Dear Friends, This is an impossible question. 1. Each day my "favorite" can change because it comes into bloom, emerges from dormancy or makes a statement. 2. Even a group of plants - Begonias, or Iris or Cactus can change from season to season. 3. Also important is that the web introduces us to new, never before seen and MUST HAVE plants we can't possibly obtain or grow, but love at first sight. (PBS is guilty here) 4. Finally , every plant breeder or seed grower is always hoping that the next seedling, the next generation, will be a combination of all the new characters they are hoping for. The 'plant of the future' will be a new favorite. Favorite plant? Impossible. Any and all are candidates. Best Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
