  14. What can we do? Evaluate “new” cultivars for consistency of flowering and maintaining a “dwarf” canopy architecture under Hawaii growing conditions. Evaluate pruning strategies on current and “new” cultivars in Hawaii for return bloom and canopy management. Identify cultivars that are capable of off-season flowering. Identify cultivars with resistance to diseases such as powdery mildew and anthracnose. End
