    We bought 2 Hong Kong orchids two and a half years ago. The first season, some growth and problems with insects but a few flowers. They are now(after three trim backs) full and close to 12 feet tall. We live in Tampa Bay. Just amazed at how fast these grew( we moved from Upstate NY). Any other growing info appreciated!
