) 3 Pulmerias. The oldest 5 feet tall, bloomed this summer . Blooms last up to 3 months. They are in small (10"/12") pots. They like to be pot bound with a lot of moisture and excellent drainage. Use ONLY a low nitrogen - high phosphorus fertilizer. (10/50/10) in frequent but diluted doses from the first sign of leaf break in the spring. Continue all summer long. Good luck. Dan
